I first want to apologize for the delayed response - since the issue is posted in our forums, its response time is not guaranteed. I would therefore recommend that you post such cases through the ticketing system as this way we can handle them in a shorter and guaranteed response time. In any case, I do hope that you were able to resolve the issue. Judging from the ticket submission date I believe you hit a temporary issue we were having with our infrastructure during the update.
If you haven't done so already, would you please try installing the latest version of AppBuilder
on your machine again. This tutorial
describes how to download the extension from the Telerik Platform portal but you can also use the Visual Studio extension manager. The installation should now work as expected and the latest version should resolve the WP8PackageIdentityName
error as well.
If the installation succeeds but you still see an error with the WP8PackageIdentityName
property do let us know so we can further investigate the case. Basically, the error comes from a failed validation of the Package Identity Name
field value which you can manually update from the Windows Phone project properties
of your AppBuilder
Let me know if the new installation helps and if you have any questions I can answer for you.
