Handling errors

The exception handling process in a .NET-based Function App is similar to any other .NET application. Best practices for handling exceptions in .NET can be found at the following two links:

• Code project: https://www.codeproject.com/Articles/9538/Exception-Handling-Best-Practices-inNET

We will not elaborate on best practices further in this book.

Let us, instead, outline the error handling in Functions Core tools local environment for two cases--handled and unhandled exceptions.

To demonstrate exception handling, let us create another timer-triggered function called ErrorFunction. To do so, follow the same steps as in the previous section on creating the test function, and move on to the following steps:

1. When the function is created, open the ErrorFunction.cs file, and paste the following code. As you can see, the following code generates an unhandled exception:

        using System;
        using Microsoft...
