vs 2010 beta2 出来很长时间了，一直没有时间尝试，今天下载了安装文件，安装时提示我必须先卸载原来安装的beta1版之后才能安装beta2版，可是卸载beta1时又提示我要插入安装盘才能继续，当时为了节约空间，在安装完之后就把安装文件删除了，难道我还要重新下载beat1的安装盘？这也太……

于是上网Google，找到了一篇说明，卸载步骤如下：

Here's technical details on how to uninstall VS 2010 Beta 1 and .NET 4 Beta 1:

1. Uninstall TFS Object Model (This step is Visual Studio 2010 Team Suite only)

2. 2. Uninstall Visual Studio 2010 Beta 1
   1. From Add/Remove, uninstall all instances of Visual Studio 2010 (Team, Pro, etc. You likely have just one, but one can't be sure.)
   2. Be sure to see the Visual Studio Setup wizard through to completion.
3. 3. Uninstall .NET Framework 4 Beta 1
   1. From Add/Remove, uninstall in this order:
      1. Microsoft .NET Framework 4 Extended Beta 1 - Language Pack
