现在我已经过到Visual Studio 2010 Beta 2的

I have now gone over to Visual Studio 2010 Beta 2

I have used it for a few days, but now I can no longer add references from the GAC.

抱歉，因为这不是一个直接的发展问题，但我不知道在哪里问。

Sorry since this is not directly a development question, but I was not sure where to ask.

是否有人知道如何解决这个问题？

Does someone know how to fix this?

推荐答案

检查全局程序集缓存。你可能已经做了非常非常糟糕。

Check the Global Assembly Cache. You may have done something very very bad.

修改

我注意到你正在使用Silverlight的：

I noticed you are using Silverlight:

C：\ Program Files文件\参考大会\微软\框架\ Silverlight的\ V4.0

C:\Program Files\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0

我找不到Microsoft.CSharp.dll我只能找到Microsoft.VisualBasic.dll中使用。哪里是C＃DLL中寻找Silverlight 4的？我没能找到它在我的电脑上。

I cannot find the Microsoft.CSharp.dll I can only find Microsoft.VisualBasic.dll to use. Where is the C# dll located for Silverlight 4? I wasn’t able to find it on my computer.
