Create a blank solution using the envdte

Question

Hello, I have a list of project files (all full path and name) and I want to create a new solution and then add all these projects to this solution. This is what I tried. EnvDTE.Solution mysol = new EnvDTE.SolutionClass(); mySol.Create(@"C:\temp", "dummySolution.sln"); foreach(string myProj in _Projects) //_Projects is a list of project files) { mySol.AddFromFile(myProj, true); } mySol.Save(@"C:\temp\dummySolution.sln") The application keeps on busy for a while and then I get a System.Runtime.InteropServices.COMEException Additional information: Server execution failed. Can anybody tell me what is wrong or what I should do instaid. Thanks in advance, Johan.
