Hi,
 I can't seem to get the following macro to work:

   Sub BuildProject()
       DTE.Solution.Create("C:\\", "MyTestSolution")
       DTE.Solution.SaveAs("C:\\MyTestSolution")
       DTE.Solution.AddFromFile("C:\\test.vcproj")
       DTE.Solution.AddFromFile("C:\\anothertest.vcproj")

       If (DTE.Solution.Projects.Count > 1) Then
           Dim myproj As EnvDTE.Project
           myproj = DTE.Solution.Projects.Item(1)
           If Not (myproj Is Nothing) Then
               DTE.Solution.SolutionBuild.ActiveConfiguration.Activate()
               
DTE.Solution.SolutionBuild.BuildProject(DTE.Solution.SolutionBuild.ActiveConfiguration.Name, myproj.Name, False)
           End If
       End If
   End Sub

 I can confirm that the ActiveConfiguration name in this case does exist so
it shouldn't fail.
