  • Moving to .net 4 results in System.Transactions Critical: 0

    - by john
    Hi I have fully working project in .net 3.5SP1, with EF 1 ORM. I tried to upgrade to .net 4. No issue while upgrading... Then i ran the project and got a NullExecptionError, with no stack trace... and no way to debug. Looking at the output windows i can read this: System.Transactions Critical: 0 : <TraceRecord xmlns="http://schemas.microsoft.com/2004/10/E2ETraceEvent/TraceRecord" Severity="Critical"><TraceIdentifier>http://msdn.microsoft.com/TraceCodes/System/ActivityTracing/2004/07/Reliability/Exception/Unhandled</TraceIdentifier><Description>Unhandled exception</Description><AppDomain>OTCSouscriptions.vshost.exe</AppDomain><Exception><ExceptionType>System.NullReferenceException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType><Message>Object reference not set to an instance of an object.</Message><StackTrace> at System.Windows.StyleHelper.GetInstanceValue(UncommonField`1 dataField, DependencyObject container, FrameworkElement feChild, FrameworkContentElement fceChild, Int32 childIndex, DependencyProperty dp, Int32 i, EffectiveValueEntry&amp;amp; entry) at System.Windows.FrameworkTemplate.ReceivePropertySet(Object targetObject, XamlMember member, Object value, DependencyObject templatedParent) at System.Windows.FrameworkTemplate.&amp;lt;&amp;gt;c__DisplayClass6.&amp;lt;LoadOptimizedTemplateContent&amp;gt;b__4(Object sender, XamlSetValueEventArgs setArgs) at System.Xaml.XamlObjectWriter.OnSetValue(Object eventSender, XamlMember member, Object value) at System.Xaml.XamlObjectWriter.Logic_ApplyPropertyValue(ObjectWriterContext ctx, XamlMember prop, Object value, Boolean onParent) at System.Xaml.XamlObjectWriter.Logic_DoAssignmentToParentProperty(ObjectWriterContext ctx) at System.Xaml.XamlObjectWriter.Logic_AssignProvidedValue(ObjectWriterContext ctx) at System.Xaml.XamlObjectWriter.WriteEndObject() at System.Xaml.XamlWriter.WriteNode(XamlReader reader) at System.Windows.FrameworkTemplate.LoadTemplateXaml(XamlReader templateReader, XamlObjectWriter currentWriter) Any help appreciated...

  • Visual Studio 2010 Productivity Power Tool Extensions

    Last month I blogged about the Extension Manager that is built-into VS 2010 as well as about a cool VS 2010 PowerCommands extension that provides some extra features for Visual Studio.  The Visual Studio 2010 Extension Manager provides an easy way for developers to quickly find and install extensions and plugins that enhance the built-in functionality to VS 2010. New VS 2010 Productivity Power Tools Release Earlier this week Jason Zander announced the availability of a new VS 2010...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Download and Share Visual Studio Color Schemes

    As developers we often spend a large part of our day staring at code within Visual Studio.  If you are like me, after awhile the default VS text color scheme starts to get a little boring. The good news is that Visual Studio allows you to completely customize the editor background and text colors to whatever you want allowing you to tweak them to create the experience that is just right for your eyes and personality.  You can then optionally export/import your color scheme preferences...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Error: The base type 'System.Web.UI.MasterPage' is not allowed for this page

    - by Patrick Olurotimi Ige
    I came across this error when i was trying to ajaxify my sharepoint site. After adding the AjaxifyMoss from the codeplex  developed by Richard Finn. And tried loading my site i got the error Error: The base type 'System.Web.UI.MasterPage' is not allowed for this page So  i decided to check the web.config and i noticed the SafeControl tag doesn't have the .Net 2.0 assembly included despite the fact i added both vsersios 2.0 and 3.5. Its possible the.Net  3.5 assebply overwrote the 2.0. Anyway after i added the below which is the 2.0 verison       <SafeControl Assembly="System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="System.Web.UI" TypeName="*" Safe="True" AllowRemoteDesigner="True" />  And refreshed my page. It worked

  • Programmatically use a server as the Build Server for multiple Project Collections

    Important: With this post you create an unsupported scenario by Microsoft. It will break your support for this server with Microsoft. So handle with care. I am the administrator an a TFS environment with a lot of Project Collections. In the supported configuration of Microsoft 2010 you need one Build Controller per Project Collection, and it is not supported to have multiple Build Controllers installed. Jim Lamb created a post how you can modify your system to change this behaviour. But since I have so many Project Collections, I automated this with the API of TFS. When you install a new build server via the UI, you do the following steps Register the build service (with this you hook the windows server into the build server environment) Add a new build controller Add a new build agent So in pseudo code, the code would look like foreach (projectCollection in GetAllProjectCollections) {       CreateNewWindowsService();       RegisterService();       AddNewController();       AddNewAgent(); } The following code fragements show you the most important parts of the method implementations. Attached is the full project. CreateNewWindowsService We create a new windows service with the SC command via the Diagnostics.Process class:             var pi = new ProcessStartInfo("sc.exe")                         {                             Arguments =                                 string.Format(                                     "create \"{0}\" start= auto binpath= \"C:\\Program Files\\Microsoft Team Foundation Server 2010\\Tools\\TfsBuildServiceHost.exe              /NamedInstance:{0}\" DisplayName= \"Visual Studio Team Foundation Build Service Host ({1})\"",                                     serviceHostName, tpcName)                         };            Process.Start(pi);             pi.Arguments = string.Format("failure {0} reset= 86400 actions= restart/60000", serviceHostName);            Process.Start(pi); RegisterService The trick in this method is that we set the NamedInstance static property. This property is Internal, so we need to set it through reflection. To get information on these you need nice Microsoft friends and the .Net reflector .             // Indicate which build service host instance we are using            typeof(BuildServiceHostUtilities).Assembly.GetType("Microsoft.TeamFoundation.Build.Config.BuildServiceHostProcess").InvokeMember("NamedInstance",              System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.SetProperty | System.Reflection.BindingFlags.Static, null, null, new object[] { serviceName });             // Create the build service host            serviceHost = buildServer.CreateBuildServiceHost(serviceName, endPoint);            serviceHost.Save();             // Register the build service host            BuildServiceHostUtilities.Register(serviceHost, user, password); AddNewController and AddNewAgent Once you have the BuildServerHost, the rest is pretty straightforward. There are methods on the BuildServerHost to modify the controllers and the agents                 controller = serviceHost.CreateBuildController(controllerName);                 agent = controller.ServiceHost.CreateBuildAgent(agentName, buildDirectory, controller);                controller.AddBuildAgent(agent); You have now seen the highlights of the application. If you need it and want to have sample information when you work in this area, download the app TFS2010_RegisterBuildServerToTPCs

  • Visual Studio IntelliSense for URL Rewrite

    Visual Studio doesnt have IntelliSense support for URL Rewrite by default.  This isnt a show stopper since it doesnt result in stop errors. However, its nice to have full IntelliSense support and to get rid of the warnings for URL Rewrite rules. RuslanY has released a Visual Studio schema update for URL Rewrite which is available as a free quick download.  Contrary to the title of the post, the installer is for both URL Rewrite 1.1 and 2.0.  The install takes effect immediately...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

    SharePoint 2010 Training: more information My newest article is now online. This article talks about the specific improvements in Visual Studio 2011 for SharePoint 2010 development.

All the new improvements will benefit your SP development, for instance, they finally fixed that add-references annoying as crap dialog box. Anyway, this article talks specifically about SP2010 development improvements, so I hope you like it. The article Read full article ....

  • The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration

    - by Jeff Widmer
    After upgrading an ASP.NET application from .NET Framework 3.5 to .NET Framework 4.0 I ran into the following error message dialog when trying to view any of the modules in IIS on the server. What happened is during the upgrade, the web.config file was automatically converted for .NET Framework 4.0.  This left behind an empty system.web.extensions section: It was an easy fix to resolve, just remove the unused system.web.extensions section.   ERROR DIALOG TEXT: --------------------------- ASP --------------------------- There was an error while performing this operation. Details: Filename: \\?\web.config Line number: 171 Error: The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration --------------------------- OK   ---------------------------

  • The .NET Rocks! Visual Studio 2010 Road Trip

    - by Laila
    Carl Franklin and Richard Campbell, the two .NET Rocks radio show hosts, have decided to set off to 15 cities in the US, between April 19th and May 7th, in their DotNetMobile (a 30 foot RV). What for you'll ask me? Well, to drive around the US, meet up with .NET developers, and show off the latest and greatest in Visual Studio 2010 and .NET 4.0! Each evening, they stop in a city and host a three hour event in front of a 100 to 300 crowd of developers, where Carl is showing off media features in Silverlight 4 and their road trip tracking application, whilst Richard is demo-ing the web performance testing features of VS2010 using his portable server rig. But before they take to the stage, they have a special guest brought in - a rock star from the Visual Studio world - whom they interview for an hour as a .NET Rock episode. So far, they've had - amongst others - Phil Haack, a Program Manager with the ASP.NET team working on ASP.NET MVC, Dan Fernandez, an Evangelism Manager in the Developer and Platform Evangelism team at Microsoft, and Beth Massi, Senior Program Manager on the Visual Studio Community Team at Microsoft. I love the fact that the audience gets a chance to participate, ask questions and have a great laugh, as you can hear in the first episode! Along the way, the .NET Rocks guys are giving away great prizes (including .NET Reflector Pro, ANTS Memory Profiler licenses, and "40" LCD TVs!). Even more out of the ordinary, at each stop on the road trip, one lucky attendee (who entered in the Ride Along competition) gets to jump in the RV with Carl and Richard and ride along with them to the next stop on the roadtrip. How cool is that! Richard told us: "Our first winner in Mountain View was Eric Ziko. I was looking for him to announce that he had won, when he found us and gave us a bottle of scotch he had brought just to say 'thanks for the great show'. We all had a toast from the bottle the next night when he headed back home." Cheeky! There's still space to a few of these events, so if you want to attend, register now, because it's first come first serve. We're grateful to Richard and Carl for giving us the opportunity to sponsor this major .NET event! A unique .NET adventure worth following for sure. Cheers, Laila

  • Application Lifecycle Management with Visual Studio 2010 – Wrox Book

    - by Guy Harwood
    After running with a somewhat disconnected set of tools (vs 2008, Ontime, sharepoint 2007) for managing our projects we decided to make the move to Team Foundation Server 2010.  With limited coverage of the product available online i went in search of a book and found this… View this book on the Wrox website I must point out that i have only read 10 of the 26 chapters so far, mainly the ones that cover source code control, work item tracking and database projects.  This enables our dev team to get familiar with it before switching project management over at a future date. Needless to say i am very impressed with the detail it provides, answering pretty much every question i had about TFS so far.  I'm looking forward to digging into the sections on testing, code analysis and architecture. Highly recommended.

  • Can't install Visual Studio 2010 SP1 from an .ISO file I downloaded. Error inside

    - by Sergio
    This is the error: [Window Title] C:\Users\Sergio\Desktop\Things\Setup.exe [Content] The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher. [OK] I'm running Windows 7 (64bit) Ultimate and have installed this service pack before (2 days ago) on another machine with similar specs and the same exact OS software. I've tried mounting the .ISO file to a virtual drive and installing from there and I get that error. I've tried mounting the .ISO and copy pasting the files to a local folder on my drive and then running the setup.exe application, and I get that error. I don't know how to proceed but can provide any additional information you require from me. What can I do to fix this? Edit If I right click Setup.exe and Run As Administrator, I get the following error: [Window Title] C:\Users\Sergio\Desktop\Things\Setup.exe [Content] Windows cannot find 'C:\Users\Sergio\Desktop\Things\Setup.exe'. Make sure you typed the name correctly, and then try again. [OK] I've already tried re downloading the ISO from the site, but a quick check of the bytes of the file assures me that the ISO on my drive is 100% correctly downloaded. I get the same amount of bytes in size from the downloading ISO (as Opera reports).

  • Running Unity 2d - Does not work on actual system but works fine in VM

    - by Dylan
    So I'm running Ubuntu 10.10 and I cannot get Unity 2d to work with my system. This is particularly frustrating as it works just fine in all the VMs I've tested it on. I actually really like Unity and I want to get to know it (in part) before Ubuntu 11.04. I checked Synaptic and it looks like everything's there. The only thing not installed are dev libs and so on. Should I install those as well? Obviously the difference between my system and a VM is that the VM is running off a basically brand new OS. I only use VMs to test new stuff out and remake them often, so my only guess is that I have something installed on my system that is preventing Unity from running. Any thoughts?

  • visual basic coach needed [closed]

    - by Danny
    0 down vote favorite I am trying to learn visual basic. I used to program in gw-basic and have trouble learning vb.net by reading and googling all the time. It takes so much time to find the answers to my programming problems and even then i do not understand the why it have to be done that way. I have beginners questions like finding childwindows using enumwindow. Then googling for hours and hours i do not seem to grasp it (must be my old age). I would like to get someone i could learn from by asking questions about what i want to program and learn from it. not to just finish the program but to learn and understand it too. Someone who dont find questions stupid to ask as i try to build my understanding of the visual basic environment. I hope to communicate by using skype voice or chat or other direct means when time permits it. Cheers, Danny

  • Visual Studio 2010 RC and Crystal Reports 2008 Just Works

    I have Crystal Reports 2008. This is the full application, not the Crystal Reports extension embedded into Visual Studio. This morning I pulled a solution with many projects and many crystal report files into Visual Studio 2010 for the first time. This application originated in VS2003, migrated to VS2005/.NET 2.0, migrated again to VS2008 (still .NET 2.0) and now migrated to VS2010 (still .NET 2.0). Wow everything is SO much faster working with this solution in VS2010. It loads up so quickly. It...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Multi-Device Development in Visual Studio

    - by Daniel Moth
    You've read on Soma's blog post that Microsoft is broadening Visual Studio's reach to other platforms (including for example Android)…  specifically this is what Soma wrote: "With bring-your-own-device trends in the enterprise, and heterogeneity in the consumer mobile device market, developers are increasingly focused on building apps that can target a variety of devices. We are committed to enabling developers to build apps for this heterogeneous, mobile-first world with Visual Studio for the technology of your choice - whether .NET, C++ or JavaScript." If you live in Washington state in the USA (or are willing to relocate here) I am looking for a Program Manager to help with this effort – read the rest of the job description here which is also where you can apply for the position (or email me).
