.NET 6 - The ArgumentNullException helper class

.NET 6 introduces a new helper class that uses the new [CallerArgumentExpression] attribute and the [DoesNotReturn] attribute; the ArgumentNullException helper class.

This class gives you an easy-to-use helper class that throws an ArgumentNullException for null values.

Thanks to the [CallerArgumentExpression] attribute this helper method gives you better error messages as it can capture the expressions passed to a method.

This is the implementation of this helper class:

Before C# 10, you probably would have used the nameof keyword and implemented this helper class like this:

That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cleaner switch expressions with pattern matching in C#

Ever find yourself mapping multiple string values to the same result? Being a C# developer for a long time, I sometimes forget that the C# has evolved so I still dare to chain case labels or reach for a dictionary. Of course with pattern matching this is no longer necessary. With pattern matching, you can express things inline, declaratively, and with zero repetition. A small example I was working on a small script that should invoke different actions depending on the environment. As our developers were using different variations for the same environment e.g.  "tst" alongside "test" , "prd" alongside "prod" .  We asked to streamline this a long time ago, but as these things happen, we still see variations in the wild. This brought me to the following code that is a perfect example for pattern matching: The or keyword here is a logical pattern combinator , not a boolean operator. It matches if either of the specified pattern...
