我正在尝试使用Visual Studio 2010 Ultimate打开VS 2010项目。该项目受源代码管理（TFS），我想从本地文件夹中打开它。打开后，我收到一个错误：
The Project is under Source Control. This Version of Visual studio .net does
not support source controlled projects. Any changes that you make to this project
will not be propagated to source code.
然后是消息
Exception details:
System.Runtime.InteropServices.COMException (0x80004005): Package 'Microsoft.VisualStudio.TeamFoundation.VersionControl.HatPackage, Microsoft.VisualStudio.TeamFoundation.VersionControl, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' failed to load.

at System.Runtime.InteropServices.Marshal.ThrowExceptionForHR(Int32 errorCode)
at Microsoft.VisualStudio.Platform.WindowManagement.WindowFrame.GetPackage()
at Microsoft.VisualStudio.Platform.WindowManagement.WindowFrame.ConstructContent()
然后，解决方案显示一个不可用的项目。我不认为它可能是一个版本问题，因为我使用VS Ultimate。关于这个问题已经有question，但我无法做出很多答案
