Programmatically Reloading Project/Solution

EnvDTE has a ProjectsEvents class that has three methods: ItemAdded, ItemRemoved, and ItemRenamed. You could poll for these events, and after your code makes any changes, you can have it reload the project.

You can use EnvDTE.Solution.Close and then EnvDTE.Solution.Open to close and then reopen the solution respectively.
