If you’re writing a Metro style app for Windows 8, here’s how you can share it with another developer. Note that both the source and destination machines need a valid development license. Verify this with the PowerShell cmdlet
In Visual Studio, choose Create App Package under the Store menu:
Select Create a package to use locally only:
Make note of where the package will be saved, and then click Create:
Navigate to the package location, right-click on your package’s folder, and select Send to –> Compressed (zipped) folder. You don’t need the .APPXUPLOAD file.
Mail the zipfile to another developer, or otherwise transfer it to a second machine. Remember that the destination machine must have a valid developer’s license. Extract the zipfile, and then run
Add-AppxDevPackage.bat as Administrator. The app will then show up in the target machine’s Start Screen.
