In this course, we learn how to use the open source .NET Polly library to automatically retry operations rather than failing on the first exception.
By the end of this course you’ll know how to effectively and easily handle temporary transient errors in applications and provide great user experiences by creating more robust and resilient applications that don’t interrupt the user unnecessarily. Transient errors such as temporary network connectivity problems or fleeting database problems can cause more users to report errors and more error log entries that can waste valuable developer time. In this course, we learn how to use the open source .NET Polly library to automatically retry operations rather than failing on the first exception.
