In this blog, you will learn how to collect Crash reports Using Visual Studio App Center in Xamarin forms.
Introduction
Xamarin.Forms code runs on multiple platforms - each of which has its own filesystem. This means that reading and writing files is most easily done using the native file APIs on each platform. Alternatively, embedded resources are a simpler solution to distribute data files with an app.
Visual Studio App Center
App Center have multiple services, that are most commonly used by mobile developers, where multiple services are acts as a single integrated product. With the use of single integrated product you can build, test, distribute, and monitor your mobile apps, and also implement push notifications.
Support Platforms

- iOS
- React Native
- UWP
- Xamarin
- macOS
- Cordova
Services
- Build
- Diagnostics (Formerly Crashes)
- Test
- Analytics

Crashes
Crashes will happens when a runtime exception occurs from an unexpected event, this crashes will terminates the app. These are the errors not handled by a try/catch block. When a crash occurs, App Center will records the details of the crash, then the state of the app and device are automatically generates a crash log based on the records. These logs contains valuable information about the crash and it will help you out to fix the crash.
