If you are struggling to set up C# support in Godot, give this video a watch. I will walk you through the installation and setup process. You will need some resources before getting started.

Godot .NET

.NET 6.0 - .NET version 6 is mandatory, do not use version 7!

Visual Studio Community - When installed visual studio, be sure to use the same options I did in the video. Using other settings may cause issues - don't install Xamarin or anything that isn't specifically required.
