I've recently came to C# to Java to see if I could get any success creating an application in this way, by creating a few window tests.
I want to do this in pure code (like I did in Java), and want a library similar to Java's
And, I found something that looks suitable,
System.Windows.Form, but, as far as I've read, and as the name (kinda) implies, it's windows exclusive.
Is there any cross-platform library that accomplishes the same things, with a similar formatting (to that or the one in Java)?
