C# is so painful to find what I want. Last time I want to write a quick GUI, I gave up and go to youtube because they are simply easier.
Still supported in .net 8. Windows only though.
Beyond that, I have not bothered.
GUI might be special a case because there are so many flavors of it, and half of them are abandoned dead-ends.
dotnet new --install Avalonia.Templates
dotnet new avalonia.app
dotnet run
Will work on any platform.
