Introducing C# 9: Extending Partial Methods

C# 8 (and above) has some restrictions regarding partial methods. For example : - Partial methods must have a void return type - Partial methods can’t have out parameters - Partial methods can’t have any accessibility keyword (public, private, protected etc….) C# 9 aims to remove these restrictions. If you want to learn more about the motivation behind this, you can find a good description on the Github page here: https://github.com/jaredpar/csharplang/blob/partial/proposals/extending-partial-methods.md
