"Create Unit Tests..." does not display any types (empty dialog). Also, clicking on the "Settings..." button seems to close the dialog. This only seems to happen when the solution contains an InstallShield LE project. Removing the InstallShield
LE project from the solution resolves the issue.
This seems real similar to an issue VS2008 SP1 had that was corrected with hotfix KB962866. (I did not have the issue with VS2008.)
Same problem, can't find any solution (besides temporarily removing InstallShield LE Project)...One more consequence of the usage of InstallShield. Is there a VS2010 hotfix for this problem? Can't find anything...
