Question

I am trying to create empty solution file for Visual studio 2010 but I am unable to do so?

We used to create empty solution file for vs2008 by
EnvDTE::_SolutionPtr ptrSoln(_T(“VisualStudio.Solution.9.0”)); but I am unable to find equivalent for VS2010.

I was able to find how to create project but not Solutions?

Answer 1

I found the answer. Answer lies in previous question mentioned by me – How can I create new blank solution in vs 2008 programmatically?

I forgot to add reference to EnvDTE, EnvDTE80. EnvDTE90 and EnvDTE100 assembly. Also name of solution class is Solution4 instead of Solution3. So code snippet which works is:

 string visualStudioProgID = "VisualStudio.Solution.10.0";
 Type solutionObjectType = System.Type.GetTypeFromProgID(visualStudioProgID, true);
 object obj = System.Activator.CreateInstance(solutionObjectType, true);
 Solution4 solutionObject = (Solution4)obj;
 solutionObject.Create("C:/", "Test");
 solutionObject.SaveAs(@"C:/Test.sln");
