I go through this scenario which is kind of annoying. I use Resharper 2.0(build 270)for Visual Studio 2003.
The scenario is :
1) I get latest from VSS. There are errors in files that someone has checked in.
2) I build. I obviously get errors in Task List window. So, I tell the person who is responsible to fix it.
3) Person fixes the issue. He then build on his machine and checks the changes into VSS.
4) I get the latest again and do a rebuild on solution. I still get the error and it will not clear until I close the ide and restart.
