There just isn't a product like Windows Forms that works anywhere but Windows. There are some very exotic solutions you could try that can get Windows Forms working on a Mac, but it usually involves a lot of tweaking for every single application. It's built on top of GDI, a Windows-only framework for developing applications. It's not SharpDevelop's fault, it's the "Windows" part of Windows Forms. That's the part that won't work on Mac OS. So SharpDevelop is like the great-great grandfather of current tools, that's how old it is. THAT project was discontinued after Microsoft bought it and now it's Visual Studio for Mac. THAT project is discontinued and became Xamarin Studio. That project is actually discontinued as far as I know and became MonoDevelop. I'm pretty sure it's cross-platform, but more on that later. It's even worse for a visual GUI designer like you're asking for. NET editors/IDEs isn't as exciting as it is on Windows.
