WP7 Integration for Testing and Building
WP7 is a great plattform for building apps but doing development more professional usages like unitt esting and continues integration is a pain.
I'll expect to integrate the unit testing framework into the VS IDE, automatically launching the emulator or phone to run the test. This should also be integrated in the TFS Build system.
Creating and running unit tests for phone should be optimized but the biggest problem is that the phone emulator will not run in a build server which has been set up as a virtual machine.
