我无法在Visual Studio 2012 RC中创建或打开单元测试项目

Question

在Visual Studio 2012 RC中打开或创建单元测试项目时，我一直遇到错误。我在哪里可以找到有关如何解决此问题的答案。我尝试过多次维修。我尝试过卸载并重新安装。我删除了产品附带的所有扩展（NuGet）。任何帮助修复这个bug或找到我可以获得帮助的地方都是受欢迎的。

The 'Microsoft.VisualStudio.TestTools.Tips.TuipPackage.TuipPackage, Microsoft.VisualStudio.QualityTools.Tips.TuipPackage, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' package did not load correctly.

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\Me\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml'.

我相信这是该档案的相关部分：

Answer 1

我停止收到错误消息的方法是删除.sln文件中的以下与此类似的部分：

ProjectSection(SolutionItems) = preProject
    SomeName.vsmdi = SomeName.vsmdi
    Local.testsettings = Local.testsettings
    TraceAndTestImpact.testsettings = TraceAndTestImpact.testsettings
EndProjectSection

和此：

GlobalSection(TestCaseManagementSettings) = postSolution
    CategoryFile = SomeName.vsmdi
EndGlobalSection

Answer 2

遇到同样的问题，我从2010年到2012年删除了有关visual studio的所有内容，重新启动并重新安装了2012 RC并检查了所有选项。它现在有效。
