Built with .NET 5.0

This is a quick post to show how to implement a global exception handler in .NET 5.0.

These are the main pieces involved in the error handling process that we’ll cover in this tutorial:

• Global Error Handler Middleware - custom middleware that catches all exceptions and determines which HTTP response code to return based on the exception type.
• App Exception - a custom exception class that allows us to differentiate between handled exceptions thrown by application code and unhandled exceptions thrown by the .NET framework.
• Startup.cs - the .NET startup class that adds the global error handler middleware to the application request pipeline.
• Example Error Throwing Service - an example service that shows how to throw application exceptions that will be handled by the global error handler.

The below code snippets are taken from a .NET API tutorial I posted recently, for the full tutorial or to download and test the code locally see .NET 5.0 - Simple API for Authentication, Registration and User Management.
