We do have Windows tests (run exclusively on the Peak environment for Round 9), but most of the ASP.NET tests are not starting and passing validation correctly as-is. We'd like to get these fixed up along with all of the other tests that are not passing validation and running correctly. As you might expect, we have a never-ending game of whack-a-mole with so many frameworks in play, so we lean heavily on the community to assist. We'd love to get pull requests to help validate the existing .NET tests.
