C# 8–Null-coalescing

Although C# 8 is released for a while, I’m still discovering new features.

When I want to conditionally assign a value to a variable whether it is null or not, I typically used either the conditional ternary operator:

	List<string> productNames=null;
	productNames=productNames==null?new List<string>(): productNames;

or a coalesce expression:

	List<string> productNames = null;
	productNames = productNames ?? new List<string>();

With C# 8, you can even write this shorter with the null coalescing operator:

	List<string> productNames = null;
	productNames ??= new List<string>();
