我安装VS.NET 2010 premium，但试图目标现有的.NET框架时看来是一个问题。当我打开一个Web应用程序项目的属性，我得到的唯一的选择就是安装一个框架。如果我打开属性，任何其他项目类型我得到的完整列表。

I have VS.NET 2010 Premium installed, but there seems to be an issue when trying to target existing .NET frameworks. When I open properties for a web application project, the only option I get is to install a framework. If I open properties for any other project type I get the full list.

到目前为止，我已经做了以下无济于事：

So far I've done the following to no avail:

• 在修复和重新安装Microsoft.NET Framework 4的客户端配置文件
• 在修复和重新安装Microsoft.NET Framework 4的扩展
• 在修复和重新安装Microsoft.NET Framework 4的多目标包
• 在修复和重新安装VS.NET 2010 premium
• 重新申请，重新安装VS.NET 2010 SP1。

我发现一个问题上似乎是相关的关系，但没有答案不幸。

I did find one question on that appear to be related related, but there were no answers unfortunately.

的Visual Studio 2010 [否目标框架＆QUOT;

任何想法？

推荐答案

我有过这样的问题，以及在多个不同的机器，并不得不在每次重新找到了答案！

I have had this issue as well across a number of different machines and have had to rediscover the answer each time!

这一直为我工作的解决方案是更改机器上的环境变量用户变量TEMP和TMP。路径：\温度℃，而不是默认的位置，包括你的用户名（与撇号）

The solution that has worked consistently for me is to change the Environment variables on the machine for the User Variables "TEMP" and "TMP". I repoint both of these variables to "c:\Temp" rather than the default location which includes your user name (with apostrophe) in the path.

通过每个Visual Studio中挣扎设置相关账户的具体路径（工程，模板等），这一直是我所需要作出解决问题的唯一变化之后。

After struggling through each Visual Studio setting related to account specific paths (Projects, Templates, etc.) this has been the only change I have needed to make to fix the problem.
