I submit a test Windows Phone Silverlight Project 8.1 and get this error when submit
The package identity associated with this update doesn't match the uploaded appx: "2e740376-677c-4df8-b1af-95b72863f017"
Windows Phone 8.0 project dont meet that error. Any suggestion? Thanks

You can find these values in the Windows Store Dasboard in the App identity section:
You then need to copy and paste these values inside your Package.appxmanifest file. Note you have to open this file using text editor. These values are not editable using the UI editor:
