Add an existing project to solution folder using PowerShell

Question

I'm working on a PowerShell script to dynamically create and add a Visual Studio project with its folders and assets to a solution. I'm using Visual Studio DTE.

My directory structure on the file system is the following:

C:\Dir1\Dir2\Stuff
|
+--Stuff                  <-- folder
|  |
|  `Stuff.csproj          <-- existing project, included in sln
|
+--Subfolder              <-- Subfolder in which I want to include my new csproj
|  +--Project1            <-- folder
|  |  |
|  |  `Project1.csproj    <-- existing project, included in sln
|  |
|  +--Project2            <-- folder
|  |  |
|  |  `Project2.csproj    <-- existing project, included in sln
|  |
|  `--Project3            <-- this, subs below and csproj are created from my script
|     |
|     `Project3.csproj
|
 `Stuff.sln

My script creates Subfolder\Project3\Project3.csproj correctly, and I can add it to the solution without any problems, using DTE.

I want, however, to add Project3 in the solution folder 'Subfolder', so it looks like this (dummy image, red arrow shows where I want to have Project3):

How can I accomplish this using Powershell (and optionally EnvDTE)? Any example code would be appreciated. Thanks!

The SolutionFolder interface has an "add from file" method:

http://msdn.microsoft.com/en-us/library/envdte80.solutionfolder.addfromfile

Project AddFromFile(
    string FileName
)

So you just need to get a handle to the solution folder. I don't know if you are adding the solution folder through the DTE or it already exists.

If you add it with Solution2.AddSolutionFolder

http://msdn.microsoft.com/en-us/library/envdte80.solution2.addsolutionfolder%28v=vs.110%29.aspx

Project AddSolutionFolder(
    string Name
)

It returns a reference to the solution folder and you can just call the above method. If it already exists, I think you'll have to use Solution2.FindProjectItem.

http://msdn.microsoft.com/en-us/library/2zszfd26%28v=vs.110%29.aspx

Something like the following should work. I don't have a way to try it out at the minute so tweaking might be necessary.

Solution solution = System.Activator.CreateInstance(Type.GetTypeFromProgID("VisualStudio.Solution")) as EnvDTE.Solution;
Solution2 sol2 = solution as Solution2;
sol2.Create(solutionPath, solutionName);

Project folder = sol2.AddSolutionFolder("Subfolder");

folder.AddFromFile(pathToProject);
