  • MySQL Connector/Net 6.5.5 Maintenance Release has been released

    - by fernando
    MySQL Connector/Net 6.5.5, a new maintenance release of our 6.5 series, has been released.  This release is GA quality and is appropriate for use in production environments.  Please note that 6.6 is our latest driver series and is the recommended product for development. It is now available in source and binary form from http://dev.mysql.com/downloads/connector/net/#downloads and mirror sites (note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download site.) The 6.5.5 version of MySQL Connector/Net brings the following fixes: - Fix for ArgumentNull exception when using Take().Count() in a LINQ to Entities query (bug MySql #64749, Oracle bug #13913047). - Fix for type varchar changed to bit when saving in Table Designer (Oracle bug #13916560). - Fix for error when trying to change the name of an Index on the Indexes/Keys editor; along with this fix now users can change the Index type of a new Index which could not be done   in previous versions, and when changing the Index name the change is reflected on the list view at the left side of the Index/Keys editor (Oracle bug #13613801). - Fix for stored procedure call using only its name with EF code first (MySql bug #64999, Oracle bug #14008699). - Fix for List.Contains generates a bunch of ORs instead of more efficient IN clause in   LINQ to Entities (Oracle bug #14016344, MySql bug #64934). - Fix for performance issue in generated EF query: .NET StartsWith/Contains/EndsWith produces MySql's locate instead of Like (MySql bug #64935, Oracle bug #14009363). - Fix for script generated for code first contains wrong alter table and wrong declaration for byte[] (MySql bug #64216, Oracle bug #13900091). - Fix and code contribution for bug Timed out sessions are removed without notification which allow to enable the Expired CallBack when Session Provider times out any session (bug MySql #62266 Oracle bug # 13354935) - Fix for Exception thrown when using cascade delete in an EDM Model-First in Entity Framework (Oracle bug #14008752, MySql bug #64779). - Fix for Session locking issue with MySqlSessionStateStore (MySql bug #63997, Oracble bug #13733054). - Fixed deleting a user profile using Profile provider (MySQL bug #64470, Oracle bug #13790123) - Fix for bug Cannot Create an Entity with a Key of Type String (MySQL bug #65289, Oracle bug #14540202). This fix checks if the type has a FixedLength facet set in order to create a char otherwise should create varchar, mediumtext or longtext types when using a String CLR type in Code First or Model First also tested in Database First. Unit tests added for Code First and ProviderManifest. - Fix for bug "CacheServerProperties can cause 'Packet too large' error". The issue was due to a missing reading of Max_allowed_packet server property when CacheServerProperties is in true, since the value was read only in the first connection but the following pooled connections had a wrong value causing a Packet too large error. Including also a unit test for this scenario. All unit test passed. MySQL Bug #66578 Orabug #14593547. - Fix for handling unnamed parameter in MySQLCommand. This fix allows the mysqlcommand to handle parameters without requiring naming (e.g. INSERT INTO Test (id,name) VALUES (?, ?) ) (MySQL Bug #66060, Oracle bug #14499549). - Fixed inheritance on Entity Framework Code First scenarios. Discriminator column is created using its correct type as varchar(128) (MySql bug #63920 and Oracle bug #13582335). - Fixed "Trying to customize column precision in Code First does not work" (MySql bug #65001, Oracle bug #14469048). - Fixed bug ASP.NET Membership database fails on MySql database UTF32 (MySQL bug #65144, Oracle bug #14495292). - Fix for MySqlCommand.LastInsertedId holding only 32 bit values (MySql bug #65452, Oracle bug #14171960) by changing   several internal declaration of lastinsertid from int to long. - Fixed "Decimal type should have digits at right of decimal point", now default is 2, but user's changes in   EDM designer are recognized (MySql bug #65127, Oracle bug #14474342). - Fix for NullReferenceException when saving an uninitialized row in Entity Framework (MySql bug #66066, Oracle bug #14479715). - Fix for error when calling RoleProvider.RemoveUserFromRole(): causes an exception due to a wrong table being used (MySql bug #65805, Oracle bug #14405338). - Fix for "Memory Leak on MySql.Data.MySqlClient.MySqlCommand", too many MemoryStream's instances created (MySql bug #65696, Oracle bug #14468204). - Added ANTLR attribution notice (Oracle bug #14379162). - Fixed Entity Framework + mysql connector/net in partial trust throws exceptions (MySql bug #65036, Oracle bug #14668820). - Added support in Parser for Datetime and Time types with precision when using Server 5.6 (No bug Number). - Small improvement on MySqlPoolManager CleanIdleConnections for better mysqlpoolmanager idlecleanuptimer at startup (MySql bug #66472 and Oracle bug #14652624). - Fix for bug TIMESTAMP values are mistakenly represented as DateTime with Kind = Local (Mysql bug #66964, Oracle bug #14740705). - Fix for bug Keyword not supported. Parameter name: AttachDbFilename (Mysql bug #66880, Oracle bug #14733472). - Added support to MySql script file to retrieve data when using "SHOW" statements. - Fix for Package Load Failure in Visual Studio 2005 (MySql bug #63073, Oracle bug #13491674). - Fix for bug "Unable to connect using IPv6 connections" (MySQL bug #67253, Oracle bug #14835718). - Added auto-generated values for Guid identity columns (MySql bug #67450, Oracle bug #15834176). - Fix for method FirstOrDefault not supported in some LINQ to Entities queries (MySql bug #67377, Oracle bug #15856964).

  • What build tools do not depend on java (or Ruby)?

    - by Mohamed Meligy
    I'm wondering what generic build tools out there include their binary run-times and do not depend on another environment not shipped with them. For example, ANT requires Java, Rake requires Ruby, etc.. would be great if talking about also target-platform-agnostic tools, where I'd just give whatever command for building, whatever command for testing, etc.. and can then define my artifacts in CI or so. Would see something like that useful for building .NET projects (say, on both Windows .NET and Mono), and Node JS projects especially. I do not want to install Java and / or Ruby if what I want is a .NET build or a Node JS build. This is a bit of general awareness question not an exact problem I'm facing, that's why it's here not on StackOverflow. Update: To explain a bit more, what I'm after is the build script that would run MSBuild for compiling for example ( in .NET, and then maybe several Node/NPM commands in Node, etc..), and then have the rest build/test steps, instead of setting these all in MSBuild (again, in .NET case, also, wondering if there is equivalent story in Node).

  • Learning C# quickly

    - by Niklas H
    I just got a position at a big, well-known C#/.NET company. The thing is that I don't know any C# or .NET at all (they know that) and I want to learn as much as I can before I start, to not waste time (and money). How do I learn C#/.NET quickly and efficiently? Resources? Great tutorials? Videos? EDIT: I forgot to mention that I have a couple of years experience with Java. So I am not new to programming - just new to .NET.

  • Safely deploying changes to production servers

    - by oazabir
    When you deploy incremental changes on a production server, which is running and live all the time, you some times see error messages like “Compiler Error Message: The Type ‘XXX’ exists in both…”. Sometimes you find Application_Start event not firing although you shipped a new class, dll or web.config. Sometimes you find static variables not getting initialized and so on. There are so many weird things happen on webservers when you incrementally deploy changes to the server and the server has been up and running for several weeks. So, I came up with a full proof house keeping steps that we always do whenever we deploy some incremental change to our websites. These steps ensure that the web sites are properly recycled , cached are cleared, all the data stored at Application level is initialized. First of all you should have multiple web servers behind load balancer. This way you can take one server our of the production traffic, do your deployment and house keeping tasks like restarting IIS, and then put it back. Then you can do it for the second server and so on. This ensures there’s no outage for customer. If you can do it reasonable fast, hopefully customers won’t notice discrepancy between the servers some having new code and some having old code. You should only do this when your changes aren’t drastic. For ex, you aren’t delivering a complete revamped UI. In that case, some users hitting server1 with latest UI will suddenly get a completely different experience and then on next page refresh, they might hit server2 with old code and get a totally different experience. This works for incremental non-dramatic changes only.   During deployment you should follow these steps: Take server X out of load balancer so that it does not get any traffic. Stop all windows services on the server. Stop IIS. Delete the Temporary ASP.NET folders of all .NET versions incase you have multiple .NET versions running. You can follow this link. Deploy the changes. Flush any distributed cache you have, for ex, Velocity or Memcached. Start IIS. Start the windows services on the server. Warm up all websites by hitting major URLs on the websites. You should have some automated script to do this. You can use tinyget to hit some major URLs, especially pages that take a lot of time to compile. Read my post on keeping websites warm with zero coding. Put server X back to load balancer so that it starts receiving traffic. That’s it. It should give you a clean deployment and prevent unexpected errors. You should print these steps and hang on the desk of your deployment guys so that they never forget during deployment pressure.

  • Exciting product releases (and one disappointing thing) with Mix10

    - by Jeff
    Sadly, I'm not at Mix this year, for the first time in a few years. It's a little harder to go if you work for Microsoft, oddly enough. And then there's this little guy next to me, who at ten days old really needs his daddy to be around! But oh, the excitement of what Microsoft has in store! It's great to finally see all of these major releases coming together for Microsoft developer products. There is a great deal of excitement among people internally no matter where you work, because there is so much cool stuff in the pipe. In case you live under a rock...Visual Studio 2010 - Great to see all of the positive feedback on the Twitter and what not. I've been using it on one of my home products for awhile, and I really like it. The newer nightly builds of ReSharper also seem to be gaining speed in quality as well. I like the new debugging features, and the text readability is not imagined. Love it.Silverlight 4 - I've been running a couple of minor SL3 apps on my personal sites for awhile now, and I'm thrilled with the platform. With a couple of key concepts down, .NET folk like you and me can do some stellar things with this, and if you're a Mac nerd (like me), it's all kinds of awesome to be able to build stuff for it without the agony of Objective-C and X Code.Windows Phone 7 Series - A few weeks ago you got to see the shiny new UI that went beyond the icon grid, and now you've got the developer story as well. That I can adapt my existing Silverlight apps with minimal effort to work on the phone is pretty powerful. Millions of .NET devs just because phone developers, using the tools they already know. How great is that?ASP.NET MVC2 - The final bits shipped last week, and there was much rejoicing. I love this framework because of the testability and the real ability to get to the true mechanics of HTTP. The other cool thing is the speed at which the framework has evolved. v2 in less than a year is pretty "un-Microsoft" in a lot of eyes.The video of keynotes and sessions is starting to appear on the Mix site, but for reasons I can't understand, they're WMV downloads. For real? Not that helpful for Mac folk. Why wouldn't they be using a Silverlight player?In any case, the thing that continues to motivate me is that getting what you imagine on to the Internet gets easier every year. This is not a new revelation for me. I've only been at Microsoft for four months, but I've felt this way for years. I'm thrilled to be a part of it.

  • Has anyone seen .NET 4 RC MVC2 RTM web apps hogging CPU on Win2008 R2?

    - by kim3er
    We have a number of .NET4 RC ASP.NET MVC2 RTM web applications running on a Windows 2008 R2 server. All behave very well except one that we regularly find running at 99% CPU. It is the most complex of the applications, but is not doing anything extraordinary. It relies on ASP.NET Cache quite heavily, but we have limited the amount of memory it is allowed to use. Does this sound like an issue with the environment? Rich

  • Why was Scala not implemented with C or C++

    - by jpartogi
    Does anybody know why was Scala implemented in Java and .NET instead of C or C++? Most languages are implemented with Cor C++ [i.e Erlang, Python, PHP, Ruby, Perl]. What are the advantages for Scala implemented in Java and .NET other than giving access to Java and .NET libraries? UPDATE Woudln't Scala gain more benefit if it is implemented in C because it can be tuned better rather than relying on JVM?

  • Use-cases for node.js and c#

    - by Chase Florell
    I do quite a bit of ASP.NET work (C#, MVC), but most of it is typical web development. I do Restful architecture using CRUD repositories. Most of my clients don't have a lot of advanced requirements within their applications. I'm now looking at node.js and it's performance implications (I'm addicted to speed), but I haven't delved into it all that much. I'm wondering if node.js can realistically replace my typical web development in C# and ASP.NET MVC (not rewriting existing apps, but when working on new ones) node.js can complement an ASP.NET MVC app by adding some async goodness to the existing architecture. Are there use-cases for/against C# and node.js? Edit I love ASP.NET MVC and am super excited with where it's going. Just trying to see if there are special use cases that would favor node.js

  • Consuming ASMX and WCF Services using jQuery

    - by bipinjoshi
    In the previous part I demonstrated how jQuery animations can add some jazz to your web forms. Now let's see one of the most important feature of jQuery that you will probably use in all data driven websites - accessing server data. In the previous articles you used jQuery methods such as $.get() to make a GET request to the server. More powerful feature, however, is to make AJAX calls to ASP.NET Web Services, Page Methods and WCF services. The $.ajax() method of jQuery allows you to access these services. In fact $.get() method you used earlier internally makes use of $.ajax() method but restricts itself only to GET requests. The $.ajax() method provides more control on how the services are called.http://www.bipinjoshi.net/articles/479571df-7786-4c50-8db6-a798f195471a.aspx

  • it is a good approach to implement dependency injection in a desktop app?

    - by luis_laurent
    Well, the thing is that I am just about to create a Desktop App (with .NET windows forms) And now I just wonder if it would be really a wise choise to use any IoC (StructureMap,Ninject,Spring .Net), I have used them before for Asp.Net web applications but what makes me doubt now is the fact that working with windows forms my business entities will persist when I navigate through tabs and unlike than web forms or mvc apps where it would be necesary to inject my business entity for every new request that is performed, I mean this because of the Asp.Net page life cycle where is performed the initialization and controls instantiation. Maybe I am misunderstanding the point of using an IoC, so please tell me what do you think would be a better choise?

  • Windows Forms Development - Books

    - by Scott
    So I'm reading a book for architecting applications for the enterprise from the Microsoft Press. It's a great book, and I'm learning a lot. However, it's very high level, and can be applied to a lot of different domains (not even just .NET, even though that's how the book is geared). The first project I want to develop after reading the book is a Windows Forms application in .NET 4.0. I want to use a lot of the books concepts to develop the app, but I really want a great Windows Forms dedicated book to read before starting that's really going to tell me all I need to know about developing Windows Forms apps. I found plenty of books for .NET 2.0 and stuff, but nothing for Windows Forms in the new .NET 4.0 Framework. Any suggestions?

  • What server-side language should I learn to be able to start big user-input websites (like twitter, facebook, stackexchange...)?

    - by DarkLightA
    I'm thinking ASP.NET, but I don't really know. Can someone tell me what a good server-side language for the "Zuckerberg-dorm-room-starting-up-a-huge-website" deal? I know the latter used PHP, but as I've understood it that's kind of outdated and C#/ASP.NET is a better way to go about it. Is HTML + CSS + JavaScript + C#/ASP.NET MVC + MySQL a good combination for it? Is MySQL combined in ASP.NET MVC? Also, where's a good tutorial for the server-side language you suggest? As mentioned previously it has to be able to handle massive user-input without much fuss.

  • Relationship between "Task Parallel Library" and "Task-based Asynchronous Pattern"?

    - by Sid
    In the context of C#, .NET 4/4.5 used for an application running on a web-server, what is the relationship between "Task Parallel Library" and "Task-based Asynchronous Pattern"? I understand one is a library and the other is a pattern. But to dig deeper, is it like "The library is used by the pattern to enforce good practices". I'm also not clear if both are supported in .NET 4.0 (with awake and async keywords) Edit: Seems that awake and async are only in .NET 4.5 ...

  • Does Windows 7 have .NET 4 installed by default?

    - by Nasenbaer
    I offered software where .NET 4.0 is needed and promised, that Windows 7 already comes with this framework. If not, the user can use the integrated "Windows Update" function to install the framework. My client said to me there is no Framework on Windows 7 Professional installed already. What are details about the situation of Windows 7 and is there an option to install .NET by using the update function of Windows 7?

  • Making Sense of ASP.NET Paths

    - by Renso
    Making Sense of ASP.NET Paths ASP.Net includes quite a plethora of properties to retrieve path information about the current request, control and application. There's a ton of information available about paths on the Request object, some of it appearing to overlap and some of it buried several levels down, and it can be confusing to find just the right path that you are looking for. To keep things straight I thought it a good idea to summarize the path options along with descriptions and example paths. I wrote a post about this a long time ago in 2004 and I find myself frequently going back to that page to quickly figure out which path I’m looking for in processing the current URL. Apparently a lot of people must be doing the same, because the original post is the second most visited even to this date on this blog to the tune of nearly 500 hits per day. So, I decided to update and expand a bit on the original post with a little more information and clarification based on the original comments. Request Object Paths Available Here's a list of the Path related properties on the Request object (and the Page object). Assume a path like http://www.west-wind.com/webstore/admin/paths.aspx for the paths below where webstore is the name of the virtual. Request Property Description and Value ApplicationPath Returns the web root-relative logical path to the virtual root of this app. /webstore/ PhysicalApplicationPath Returns local file system path of the virtual root for this app. c:\inetpub\wwwroot\webstore PhysicalPath Returns the local file system path to the current script or path. c:\inetpub\wwwroot\webstore\admin\paths.aspx Path FilePath CurrentExecutionFilePath All of these return the full root relative logical path to the script page including path and scriptname. CurrentExcecutionFilePath will return the ‘current’ request path after a Transfer/Execute call while FilePath will always return the original request’s path. /webstore/admin/paths.aspx AppRelativeCurrentExecutionFilePath Returns an ASP.NET root relative virtual path to the script or path for the current request. If in  a Transfer/Execute call the transferred Path is returned. ~/admin/paths.aspx PathInfo Returns any extra path following the script name. If no extra path is provided returns the root-relative path (returns text in red below). string.Empty if no PathInfo is available. /webstore/admin/paths.aspx/ExtraPathInfo RawUrl Returns the full root relative URL including querystring and extra path as a string. /webstore/admin/paths.aspx?sku=wwhelp40 Url Returns a fully qualified URL including querystring and extra path. Note this is a Uri instance rather than string. http://www.west-wind.com/webstore/admin/paths.aspx?sku=wwhelp40 UrlReferrer The fully qualified URL of the page that sent the request. This is also a Uri instance and this value is null if the page was directly accessed by typing into the address bar or using an HttpClient based Referrer client Http header. http://www.west-wind.com/webstore/default.aspx?Info Control.TemplateSourceDirectory Returns the logical path to the folder of the page, master or user control on which it is called. This is useful if you need to know the path only to a Page or control from within the control. For non-file controls this returns the Page path. /webstore/admin/ As you can see there’s a ton of information available there for each of the three common path formats: Physical Path is an OS type path that points to a path or file on disk. Logical Path is a Web path that is relative to the Web server’s root. It includes the virtual plus the application relative path. ~/ (Root-relative) Path is an ASP.NET specific path that includes ~/ to indicate the virtual root Web path. ASP.NET can convert virtual paths into either logical paths using Control.ResolveUrl(), or physical paths using Server.MapPath(). Root relative paths are useful for specifying portable URLs that don’t rely on relative directory structures and very useful from within control or component code. You should be able to get any necessary format from ASP.NET from just about any path or script using these mechanisms. ~/ Root Relative Paths and ResolveUrl() and ResolveClientUrl() ASP.NET supports root-relative virtual path syntax in most of its URL properties in Web Forms. So you can easily specify a root relative path in a control rather than a location relative path: <asp:Image runat="server" ID="imgHelp" ImageUrl="~/images/help.gif" /> ASP.NET internally resolves this URL by using ResolveUrl("~/images/help.gif") to arrive at the root-relative URL of /webstore/images/help.gif which uses the Request.ApplicationPath as the basepath to replace the ~. By convention any custom Web controls also should use ResolveUrl() on URL properties to provide the same functionality. In your own code you can use Page.ResolveUrl() or Control.ResolveUrl() to accomplish the same thing: string imgPath = this.ResolveUrl("~/images/help.gif"); imgHelp.ImageUrl = imgPath; Unfortunately ResolveUrl() is limited to WebForm pages, so if you’re in an HttpHandler or Module it’s not available. ASP.NET Mvc also has it’s own more generic version of ResolveUrl in Url.Decode: <script src="<%= Url.Content("~/scripts/new.js") %>" type="text/javascript"></script> which is part of the UrlHelper class. In ASP.NET MVC the above sort of syntax is actually even more crucial than in WebForms due to the fact that views are not referencing specific pages but rather are often path based which can lead to various variations on how a particular view is referenced. In a Module or Handler code Control.ResolveUrl() unfortunately is not available which in retrospect seems like an odd design choice – URL resolution really should happen on a Request basis not as part of the Page framework. Luckily you can also rely on the static VirtualPathUtility class: string path = VirtualPathUtility.ToAbsolute("~/admin/paths.aspx"); VirtualPathUtility also many other quite useful methods for dealing with paths and converting between the various kinds of paths supported. One thing to watch out for is that ToAbsolute() will throw an exception if a query string is provided and doesn’t work on fully qualified URLs. I wrote about this topic with a custom solution that works fully qualified URLs and query strings here (check comments for some interesting discussions too). Similar to ResolveUrl() is ResolveClientUrl() which creates a fully qualified HTTP path that includes the protocol and domain name. It’s rare that this full resolution is needed but can be useful in some scenarios. Mapping Virtual Paths to Physical Paths with Server.MapPath() If you need to map root relative or current folder relative URLs to physical URLs or you can use HttpContext.Current.Server.MapPath(). Inside of a Page you can do the following: string physicalPath = Server.MapPath("~/scripts/ww.jquery.js")); MapPath is pretty flexible and it understands both ASP.NET style virtual paths as well as plain relative paths, so the following also works. string physicalPath = Server.MapPath("scripts/silverlight.js"); as well as dot relative syntax: string physicalPath = Server.MapPath("../scripts/jquery.js"); Once you have the physical path you can perform standard System.IO Path and File operations on the file. Remember with physical paths and IO or copy operations you need to make sure you have permissions to access files and folders based on the Web server user account that is active (NETWORK SERVICE, ASPNET typically). Note the Server.MapPath will not map up beyond the virtual root of the application for security reasons. Server and Host Information Between these settings you can get all the information you may need to figure out where you are at and to build new Url if necessary. If you need to build a URL completely from scratch you can get access to information about the server you are accessing: Server Variable Function and Example SERVER_NAME The of the domain or IP Address wwww.west-wind.com or 127.0.0.1 SERVER_PORT The port that the request runs under. 80 SERVER_PORT_SECURE Determines whether https: was used. 0 or 1 APPL_MD_PATH ADSI DirectoryServices path to the virtual root directory. Note that LM typically doesn’t work for ADSI access so you should replace that with LOCALHOST or the machine’s NetBios name. /LM/W3SVC/1/ROOT/webstore Request.Url and Uri Parsing If you still need more control over the current request URL or  you need to create new URLs from an existing one, the current Request.Url Uri property offers a lot of control. Using the Uri class and UriBuilder makes it easy to retrieve parts of a URL and create new URLs based on existing URL. The UriBuilder class is the preferred way to create URLs – much preferable over creating URIs via string concatenation. Uri Property Function Scheme The URL scheme or protocol prefix. http or https Port The port if specifically specified. DnsSafeHost The domain name or local host NetBios machine name www.west-wind.com or rasnote LocalPath The full path of the URL including script name and extra PathInfo. /webstore/admin/paths.aspx Query The query string if any ?id=1 The Uri class itself is great for retrieving Uri parts, but most of the properties are read only if you need to modify a URL in order to change it you can use the UriBuilder class to load up an existing URL and modify it to create a new one. Here are a few common operations I’ve needed to do to get specific URLs: Convert the Request URL to an SSL/HTTPS link For example to take the current request URL and converted  it to a secure URL can be done like this: UriBuilder build = new UriBuilder(Request.Url); build.Scheme = "https"; build.Port = -1; // don't inject portUri newUri = build.Uri; string newUrl = build.ToString(); Retrieve the fully qualified URL without a QueryString AFAIK, there’s no native routine to retrieve the current request URL without the query string. It’s easy to do with UriBuilder however: UriBuilder builder = newUriBuilder(Request.Url); builder.Query = ""; stringlogicalPathWithoutQuery = builder.ToString();
