用test studio写代码时遇到的问题：
1. Exception thrown attempting to launch Internet Explorer. Please make sure Internet Explorer is properly installed and you are able to launch it.
还没找到解决方案...
Solution： make sure all projects build platform is AnyCPU.
2. Build时：
Can't build my service : Unable to copy file because it is being used by another process
Cause: The file is open in QTAgent32.exe
(QTAgent32.exe, PID 8116, Thread 8) ResolutionAppDomainHelper.Unload: An error occurred while attempting to unload the tests AppDomain. The AppDomain may still have foreground threads executing.
WorkAround: Restart vs 2010
3. Debug时：
Function evaluation disabled because a previous function evaluation timed out.
WorkAround: It is not really matter for running tests.
