  • Dot Net Code Coverage Test Tools - there is now a choice

    - by TATWORTH
    I have been pleasantly surprised this week to discover that there is a choice of tools for measuring Code Coverage. If you have Visual Studio Team edition, then if you are using MSTEST, then you have built-in code coverage, however even then you may need a standalone tool. The tools I have found are (costs are per seat): 1) NCover  http://www.ncover.com/ (from $199 to $658 per seat) I have used it but it is very expensive. 2) PartCover http://sourceforge.net/projects/partcover/ - Free!  Steep initial learning curve to get it to work. 3) Dot Cover from http://www.jetbrains.com/dotcover/ - Personal licence - normally $99 but at a introductory price of $75 and free for OpenSource Developers (details at http://www.jetbrains.com/dotcover/buy/buy.jsp#opensource_) 4) Test Matrix from http://submain.com/products/testmatrix.aspx - $149 for a licence

  • How to Implement Single Sign-On between Websites

    - by hmloo
    Introduction Single sign-on (SSO) is a way to control access to multiple related but independent systems, a user only needs to log in once and gains access to all other systems. a lot of commercial systems that provide Single sign-on solution and you can also choose some open source solutions like Opensso, CAS etc. both of them use centralized authentication and provide more robust authentication mechanism, but if each system has its own authentication mechanism, how do we provide a seamless transition between them. Here I will show you the case. How it Works The method we’ll use is based on a secret key shared between the sites. Origin site has a method to build up a hashed authentication token with some other parameters and redirect the user to the target site. variables Status Description ssoEncode required hash(ssoSharedSecret + , + ssoTime + , + ssoUserName) ssoTime required timestamp with format YYYYMMDDHHMMSS used to prevent playback attacks ssoUserName required unique username; required when a user is logged in Note : The variables will be sent via POST for security reasons Building a Single Sign-On Solution Origin Site has function to 1. Create the URL for your Request. 2. Generate required authentication parameters 3. Redirect to target site. using System; using System.Web.Security; using System.Text; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string postbackUrl = "http://www.targetsite.com/sso.aspx"; string ssoTime = DateTime.Now.ToString("yyyyMMddHHmmss"); string ssoUserName = User.Identity.Name; string ssoSharedSecret = "58ag;ai76"; // get this from config or similar string ssoHash = FormsAuthentication.HashPasswordForStoringInConfigFile(string.Format("{0},{1},{2}", ssoSharedSecret, ssoTime, ssoUserName), "md5"); string value = string.Format("{0}:{1},{2}", ssoHash,ssoTime, ssoUserName); Response.Clear(); StringBuilder sb = new StringBuilder(); sb.Append("<html>"); sb.AppendFormat(@"<body onload='document.forms[""form""].submit()'>"); sb.AppendFormat("<form name='form' action='{0}' method='post'>", postbackUrl); sb.AppendFormat("<input type='hidden' name='t' value='{0}'>", value); sb.Append("</form>"); sb.Append("</body>"); sb.Append("</html>"); Response.Write(sb.ToString()); Response.End(); } } Target Site has function to 1. Get authentication parameters. 2. Validate the parameters with shared secret. 3. If the user is valid, then do authenticate and redirect to target page. 4. If the user is invalid, then show errors and return. using System; using System.Web.Security; using System.Text; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { if (User.Identity.IsAuthenticated) { Response.Redirect("~/Default.aspx"); } } if (Request.Params.Get("t") != null) { string ticket = Request.Params.Get("t"); char[] delimiters = new char[] { ':', ',' }; string[] ssoVariable = ticket.Split(delimiters, StringSplitOptions.None); string ssoHash = ssoVariable[0]; string ssoTime = ssoVariable[1]; string ssoUserName = ssoVariable[2]; DateTime appTime = DateTime.MinValue; int offsetTime = 60; // get this from config or similar try { appTime = DateTime.ParseExact(ssoTime, "yyyyMMddHHmmss", null); } catch { //show error return; } if (Math.Abs(appTime.Subtract(DateTime.Now).TotalSeconds) > offsetTime) { //show error return; } bool isValid = false; string ssoSharedSecret = "58ag;ai76"; // get this from config or similar string hash = FormsAuthentication.HashPasswordForStoringInConfigFile(string.Format("{0},{1},{2}", ssoSharedSecret, ssoTime, ssoUserName), "md5"); if (string.Compare(ssoHash, hash, true) == 0) { if (Math.Abs(appTime.Subtract(DateTime.Now).TotalSeconds) > offsetTime) { //show error return; } else { isValid = true; } } if (isValid) { //Do authenticate; } else { //show error return; } } else { //show error } } } Summary This is a very simple and basic SSO solution, and its main advantage is its simplicity, only needs to add a single page to do SSO authentication, do not need to modify the existing system infrastructure.

  • My Feelings About Microsoft Surface

    - by Valter Minute
    Advice: read the title carefully, I’m talking about “feelings” and not about advanced technical points proved in a scientific and objective way I still haven’t had a chance to play with a MS Surface tablet (I would love to, of course) and so my ideas just came from reading different articles on the net and MS official statements. Remember also that the MVP motto begins with “Independent” (“Independent Experts. Real World Answers.”) and this is just my humble opinion about a product and a technology. I know that, being an MS MVP you can be called an “MS-fanboy”, I don’t care, I hope that people can appreciate my opinion, even if it doesn’t match theirs. The “Surface” brand can be confusing for techies that knew the “original” surface concept but I think that will be a fresh new brand name for most of the people out there. But marketing department are here to confuse people… so I can understand this “recycle” of an existing name. So Microsoft is entering the hardware arena… for me this is good news. Microsoft developed some nice hardware in the past: the xbox, zune (even if the commercial success was quite limited) and, last but not least, the two arc mices (old and new model) that I use and appreciate. In the past Microsoft worked with OEMs and that model lead to good and bad things. Good thing (for microsoft, at least) is market domination by windows-based PCs that only in the last years has been reduced by the return of the Mac and tablets. Google is also moving in the hardware business with its acquisition of Motorola, and Apple leveraged his control of both the hardware and software sides to develop innovative products. Microsoft can scare OEMs and make them fly away from windows (but where?) or just lead the pack, showing how devices should be designed to compete in the market and bring back some of the innovation that disappeared from recent PC products (look at the shelves of your favorite electronics store and try to distinguish a laptop between the huge mass of anonymous PCs on displays… only Macs shine out there…). Having to compete with MS “official” hardware will force OEMs to develop better product and bring back some real competition in a market that was ruled only by prices (the lower the better even when that means low quality) and no innovative features at all (when it was the last time that a new PC surprised you?). Moving into a new market is a big and risky move, but with Windows 8 Microsoft is playing a crucial move for its future, trying to be back in the innovation run against apple and google. MS can’t afford to fail this time. I saw the new devices (the WinRT and Pro) and the specifications are scarce, misleading and confusing. The first impression is that the device looks like an iPad with a nice keyboard cover… Using “HD” and “full HD” to define display resolution instead of using the real figures and reviving the “ClearType” brand (now dead on Win8 as reported here and missed by people who hate to read text on displays, like myself) without providing clear figures (couldn’t you count those damned pixels?) seems to imply that MS was caught by surprise by apple recent “retina” displays that brought very high definition screens on tablets.Also there are no specifications about the processors used (even if some sources report NVidia Tegra for the ARM tablet and i5 for the x86 one) and expected battery life (a critical point for tablets and the point that killed Windows7 x86 based tablets). Also nothing about the price, and this will be another critical point because other platform out there already provide lots of applications and have a good user base, if MS want to enter this market tablets pricing must be competitive. There are some expansion ports (SD and USB), so no fixed storage model (even if the specs talks about 32-64GB for RT and 128-256GB for pro). I like this and don’t like the apple model where flash memory (that it’s dirt cheap used in thumdrives or SD cards) is as expensive as gold (or cocaine to have a more accurate per gram measurement) when mounted inside a tablet/phone. For big files you’ll be able to use external media and an SD card could be used to store files that don’t require super-fast SSD-like access times, I hope. To be honest I really don’t like the marketplace model and the limitation of Windows RT APIs (no local database? from a company that based a good share of its success on VB6+Access!) and lack of desktop support on the ARM (even if the support is here and has been used to port office). It’s a step toward the consumer market (where competitors are making big money), but may impact enterprise (and embedded) users that may not appreciate Windows 8 new UI or the limitations of the new app model (if you aren’t connected you are dead ). Not having compatibility with the desktop will require brand new applications and honestly made all the CPU cycles spent to convert .NET IL into real machine code in the past like a huge waste of time… as soon as a new processor architecture is supported by Windows you still have to rewrite part of your application (and MS is pushing HTML5+JS and native code more than .NET in my perception). On the other side I believe that the development experience provided by Visual Studio is still miles (or kilometres) ahead of the competition and even the all-uppercase menu of VS2012 hasn’t changed this situation. The new metro UI got mixed reviews. On my side I should say that is very pleasant to use on a touch screen, I like the minimalist design (even if sometimes is too minimal and hides stuff that, in my opinion, should be visible) but I should also say that using it with mouse and keyboard is like trying to pick your nose with boxing gloves… Metro is also very interesting for embedded devices where touch screen usage is quite common and where having an application taking all the screen is the norm. For devices like kiosks, vending machines etc. this kind of UI can be a great selling point. I don’t need a new tablet (to be honest I’m pretty happy with my wife’s iPad and with my PC), but I may change my opinion after having a chance to play a little bit with those new devices and understand what’s hidden under all this mysterious and generic announcements and specifications!

  • Null Values And The T-SQL IN Operator

    - by Jesse
    I came across some unexpected behavior while troubleshooting a failing test the other day that took me long enough to figure out that I thought it was worth sharing here. I finally traced the failing test back to a SELECT statement in a stored procedure that was using the IN t-sql operator to exclude a certain set of values. Here’s a very simple example table to illustrate the issue: Customers CustomerId INT, NOT NULL, Primary Key CustomerName nvarchar(100) NOT NULL SalesRegionId INT NULL   The ‘SalesRegionId’ column contains a number representing the sales region that the customer belongs to. This column is nullable because new customers get created all the time but assigning them to sales regions is a process that is handled by a regional manager on a periodic basis. For the purposes of this example, the Customers table currently has the following rows: CustomerId CustomerName SalesRegionId 1 Customer A 1 2 Customer B NULL 3 Customer C 4 4 Customer D 2 5 Customer E 3   How could we write a query against this table for all customers that are NOT in sales regions 2 or 4? You might try something like this: 1: SELECT 2: CustomerId, 3: CustomerName, 4: SalesRegionId 5: FROM Customers 6: WHERE SalesRegionId NOT IN (2,4)   Will this work? In short, no; at least not in the way that you might expect. Here’s what this query will return given the example data we’re working with: CustomerId CustomerName SalesRegionId 1 Customer A 1 5 Customer E 5   I was expecting that this query would also return ‘Customer B’, since that customer has a NULL SalesRegionId. In my mind, having a customer with no sales region should be included in a set of customers that are not in sales regions 2 or 4.When I first started troubleshooting my issue I made note of the fact that this query should probably be re-written without the NOT IN clause, but I didn’t suspect that the NOT IN clause was actually the source of the issue. This particular query was only one minor piece in a much larger process that was being exercised via an automated integration test and I simply made a poor assumption that the NOT IN would work the way that I thought it should. So why doesn’t this work the way that I thought it should? From the MSDN documentation on the t-sql IN operator: If the value of test_expression is equal to any value returned by subquery or is equal to any expression from the comma-separated list, the result value is TRUE; otherwise, the result value is FALSE. Using NOT IN negates the subquery value or expression. The key phrase out of that quote is, “… is equal to any expression from the comma-separated list…”. The NULL SalesRegionId isn’t included in the NOT IN because of how NULL values are handled in equality comparisons. From the MSDN documentation on ANSI_NULLS: The SQL-92 standard requires that an equals (=) or not equal to (<>) comparison against a null value evaluates to FALSE. When SET ANSI_NULLS is ON, a SELECT statement using WHERE column_name = NULL returns zero rows even if there are null values in column_name. A SELECT statement using WHERE column_name <> NULL returns zero rows even if there are nonnull values in column_name. In fact, the MSDN documentation on the IN operator includes the following blurb about using NULL values in IN sub-queries or expressions that are used with the IN operator: Any null values returned by subquery or expression that are compared to test_expression using IN or NOT IN return UNKNOWN. Using null values in together with IN or NOT IN can produce unexpected results. If I were to include a ‘SET ANSI_NULLS OFF’ command right above my SELECT statement I would get ‘Customer B’ returned in the results, but that’s definitely not the right way to deal with this. We could re-write the query to explicitly include the NULL value in the WHERE clause: 1: SELECT 2: CustomerId, 3: CustomerName, 4: SalesRegionId 5: FROM Customers 6: WHERE (SalesRegionId NOT IN (2,4) OR SalesRegionId IS NULL)   This query works and properly includes ‘Customer B’ in the results, but I ultimately opted to re-write the query using a LEFT OUTER JOIN against a table variable containing all of the values that I wanted to exclude because, in my case, there could potentially be several hundred values to be excluded. If we were to apply the same refactoring to our simple sales region example we’d end up with: 1: DECLARE @regionsToIgnore TABLE (IgnoredRegionId INT) 2: INSERT @regionsToIgnore values (2),(4) 3:  4: SELECT 5: c.CustomerId, 6: c.CustomerName, 7: c.SalesRegionId 8: FROM Customers c 9: LEFT OUTER JOIN @regionsToIgnore r ON r.IgnoredRegionId = c.SalesRegionId 10: WHERE r.IgnoredRegionId IS NULL By performing a LEFT OUTER JOIN from Customers to the @regionsToIgnore table variable we can simply exclude any rows where the IgnoredRegionId is null, as those represent customers that DO NOT appear in the ignored regions list. This approach will likely perform better if the number of sales regions to ignore gets very large and it also will correctly include any customers that do not yet have a sales region.

  • IncidentsTracker v1.2 Screenshots

    - by samkea
    he IncidentsTracker v1.2 System is a system that was developed to track Incidents happening in any particular country. It is incorporated with a maping component to enable end users search for places where an incident has happened, enter data about it and then produce reports.It's a Winforms software that was developed in a plugin style using C#  with an extensibility pattern/framework. It sits on an SQl Server backend but can also use any other databases prefered. Its Administrator just has to add the path where the database will be and it will autio create the database. This software was orignally developed to help UN Agancies and NGOs in thier work but can also be ustilised by other entities like the police, the human rights organisations, roads authority, etc etc. The development of a newer version(IncidentTracker v2) has been started in silverlight.

  • OData &ndash; The easiest service I can create

    - by Jon Dalberg
    I wanted to create an OData service with the least amount of code so I fired up Visual Studio and got cracking. I decided to serve up a list of naughty words and make them read-only. Create a new web project. I created an empty MVC 2 application but MVC is not required for OData. Add a new WCF Data Service to the project. I named mine NastyWords.svc since I’m serving up a list of nasty words. Add a class to expose via the service: NastyWord 1: [DataServiceKey("Word")] 2: public class NastyWord 3: { 4: public string Word { get; set; } 5: }   I need to be able to uniquely identify instances of NastyWords for the DataService so I used the DataServiceKey attribute with the “Word” property as the key. I could have added an “ID” property which would have uniquely identified them and would then not need the “DataServiceKey” attribute because the DataService would apply some reflection and heuristics to guess at which property would be the unique identifier. However, the words themselves are unique so adding an “ID” property would be redundantly repetitive. Then I created a data source to expose my NastyWord objects to the service. This is just a simple class with IQueryable<T> properties exposing the entities for my service: 1: public class NastyWordsDataSource 2: { 3: private static IList<NastyWord> words = new List<NastyWord> 4: { 5: new NastyWord{ Word="crap"}, 6: new NastyWord{ Word="darn"}, 7: new NastyWord{ Word="hell"}, 8: new NastyWord{ Word="shucks"} 9: }; 10:   11: public NastyWordsDataSource() 12: { 13: NastyWords = words.AsQueryable(); 14: } 15:   16: public IQueryable<NastyWord> NastyWords { get; private set; } 17: }   Now I can go to the NastyWords.svc class and tell it which data source to use and which entities to expose: 1: public class NastyWords : DataService<NastyWordsDataSource> 2: { 3: // This method is called only once to initialize service-wide policies. 4: public static void InitializeService(DataServiceConfiguration config) 5: { 6: config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); 7: config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; 8: } 9: }   Compile and browse to my NastWords.svc and weep with joy Now I can query my service just like any other OData service. Next time, I’ll modify this service to allow updates to sent so I can build up my list of nasty words. Enjoy!

  • Unity works on my PC but not on the Server. What did I miss?

    I have a web service using Microsoft Unity to hook the pieces together.  It all works fine on my PC but when I put it on the web server, I receive this error message: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail]: The value of the property 'type' cannot be parsed. The error is: Method 'GetClaimsForUser' in type 'WebService.Implementation.ClaimsRetriever' from assembly 'WebService.Implementation, Version=1.0.0.0, Culture=neutral, PublicKeyToken=62cac0f1a908971a' does not have an implementation.

  • New Office 2010 theme added for creating current UIs

    - by Webgui
    Visual WebGui offers its developers a set of out-of-the-box themes which they can easily apply to their applications. This allows developers to focus on the development and business logic rather than dealing with UI design missions. However, design tools and customization freedom are available for those who need to customize current themes or create their own custom theme. As part of the constant updates and enhancements to Visual WebGui and its developer CompanionKit a new available theme was added last week. The new theme applies the latest Microsoft UI - Office 2010 to Visual WebGui and allows developers and/or end users (of 6.4.0 and above) to switch their Web applications UI to the successful design of Office 2010. After the latest update the new theme is integrated into the Visual WebGui Developers CompanionKit which now matches Visual WebGui 6.4.0 Release version's infrastructure. The update also includes several enhancements to existing controls and features and the addition of some new ones. Go to the CompanionKit

    Having previously talked about the lack of the traditional HAT in BizTalk 2009, the question then becomes how do you replicate some of the functionality that was previsouly relied on? In BizTalk 2004 we had a query in HAT to return the messages received in the last day.  While not a direct replacement the following query replicates some of the usefullness of this query in a BizTalk 2009 hatless environment. Basically we are creating a query to search for the last one hundred tracked messages that were received by BizTalk: Coming up: Messages - last 100 sent Messages - last 50 suspended Service instances - last 100

  • SharePoint For Newbie Developers: Code Scope

    - by Mark Rackley
    So, I continue to try to come up with diagrams and information to help new SharePoint developers wrap their heads around this SharePoint beast, especially when those newer to development are on my team. To that end, I drew up the below diagram to help some of our junior devs understand where/when code is being executed in SharePoint at a high level. Note that I say “High Level”… This is a simplistic diagram that can get a LOT more complicated if you want to dive in deeper.  For the purposes of my lesson it served its purpose well. So, please no comments from you peanut gallery about information 3 levels down that’s missing unless it adds to the discussion.  Thanks So, the diagram below details where code is executed on a page load and gives the basic flow of the page load. There are actually many more steps, but again, we are staying high level here. I just know someone is still going to say something like “Well.. actually… the dlls are getting executed when…”  Anyway, here’s the diagram with some information I like to point out: Code Scope / Where it is executed So, looking at the diagram we see that dlls and XSL are executed on the server and that JavaScript/jQuery are executed on the client. This is the main thing I like to point out for the following reasons: XSL (for the most part) is faster than JavaScript I actually get this question a lot. Since XSL is executed on the server less data is getting passed over the wire and a beefier machine (hopefully) is doing the processing. The outcome of course is better performance. When You are using jQuery and making Web Service calls you are building XML strings and sending them to the server, then ALL the results come back and the client machine has to parse through the XML and use what it needs and ignore the rest (and there is a lot of garbage that comes back from SharePoint Web Service calls). XSL and JavaScript cannot work together in the same scope Let me clarify. JavaScript can send data back to SharePoint in postbacks that XSL can then use. XSL can output JavaScript and initiate JavaScript variables.  However, XSL cannot call a JavaScript method to get a value and JavaScript cannot directly interact with XSL and call its templates. They are executed in there scope only. No crossing of boundaries here. So, what does this all mean? Well, nothing too deep. This is just some basic fundamental information that all SharePoint devs need to understand. It will help you determine what is the best solution for your specific development situation and it will help the new guys understand why they get an error when trying to call a JavaScript Function from within XSL.  Let me know if you think quick little blogs like this are helpful or just add to the noise. I could probably put together several more that are similar.  As always, thanks for stopping by, hope you learned something new.

  • Visual WebGui launches a new prize-winning challenge for developers

    - by Webgui
    Gizmox is announcing a ListView Challenge where developers can participate by creating and submitting their own implementations of the new extended ListView. "its quite amazing what you can do with it. It opens a lot of new ways to present data in a better and more userfriendly way," says one of the VWG community members who built a three level hierarchal ListView. Watch the hierarchal ListView demo by Visualizer Those ListView implementations will be reviewed and rated and the winner will win a free Professional Studio license $750 worth. The 5 top rated codes will entitle their developers for a cool new T-shirt. The new v6.4 introduces new capabilities with its extended ListView Control. Enter the Challenge The Collapsible Panel enhancement of the ListView Control, along with the Column Type Control, open up the possibilities for potential usage of the ListView control for data display, data entry and as the Collapsible Panel can contain whatever control you like, it can as well contain other ListView controls, thus making it possible to create Hierarchial ListView display of unlimited number of levels. The first enhancement is the introduction of a new column type Control which opens up the possibility for a ListView cell to contain controls like CheckBox, ComboBox, ListBox or even TabControl, Form or another ListView as the contents of that particular cell. This means that the ListView is no longer a display-only control, but has the full potential of being a full blown data entry control as well. The second major enhancement is the introduction of ListViewPanelItem. The ListViewPanelItem behaves exactly the same as it‘s predecessor, the ListViewItem, and in additon it has a Panel Control attached to it, seperate panel for each row in the ListView. This new Panel can be either expanded (visible) or not (hidden) and when expanded, will fill the full width of the ListView, but has adjustable height. Watch a webcast about the extended ListView

    Still have an old AIM email address lying around and would like to forward it to Gmail?  Here's how: 1.  Login to your AIM and click on Settings on the far right 2.  In the left menu click IMAP and POP  3.  This shows you your IMAP and POP setup information for AIM.  We're going to put this into your Gmail account so your Gmail account will check your AIM account and download all AIM emails. 4.  Login to your Gmail, click Settings and click Accounts and Import 5.  Click "Import mail and contacts".  A new window will pop up asking what account you want to import.  Enter your AIM Email Address and click Continue 6.  The next page asks for your password.  Enter your password and click Continue.  Step 2 asks your Import options.  I'd put a checkmark in "Leave a copy of retrieved message on server".  That way all your mail is still stored on AIM if you ever need it. 7.  Click Start import and you're done.  Next screen says it make take several hours up to 2 days before you start seeing imported messages and can check the status at Settings > Accounts and Import

  • Windows Azure Platform eBook Update #2 &ndash; 100 pages of goodness

    - by Eric Nelson
    I previously mentioned I was working on a community authored eBook for the Windows Azure Platform. Well, today I assembled the 20 articles that made it through to the end of the review process into a single eBook – and it looks (and reads) great. Still a lot more to do (and stuff in the way of me doing it) but as a teaser, here is the (very draft) table of contents:

  • Next Post...

    - by James Michael Hare
    The next post on the concurrent collections will be next Monday.  I'm a little behind from my Topeka trip earlier this week, so sorry about the delay! Also, I was thinking about starting a C++ Little Wonders series as well.  Would anyone have an interest in that topic?  I primarily use C# in my development work, but there is still a lot of legacy C++ I work on as well and could share some tips & tricks.

  • PowerShell a constant in a changing world

    - by Rob Addis
    I've been programming for about 20 years now some of my friends have been at it for over 30. I have read many, many manuals and yes it's not my favourite past time. So 10 years ago I made a promise to myself to try and only learn about products which have long life times. I immediately gave up programming GUIs and concentrated on back end development as I decided that these products (Oracle, MQ Series, SQL Server, BizTalk and later WCF, WF) have longer life times and smaller incremental changes than front end products.10 years ago I had no idea how good a decision that would turn out to be. There have been so many different Microsoft products for the front end in that time; multiple versions of Windows Forms, FrontPage, Html, Javascript, ASP.net, Silverlight, SharePoint, WPF and now hopefully a stayer Metro.I remember being at a Microsoft conference in 2006 when Martin Fowler told a crowd of developers (I'm paraphrasing) "If you don't like change then you're in the wrong business!". Well I've been in the business for 20 years and yes I'm a little resistant to change. I like my investment in reading manuals and getting certified to be time well spent!Over the last 2 years I have been writing A LOT of PowerShell script, I think there is a good chance this product will still be around and be used for new development in 10 years, learning it is a good investment.

  • An open plea to Microsoft to fix the serializers in WCF.

    - by Scott Wojan
    I simply DO NOT understand how Microsoft can be this far along with a tool like WCF and it STILL tout it as being an "Enterprise" tool. For example... The following is a simple xsd schema with a VERY simple data contract that any enterprise would expect an "enterprise system" to be able to handle: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="Sample"     targetNamespace="http://tempuri.org/Sample.xsd"     elementFormDefault="qualified"     xmlns="http://tempuri.org/Sample.xsd"     xmlns:mstns="http://tempuri.org/Sample.xsd"     xmlns:xs="http://www.w3.org/2001/XMLSchema">    <xs:element name="SomeDataElement">     <xs:annotation>       <xs:documentation>This documents the data element. This sure would be nice for consumers to see!</xs:documentation>     </xs:annotation>     <xs:complexType>       <xs:all>         <xs:element name="Description" minOccurs="0">           <xs:simpleType>             <xs:restriction base="xs:string">               <xs:minLength value="0"/>               <xs:maxLength value="255"/>             </xs:restriction>           </xs:simpleType>         </xs:element>       </xs:all>       <xs:attribute name="IPAddress" use="required">         <xs:annotation>           <xs:documentation>Another explanation!  WOW!</xs:documentation>         </xs:annotation>         <xs:simpleType>           <xs:restriction base="xs:string">             <xs:pattern value="(([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])\.){3}([1-9]?[0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])"/>           </xs:restriction>         </xs:simpleType>       </xs:attribute>     </xs:complexType>  </xs:element>   </xs:schema>  An minimal example xml document would be: <?xml version="1.0"encoding="utf-8" ?> <SomeDataElementxmlns="http://tempuri.org/Sample.xsd" IPAddress="1.1.168.10"> </SomeDataElement> With the max example being:  <?xml version="1.0"encoding="utf-8" ?> <SomeDataElementxmlns="http://tempuri.org/Sample.xsd" IPAddress="1.1.168.10">  <Description>ddd</Description> </SomeDataElement> This schema simply CANNOT be exposed by WCF.  Let's list why:  svcutil.exe will not generate classes for you because it can't read an xsd with xs:annotation. Even if you remove the documentation, the DataContractSerializer DOES NOT support attributes so IPAddress would become an element this not meeting the contract xsd.exe could generate classes but it is a very legacy tool, generates legacy code, and you still suffer from the following issues: NONE of the serializers support emitting of the xs:annotation documentation.  You'd think a consumer would really like to have as much documentation as possible! NONE of the serializers support the enforcement of xs:restriction so you can forget about the xs:minLength, xs:maxLength, or xs:pattern enforcement. Microsoft... please, please, please, please look at putting the work into your serializers so that they support the very basics of designing enterprise data contracts!!
