State: closed
Merged: Yes

Summary of the Pull Request

Fix the TabTests, and enable testing of types with XAML content. The TabTests were written many, many moons ago. they were intended to be our tests of XAML-like content within the Terminal app, so we could have unittests of Tabs, Panes, etc. Between their initial authoring and the day they were checked in, we had a bunch of build changes come in and break them irreperably.

We've gotten them fixed now with one weird trick doctors hate me. As long as there isn't an App.xbf in the test's output directory, then the tests will deploy just fine.

We also needed a bit of magic, cribbed straight from TAEF, to enable running test code synchronously on the UI thread. Hence, CppwinrtTailored.h.
