Description

The EnvDTE.DTE.ActiveSolutionProjects property causes a COMException in Visual Studio 11 Beta when the following two conditions are met:

1) The Solution Explorer toolwindow has not been shown.
2) No solution is loaded

It didn't happen in Visual Studio 2005/2008.

Visual Studio 2010 has its own bug but somewhat different: only condition #1 is required. I reported it separately:

Agreed that ideally we would return an empty array instead of throwing an exception. However since there is a workaround of calling DTE.Solution.IsOpen before calling DTE.ActiveSolutionProjects, this bug falls below the bar with respect to the other remaining work items we have for VS11. Thus we will not be able to fix this in VS11.

Hello,

While I agree that add-ins should check DTE.Solution.IsOpen before calling DTE.ActiveSolutionProjects (or maybe not, the check could be done in the DTE.ActiveSolutionProjects property and save all add-ins in the world that check), this is a bug because it breaks backwards compatibility: in VS 2008 it didn't happen, and therefore it breaks add-ins relying on the behavior of NOT checking DTE.Solution.IsOpen before calling DTE.ActiveSolutionProjects and instead assuming that DTE.ActiveSolutionProjects would return an empty array if there is no solution loaded.

Thanks for your feedback. So from your description, it seems that when a solution is loaded and the Solution Explorer is not open, DTE.ActiveSolutionProjects property still returns a valid value. However, when in addition to the Solution Explorer being closed and there being no solution loaded, an exception happens. Is this correct? If so, could you elaborate on why you need to use this DTE API when there are no solutions active?
