Early C# didn't have partial classes and had the generated code in the same file as all of the rest of your code, as well. They put it in regions that VS would automatically collapse for you, but it was still directly there. I think it was C# 2.0 that added partial class support and they started moving the designer generated code into separate files which was truly helpful. I don't think C# was ever as bad as MFC was with true magic generated code that you had better not change lest you inadvertently broke everything beyond repair (unless you really understood cryptic C++ error messages & preprocessor usage). MFC of the same era was not beginner friendly, even C# 1.0 was. I've never had the (dis)pleasure of doing java UI work, though, so I can't really comment on the state of things there.
