Hello,

i want to manipulate a C++ VCProject with C#-Code. Especially, i want to add a project reference. Every attempt to add a project reference with AddProjectReference() leads to an exception. (System.InvalidCastException because the desired data is in a zombie state)

Has anybody an idea what i do wrong?

Thanks in advance.

VCProjectEngine vcProjectEngine = new VCProjectEngineObjectClass();
VCProject project1 = (VCProject)vcProjectEngine.LoadProject(@"C:\test1\test1.vcproj");
VCProject project2 = (VCProject)vcProjectEngine.LoadProject(@"C:\test1\test2.vcproj");


project1.AddProjectReference(project2);
