我遇到以下问题：
尝试添加对Silverlight 5应用程序（[MSDN] [1]）的编码UI测试的支持。第一步是在Silverlight 5项目中引用程序集Microsoft.VisualStudio.TestTools.UITest.Extension.SilverlightUIAutomationHelper.dll。不幸的是，在添加引用之后，项目停止编译时出现了许多类似的错误：
＆GT;
Error 25 Cannot resolve reference assemblies. Please check the reference assemblies. Could not load file or assembly 'System.Core, Version=5.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) ....\ErrorReportDialog.xaml
Looks like System.Core 5.0.5.0 fails to load, okay, debugging assemblies loading with Fuslogw produces two interesting logs:
First log:
> Assembly Binder Log Entry (04.03.2013 @ 14:07:49)
The operation was successful.
Bind result: hr = 0x0. The operation completed successfully.
Assembly manager loaded from: C:\Windows\Microsoft.NET\Framework\v4.0.30319\clr.dll
Running under executable C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe
A detailed error log follows.

Looks like System.Core, Version=5.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e loads succesfully.
But second log entry produces the following error:

The operation failed.
Bind result: hr = 0x80131040. No description available.

看起来像Microsoft.VisualStudio.TestTools.UITest.Extension.SilverlightUIAutomationHelper.dll尝试加载System.Core，Version = 2.0.5.0，Culture = neutral，PublicKeyToken = 7cec85d7bea7798e，但正被重定向到System.Core，Version = 5.0.5.0，Culture = neutral，PublicKeyToken = 7cec85d7bea7798e（已从第1个日志加载）仍然无法加载。
Can anyone provide some insight on how to further debug this problem? I'm compiling Silverlight projects for AnyCpu platform.
