一个异常的解决

QueryService for '{74946829-37A0-11D2-A273-00C04F8EF4FF}' failed.

Once I try to create or open any project I get the message:

Project '(project name)' could not be opened because the Microsoft Visual C# 2008 compiler could not be created. QueryService for '{74946829-37A0-11D2-A273-00C04F8EF4FF}' failed.

I've just solved the same problem by
1. uninstalling everything related to vs 2005, 2008, .net framework 2.0, 3.0, 3.5
2. installing vs 2008
3. running devenv /resetsettings
4. running devenv /resetskippkgs

And, by the way, I tried steps 3 and 4 before reinstall - they didnt' help.

以上的内容来自网络，但是我只做了3，4步就ok了。
