Using the Diagnostics UI


Visual Studio App Center is scheduled for retirement on March 31, 2025. While you can continue to use Visual Studio App Center until it is fully retired, there are several recommended alternatives that you may consider migrating to.

App Center’s Diagnostics service is designed for you to easily monitor your apps' health and get the information you need to fix issues.

  1. Login to the App Center Portal
  2. Select an application
  3. In the navigation area on the left, select Diagnostics

App Center displays the crashes and errors in one view under the Issues tab. You can filter these issues by crashes or errors by clicking the respective tabs.

For all apps, you can filter the diagnostics data by app version, build number, time range and status. Click on a group to find more information including a list of specific reports, devices and OS versions affected.
