• Visual Studio, .NET Framework, and language versions

  - by Scott Dorman

  Every so often a question comes up about how Visual Studio, the .NET Framework, and a .NET programming language relate to each other. Mostly, these questions have to do with versions. The reality is that these are actually three different “products” that are versioned independently of each other but are related. Looking at how Visual Studio, the .NET Framework version, and the CLR versions relate to each other results in the following: Visual Studio CLR .NET Framework Visual Studio .NET (Ranier) 1.0.3705 1.0 Visual Studio 2003 (Everett) 1.1.4322 1.1 Visual Studio 2005 (Whidbey) 2.0.50727 2.0 Visual Studio 2005 with .NET 3.0 Extensions 2.0.50727 2.0, 3.0 Visual Studio 2008 (Orcas) 2.0.50727 2.0 SP1, 3.0 SP1, 3.5 Visual Studio 2008 SP1 2.0.50727 2.0 SP2, 3.0 SP2, 3.5 SP1 Visual Studio 2010 (Hawaii) 4.0.30319 4.0 The actual Visual Studio version numbers are: Product Name Version Ship Date Visual Studio .NET 7.0.???? 02/2002 Visual Studio .NET 2002 SP1 7.0.????   Visual Studio 2003 7.1.???? 04/2003 Visual Studio 2003 SP1 7.1.6030 09/13/2006 Visual Studio 2005 8.0.5072   Visual Studio 2005 SP1   12/14/2006 Visual Studio 2008 9.0.21022.8 11/19/2007 Visual Studio 2008 SP1 9.0.30729.1   Visual Studio 2010 10.0.30319.1 04/12/2010 (For those entries that are missing information, it simply means that I didn’t already know it and/or couldn’t easily find it online.) So far, everything seems fairly reasonable and isn’t terribly difficult to keep coordinated. However, when you start trying to find language versions and how those relate to .NET Framework, CLR, or Visual Studio releases it becomes more difficult. The breakdown for the programming languages that are part of Visual Studio are: Framework CLR Language     C# VB F# 1.0 1.0.3705 1.0 7.0 - 1.1 1.1.4322 1.1 7.1 - 2.0 2.0.50727 2.0 8.0 - 3.0 2.0.50727 2.0 8.0 - 3.5 2.0.50727 2.0 9.0 - 4.0 4.0.30319 4.0 10.0 2.0   Technorati Tags: Visual Studio,.NET

• what are the benefits of closure, primarily for PHP?

  - by Patrick

  I am beginning the process of moving code over to PHP 5.3 and one of the most highly touted features of PHP 5.3 is the ability to use closures. My understanding of closures is that they allow anonymous functions, can be assigned to variable names, and have interesting scoping abilities. From my point of view the only seeming benefits in real world applications is the reduction of clutter in the namespace because closures are anonymous. Am I wrong in this? Should I be trying to put closures wherever I code? EDIT: I have already read this post on Javascript closures.

• USA keyboard layout keeps getting added on login

  - by Scott Severance

  I use the USA International keyboard layout. Every time I log in, the USA layout gets added to my list of layouts, which causes the keyboard layout indicator to be displayed. How can I stop the USA layout from being added? Additional info: I'm running Natty. Until recently, I had all four layout slots filled. Recently I changed from SCIM to iBus. With this change, I no longer need multiple layouts since iBus better handles my needs. So, I don't want both indicators (iBus and Keyboard layout) showing up.

• NDepend 4 – First Steps

  - by Ricardo Peres

  Introduction Thanks to Patrick Smacchia I had the chance to test NDepend 4. I can only say: awesome! This will be the first of a series of posts on NDepend, where I will talk about my discoveries. Keep in mind that I am just starting to use it, so more experienced users may find these too basic, I just hope I don’t say anything foolish! I must say that I am in no way affiliated with NDepend and I never actually met Patrick. Installation No installation program – a curious decision, I’m not against it -, just unzip the files to a folder and run the executable. It will optionally register itself with Visual Studio 2008, 2010 and 11 as well as RedGate’s Reflector; also, it automatically looks for updates. NDepend can either be used as a stand-alone program (with or without a GUI) or from within Visual Studio or Reflector. Getting Started One thing that really pleases me is the Getting Started section of the stand-alone, with links to pages on NDepend’s web site, featuring detailed explanations, which usually include screenshots and small videos (<5 minutes). There’s also an How do I with hierarchical navigation that guides us to through the major features so that we can easily find what we want. Usage There are two basic ways to use NDepend: Analyze .NET solutions, projects or assemblies; Compare two versions of the same assembly. I have so far not used NDepend to compare assemblies, so I will first talk about the first option. After selecting a solution and some of its projects, it generates a single HTML page with an highly detailed report of the analysis it produced. This includes some metrics such as number of lines of code, IL instructions, comments, types, methods and properties, the calculation of the cyclomatic complexity, coupling and lots of others indicators, typically grouped by type, namespace and assembly. The HTML also includes some nice diagrams depicting assembly dependencies, type and method relative proportions (according to the number of IL instructions, I guess) and assembly analysis relating to abstractness and stability. Useful, I would say. Then there’s the rules; NDepend tests the target assemblies against a set of more than 120 rules, grouped in categories Code Quality, Object Oriented Design, Design, Architecture and Layering, Dead Code, Visibility, Naming Conventions, Source Files Organization and .NET Framework Usage. The full list can be configured on the application, and an explanation of each rule can be found on the web site. Rules can be validated, violated and violated in a critical manner, and the HTML will contain the violated rules, their queries – more on this later - and results. The HTML uses some nice JavaScript effects, which allow paging and sorting of tables, so its nice to use. Similar to the rules, there are some queries that display results for a number (about 200) questions grouped as Object Oriented Design, API Breaking Changes (for assembly version comparison), Code Diff Summary (also for version comparison) and Dead Code. The difference between queries and rules is that queries are not classified as passes, violated or critically violated, just present results. The queries and rules are expressed through CQLinq, which is a very powerful LINQ derivative specific to code analysis. All of the included rules and queries can be enabled or disabled and new ones can be added, with intellisense to help. Besides the HTML report file, the NDepend application can be used to explore all analysis results, compare different versions of analysis reports and to run custom queries. Comparison to Other Analysis Tools Unlike StyleCop, NDepend only works with assemblies, not source code, so you can’t expect it to be able to enforce brackets placement, for example. It is more similar to FxCop, but you don’t have the option to analyze at the IL level, that is, other that the number of IL instructions and the complexity. What’s Next In the next days I’ll continue my exploration with a real-life test case. References The NDepend web site is http://www.ndepend.com/. Patrick keeps an updated blog on http://codebetter.com/patricksmacchia/ and he regularly monitors StackOverflow for questions tagged NDepend, which you can find on http://stackoverflow.com/questions/tagged/ndepend. The default list of CQLinq rules, queries and statistics can be found at http://www.ndepend.com/DefaultRules/webframe.html. The syntax itself is described at http://www.ndepend.com/Doc_CQLinq_Syntax.aspx and its features at http://www.ndepend.com/Doc_CQLinq_Features.aspx.

• General input/output error on OpenOffice 3.2

  - by Scott

  I have been working on a research paper in OpenOffice 3.2 Word Processor and I had a slide show OpenOffice 3.2 Presentation. I saved both frequently and they were not very big (no more then 5 pages of text or a few slides). A few days after I last edited and saved them, I tried to open the slide show but I received window saying: General Error. General input/output error When I tried opening the paper, it asked for ASCII Filter Options (font, character, language, and paragraph break). When I set the normal settings, a single blank document opened with nothing on it. I looked at both of the file's properties and the size was 0 or 1.5 KB, and the volume was unknown. I recently installed some updates for Ubuntu 10.10 and everything else in my computer is working normally including other documents and slide shows. Is this a fixable crash?

• How to prevent Google Website Optimizer from making Google Analytics spike Direct Traffic and lower Bounce Rate?

  - by Scott

  I am using Google Website Optimizer (GWO) and Google Analytics. Whenever a person (Google Website Optimizer) does a javascript redirect, Google Analytics will change the referrer. When the referrer changes, the traffic source becomes yourself and is changed to Direct Traffic. For Example: A visitor goes to google: searches for my great service. Clicks the link that goes to website page: /home/ At this point, Google Analytics tracks the referrer as Google. However, /home/ has a GWO javacript redirect to a battery of A/B tests. /home-1/ or /home-2/ or /home-3/ When the redirect from /home/ occurs to /home-1/, google analytics on the /home-1/ page now thinks the referrer is yourself and converts the referrer to Direct Traffic since the Direct Traffic bucket is the unknown. I'm really surprised that GWO and GA do this when they both come from google. Now, How does one fix this to prevent the overwrite of the referrer using GWO?

• Visual Studio 2010 and Target Framework Version

  - by Scott Dorman

  Almost two years ago, I wrote about a Visual Studio macro that allows you to change the Target Framework version of all projects in a solution. If you don’t know, the Target Framework version is what tells the compiler which version of the .NET Framework to compile against (more information is available here) and can be set to one of the following values: .NET Framework 2.0 .NET Framework 3.0 .NET Framework 3.5 .NET Framework 3.5 Client Profile .NET Framework 4.0 .NET Framework 4.0 Client Profile This can be easily accomplished by editing the project properties: The problem with this approach is that if you need to change a lot of projects at one time it becomes rather unwieldy. One possible solution is to edit the project files by hand in a text editor and change the <TargetFrameworkVersion /> and <TargetFrameworkProfile /> properties to the correct values. For example, for the .NET Framework 4.0 Client Profile, these values would be: <TargetFrameworkVersion>v4.0</TargetFrameworkVersion> <TargetFrameworkProfile>Client</TargetFrameworkProfile> Again, this is not only time consuming but can also be error-prone. The better solution is to automate this through the use of a Visual Studio macro. Since I had already created a macro to do this for Visual Studio 2008, I updated that macro to work with Visual Studio 2010 and .NET 4.0. It prompts you for the target framework version you want to set for all of the projects and then loops through each project in the solution and makes the change. If you select one of the Framework versions that support a Client Profile, it will ask if you want to use the Client Profile or the Full Profile. It is smart enough to skip project types that don’t support this property and projects that are already at the correct version. This version also incorporates the changes suggested by George (in the comments). The macro is available on my SkyDrive account. Download it to your <UserProfile>\Documents\Visual Studio 2010\Projects\VSMacros80\MyMacros folder, open the Visual Studio Macro IDE (Alt-F11) and add it as an existing item to the “MyMacros” project. I make no guarantees or warranties on this macro. I have tested it on several solutions and projects and everything seems to work and not cause any problems, but, as always, use with caution. Since it is a macro, you have the full source code available to investigate and see what it’s actually doing. If you find any bugs or make any useful changes, please let me know and I’ll update the macro. Technorati Tags: Macros,Visual Studio

• Announcing: Oracle Enterprise Manager 12c Delivers Advanced Self-Service Automation for Oracle Database 12c Multitenant

  - by Scott McNeil

  New Self-Service Driven Provisioning of Pluggable Databases Today Oracle announced new capabilities that support managing the full lifecycle of pluggable database as a service in Oracle Enterprise Manager 12c Release 3 (12.1.0.3). This latest release builds on the existing capabilities to provide advanced automation for deploying database as a service using Oracle Database 12c Multitenant option. It takes it one step further by offering pluggable database as a service through Oracle Enterprise Manager 12c self-service portal providing customers with fast provisioning of database cloud services with minimal time and effort. This is a significant addition to Oracle Enterprise Manager 12c’s existing portfolio of cloud services that includes infrastructure as a service, database as a service, testing as a service, and Java platform as a service. The solution provides a self-service mechanism to provision pluggable databases allowing users to request and access database(s) on-demand. The self-service operations are also enabled through REST APIs allowing customers to integrate with third-party automation systems or their custom enterprise portals. Benefits Self-service provisioning allows rapid access to pluggable database as a service for hosting or certifying applications on Oracle Database 12c Self-service driven migration to pluggable database as a service in order to migrate a pre-Oracle Database 12c database to a pluggable database as a service model and test the consolidation strategy Single service catalog for all approved pluggable database as a service configurations which helps customers achieve standardization while catering to all applications and users in the enterprise Resource guarantee via database resource manager (and IORM on Oracle Exadata) that enables deployment of mixed workloads in a shared environment Quota, role based access, and policy based management that enforces governance and reduces administrative overhead Chargeback or showback which improves metering and accountability for services consumed by each pluggable database Comprehensive REST APIs that support integration with ticketing or change management systems, and or with other self-service portals Minimal administrative and maintenance overhead through self-managing automation that allows for intelligent placement of pluggable databases To understand how pluggable database as a service works, watch this quick demo: Stay Connected: Twitter | Facebook | YouTube | Linkedin | Newsletter Download the Oracle Enterprise Manager Cloud Control12c Mobile app

• I Admit I Misspoke

  - by Patrick Liekhus

  OK.  I admit it.  The last post I hade mentioned that we moved the XAF DSL to the Entity Framework.  This has caused a lot of confusion.  I meant to say that we have used the ADO.NET Entity Data Model extensions.  This is the design surface that can be tailored to create Entity Framework. We leveraged the code generation within the ADO.NET Entity Data Model (EDMX) file to generate XAF/XPO classes.  This allows you to visually create the entity model, set a few XAF properties and then generate the business objects from there.  I am presenting all these topics at the Kansas City Developers Conference on June 19th.  I will post the presentation after the conference.  I have a full presentation that will demonstrate the power of the ADO.NET Entity Data Model extensions, create a small project and then add the OData layer to XAF to connect to the PowerPivot in Excel 2010. The latest code can be found at http://efxaf.codeplex.com. More details to come soon.  Sorry for the confusion in the last post. Thanks again.

• Highly recommended: "5 Things SQL Server does different from what many developers expect" by Nico Ja

  A couple of weeks ago, the Belgian Techdays were held in Antwerp. Together with Scott Hillier I presented the SharePoint pre-conference sessions (watch them online over here, search for pre-conference or SharePoint). Even though Belgium is not a very big country, the Microsoft team managed to get some high profile speakers like Anders Hejlsberg and Scott Hanselman. But if you have like 60 minutes to spare there is one session that I'd really recommend to check out, not related to SharePoint, but...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Developing professionally for iOS, Android and web - an insight

  - by Scott Roberts

  This is not really a question on how to develop all three, I know various cross platform ways and so on. But I more want to know from developer standpoint how hard it is to basically develop iOS, Android and web apps? I am currently in my first job as a mobile/web developer. I have already developed my first iPhone/iPad app and now I have to develop the app for android because the web version I tried just didn't perform as well as needed and web databases just did not seem to make the cut. But I am not sure it's possible to be good at developing all 3 in terms of remembering all the api's etc. I wouldn't say I have an issue with the programming languages just how to use the api's for the various platforms. Also, all the other languages I look at, in my spare time, just feel like I am spreading myself to thin. Is it feasible for one person to be developing ios, android and web apps? Should I think about reducing it to iOS and web based apps? I develop everything by myself, so I have no one to discuss what the best solutions are for everything and I am just trying to workout as I go along. So any cross platform developers out there? Do companies have different teams for different platforms? Any insight would just help me get my head together. Hopefully this question makes sense.

• Designing a Content-Based ETL Process with .NET and SFDC

  - by Patrick

  As my firm makes the transition to using SFDC as our main operational system, we've spun together a couple of SFDC portals where we can post customer-specific documents to be viewed at will. As such, we've had the need for pseudo-ETL applications to be implemented that are able to extract metadata from the documents our analysts generate internally (most are industry-standard PDFs, XML, or MS Office formats) and place in networked "queue" folders. From there, our applications scoop of the queued documents and upload them to the appropriate SFDC CRM Content Library along with some select pieces of metadata. I've mostly used DbAmp to broker communication with SFDC (DbAmp is a Linked Server provider that allows you to use SQL conventions to interact with your SFDC Org data). I've been able to create [console] applications in C# that work pretty well, and they're usually structured something like this: static void Main() { // Load parameters from app.config. // Get documents from queue. var files = someInterface.GetFiles(someFilterOrRegexPattern); foreach (var file in files) { // Extract metadata from the file. // Validate some attributes of the file; add any validation errors to an in-memory // structure (e.g. List<ValidationErrors>). if (isValid) { var fileData = File.ReadAllBytes(file); // Upload using some wrapper for an ORM or DAL someInterface.Upload(fileData, meta.Param1, meta.Param2, ...); } else { // Bounce the file } } // Report any validation errors (via message bus or SMTP or some such). } And that's pretty much it. Most of the time I wrap all these operations in a "Worker" class that takes the needed interfaces as constructor parameters. This approach has worked reasonably well, but I just get this feeling in my gut that there's something awful about it and would love some feedback. Is writing an ETL process as a C# Console app a bad idea? I'm also wondering if there are some design patterns that would be useful in this scenario that I'm clearly overlooking. Thanks in advance!

• Backtick (Grave accent) button sticking

  - by Scott Lemmon

  I have Ubuntu 12.04 running in a Virtual Box virtual machine, on my Windows 7 32bit system. It has been working great, except that the backtick/tilde button sticks(not physically). When I hit the backtick button it keeps repeating until another input button is pressed. So if I press the spacebar while the backtick is repeating, it stops, but if I press the shift while it is repeating, the backtick turns into a tilde, and the tilde keeps repeating until I release the shift key (at which point it's a backtick again and keeps repeating). This sticking behavior only happens with the backtick key, and only in my Ubuntu virtualization, never in windows. I've tried both my laptop's keyboard and an external USB keyboard and the problem happens on both. Both keyboards I've tried are Japanese 106/109 key layout, but I'm using them with a English(US) 101 profile. When I refer to the backtick key above, I mean where it is on the US layout. If I use the Japanese profile, the key in that location (the US backtick location) still sticks, but its no longer mapped as the backtick key. Any thoughts as to what might be causing this and possible solutions? I've searched a lot, but have not found any help so far. Any help is greatly appreciated.

• Wolfram is out, any alternatives? Or how to go custom?

  - by Patrick

  We were originally planning on using wolfram alpha api for a new project but unfortunately the cost was entirely way to high for what we were using it for. Essentially what we were doing is calculating the nutrition facts for food. (http://www.wolframalpha.com/input/?i=chicken+breast+with+broccoli). Before taking the step of trying to build something that may work in its place for this use case is there any open source code anywhere that can do this kind of analysis and compile the data? The hardest part in my opinion is what it has for assumptions and where it gets that data to power the calculations. Or another way to put it is, I cannot seem to wrap my head around building something that computes user input to return facts and knowledge. I know if I can convert the user input into some standardized form I can then compare that to a nutrition fact database to pull in the information I need. Does anyone know of any solutions to re-create this or APIs that can provide this kind of analysis? Thanks for any advice. I am trying to figure out if this project is dead in the water before it even starts. This kind of programming is well beyond me so I can only hope for an API, open source, or some kind of analysis engine to interpret user input when I know what kind of data they are entering (measurements and food).

• Work Item Traceability in TFS 2010

  - by Sam Patrick

  I have created a Windows Form project (VS solution) under a TFS 2010 project. I may eventually add more solutions to the TFS project. My question: Can we create a Use Case WIT for a specific solution within a TFS project? Furthermore, is it possible to create a "traceability matrix" that starts at the Use Case level and goes down to the the code level (at least the namespace level) of that particular VS solution?
