I'm on the way to update my WP-app in the windows app store.
In the meantime (after my first submit of the WP 8.0 app):
Now, I wanted to update my app in the new Windows Dev Center...
Thereby I had / have some problems (wasted about 5 hours until now)...
Therefore I write this message (to help other developers save time)...
It seems as - with the WP 8.1 migration a new file named PackageAppxmanifest take place (I don't remember to have seen it before).
This file contains some important data, that have to be correct and seems to be false per default.
Further, it seems as there are some new images, that **have to ** be replaced with your own files.
By my tries to update the package, I received strange error-messages and then searched for the values in the file-explorer in the WP project...
=> So I have found the PackageAppxmanifest-file...
I then have edited the PackageAppxmanifest-file with an editor and changed the "false" values (from error-message in the Dev Center) thru the "expected" values in the error-messages (by copy-paste from Dev Center).
Then I was able to submit the package...
After about 10 minutes I had a "certification-error"
Error-Messages and file-names:
Image file StoreLogo.png is a default image.
=> 120 x 120 Pixel, 32 Bit”
Image file Logo.png is a default image.
=> 106 x 106 Pixel , 32 Bit
Image file SquareTile71x71.png is a default image.
=> 170 x 170 Pixel , 32 Bit
Image file SquareTile150x150.png is a default image.
=> 360 x 360 Pixel, 32 Bit
The (empty) file-templates are stored under the **\Assets** subfolder of the WP project.
This files are "empty" per default
=>I replace them tomorrow and hope. the package then will be accepted
By my searches for the name of one if the new images, I found this very useful blog that explains the problems:
I wonder (one more time!) that I don't have found such information's here in the XF forum
But maybe, I don't have searched enough
However... hope this helps someone and my app will be accepted, after I have changed the new images
