Publishing a Mango Update to an Existing App

Assuming you’ve published Windows Phone applications to the Marketplace, you’re probably wondering how things will work if / when you want to update those apps to Mango. There’s a good post on the Windows Phone Developer Blog that details exactly what will happen:

What happens when I publish a Windows Phone ‘Mango’ application update?

Key points to note:

  • “Once you have released the WP ‘Mango’ version of your application, you will no longer be able to modify the previously released WP 7.0 version of your app” (though we’re investigating ways to mitigate this)
  • “The application metadata and screenshots for Windows Phone Marketplace submitted with the WP ‘Mango’ version of your application will be shared across both the WP 7.0 and WP ‘Mango’ versions of the application”
    • This means you need to be very clear in detailing any version specific features
    • The same applies for screenshots that are representative of only one version
