问题
I recently upgraded my WP8 Silverlight Application to 8.1 Silverlight. But now, ehwn building I always get this error message
AppManifest Validation failed. Invalid AppPlatformVersion in WMAppmanifest.xml Bedtime Music
What went wrong and how can I fix this.
Thanks

Nah, I found out by myself: In the WMAppmanifest file there is this line:
<Deployment xmlns="http://schemas.microsoft.com/windowsphone/2012/deployment" AppPlatformVersion="8.0">
To deal with the resulting error that occurs when just setting 8.0 to 8.1 I also needed to change the year from 2012 to 2014
<Deployment xmlns="http://schemas.microsoft.com/windowsphone/2014/deployment" AppPlatformVersion="8.1">
Also somewehere else in the file.
