Visual Studio抱怨未安装.net 4 [英] Visual Studio complains .net 4 not installed

问题描述

这让我发疯.

VS2010抱怨未安装.net 4，每次为每个加载的项目打开解决方案时，都会显示一个对话框您想转换为.net 4项目"，而在项目文件的目标平台".

我已经安装了.net 4定位补丁，但仍然可以继续.

This is driving me crazy.

VS2010 complains that .net 4 is not installed and gives you a dialog "do you want to convert to .net 4 project" every time you open a solution for every project loaded , and you don''t see .net 4 in the "Target Platform" of the project file.

I have installed the .net 4 targeting patch, but still it continues.

推荐答案

问题似乎与安装VS2010 SP1有关(至少在我看来). />
解决方法:

1)完全卸载VS2010.
1-1)如果已安装，也请卸载VS2012(在我的情况下为Express Web).
2)还要删除所有与VS相关的安装(SQLCE，ASP MVC等)
3)重新安装VS2010.

Problem seems to be with installing VS2010 SP1 (at least in my case).

Work around :

1) Uninstall VS2010 completely.
1-1) Uninstall VS2012 also if installed (Express Web in my case).
2) Remove All VS related installs also (SQLCE, ASP MVC, etc.)
3) Reinstall VS2010.
