This looks a little different from those others I've seen. Here is the output: Error 1 The "ValidateXaml" task failed unexpectedly. System.ArgumentNullException: Parameter "message" error 1 cannot be null. at Microsoft.Build.Shared.ErrorUtilities.VerifyThrowArgumentNull(Object parameter, String parameterName) at Microsoft.Build.Utilities.TaskLoggingHelper.LogError(String subcategory, String errorCode, String helpKeyword, String file, Int32 lineNumber, Int32 columnNumber, Int32 endLineNumber, Int32 endColumnNumber, String message, Object[] messageArgs) at Microsoft.Build.Utilities.TaskLoggingHelper.LogError(String message, Object[] messageArgs) at Microsoft.Build.Utilities.TaskLoggingHelper.LogError(String message, Object[] messageArgs) at Microsoft.Silverlight.Build.Tasks.ValidateXaml.XamlValidator.Execute() at Microsoft.Silverlight.Build.Tasks.ValidateXaml.XamlValidator.Execute() at error 1 the Microsoft.Silverlight.Build.Tasks.ValidateXaml.Execute() at Microsoft.Build.BuildEngine.TaskEngine.ExecuteInstantiatedTask(EngineProxy engineProxy, ItemBucket bucket, TaskExecutionMode howToExecuteTask, ITask task, Boolean& taskResult) OnlineClient.Test From the stack trace, it looks like a problem gets suppressed by a failure trying to report it. The scenario is that I have two Silverlight application projects: the actual application I'm developing and a unit test application (using the Silverlight Toolkit test framework). There is also a class library project that the main app uses. As soon as I try to add a reference to the class library in my test application and try to build, I get the above error. If I remove the reference, all is well again. If I disable XAML validation by setting the proprty in the project file to false, the test project builds and runs fine. This kind of seems like a bug (though with a work-around). Friday, July 24, 2009 11:38 AM Reply | Quote All replies 0 Sign
10, 2008 by Ezequiel Jadib 4Last week I've installed Microsoft Silverlight Tools 2 Beta 2 on my laptop to start developing applications for Silverlight 2 Beta 2.Once the installation finish, I created a Silverlight Application just to see if everything works as expected. The application was successfully created but when I tried to build and run the solution, I faced with the following error:
After spend some time searching for some clues, I found the following solution:Open the Visual Studio 2008 Command Prompt.Executedevenv /ResetSkipPkgs in the command prompt. This switch clears all options to skip loading added to VSPackages by users wishing to avoid loading problem VSPackages. This switch also starts Visual Studio.Close Visual Studio and then execute devenv /Setup in the command prompt. This switch forces Visual Studio to merge the resource metadata that describes menus, toolbars, and command groups from all VSPackages availableOpen Visual Studio and have fun.For more information about the Devenv Command Line Switches, see Devenv Command Line Switches on MSDN.Hope this helps.
