Create a solution and add a project using “VisualS

问题:

I'm trying to create a VS2010 solution and add a project from a stand-alone app (not an add-in). I can create an instance of VS2010, but I'm not able to determine how to create a project properly...I can only find an example of how to create a project using the EnvDTE80 object, which later causes an exception because the project file is in an earlier format and needs to be upgraded. I have this:

EnvDTE80.DTE2 dte2;
object obj;
System.Type t;
t = System.Type.GetTypeFromProgID("VisualStudio.DTE.10.0", true);
obj = System.Activator.CreateInstance(t, true);
dte2 = (EnvDTE80.DTE2)obj;

What I'm looking for is the equivalent of something like "EnvDTE100.DTE2" but don't know how to get there.

Thanks

You do not have to go via DTE object. The treatment to the object solution4 it's different you should do this

Type latestSolution = Type.GetTypeFromProgID("VisualStudio.10.0", true);
EnvDTE100.Solution4 vsSolution = (EnvDTE100.Solution4)Activator.CreateInstance(latestSolution, true);

I think I'm doing something similar, I have a application that creates a solution and loads two projects from templates that I created in VS2010. You're right in that it seems everything still uses the EnvDTE80, even in VS2010, but then we use it to create a 2010 solution:

System.Type type = System.Type.GetTypeFromProgID("VisualStudio.DTE.10.0");
Object obj = System.Activator.CreateInstance(type, true);
EnvDTE80.DTE2 dte2 = (EnvDTE80.DTE2)obj;
EnvDTE100.Solution4 soln = (EnvDTE100.Solution4)dte2.Solution;

Then you can call methods on the soln object to create your project (in my case its AddFromTemplate).
