"Object reference not set to an instance of an object" when creating NEW Windows Phone project [WP8 SDK, VS2012 Pro] RRS feed

  • Question

  • I have Windows 8 x64 (not pro), VS2012 Pro Update 3, WP8 SDK and cannot create any new Windows Phone project.

    I tried the following to no avail (in admin as well as non-admin accounts)
    (numerous times, in different permutations)
    1. Uninstall all Silverlight SDKs and components
    2. Uninstall WP8 SDK
    3. Uninstall all VS2012 components
    4. Reboot
    5. Clean registry
    6. a. Reinstall VS2012 Pro \ Update VS2012 \ WP8 SDK (with reboots each time) Did not work
    6. b. Reinstall VS2012 Pro \ WP8 SDK \ Update VS2012 (with reboots each time) Did not work.
    7. Started devenv /ResetSettings (did not help)
    8. Started devenv /ResetSkipPkgs (did not help)
    9. Updated Silverlight (before\after all installs --different permutations)

    Nothing helped.  Exhausted all possible "solutions" listed on various sites.
    I can open and run all other project types *EXCEPT* any of Windows Phone template projects.  It does not even create a solution.

    Please help.

  • OK. Finally able to create a *new* Windows Phone App project!!

    Solution: **UNINSTALLED** NuGet (as updates to it did not work)
