Answer 1

The problem is solved now.

Here is what I did, as suggested in the forum:

1. Uninstall WP8 SDK
2. Uninstall all instances of Silverlight SDK and Rutime.
3. Re-install WP8 SDK.

The exact order in which I fixed the VS designer problem:

1. Uninstalled all WP7 SDK:
2. Restarted computer (The designer still failed after this step)
3. Uninstalled WP8 SDK (Maybe it is enough to choose repair here, but I selected to uninstall the SDK)
4. Restarted computer
5. Installed the WP8 SDK

The designer works perfectly now :)
