Roslyn load project documents failing

问题:

In a Visual Studio Extension (VSIX) solution, I'm using Roslyn to load a specific project from my current solution:

Project myProject = 
    this.CurrentComponentModel.GetService<VisualStudioWorkspace>()
        .CurrentSolution.Projects
             .FirstOrDefault(p => p.Name == "MyProject")

The projct myProject is definitely loaded, but on inspection I see that:

myProject.HasDocuments == false
myProject.Documents is Empty

And yet, in Visual Studio I can see loads of documents.

If I close the solution and open the same solution but from another TFS branch, then the same code returns:

myProject.HasDocuments == true 
myProject.Documents is not Empty

Any ideas?

回答1:

I got this to work by:

1. Deleting the obj/debug folder
2. Cleaning
3. Transforming all T4 templates (this is ASP.NET MVC)
4. Restarting Visual Studio
5. Re-compiling

Simply re-compiling had no effect. Can't explain why, but the above formula worked for me.
