I have started experimenting with the Nuclex GUI port. While it looks promising, I tried to create a custom GUI element with a custom renderer, derived from IFlatControlRenderer. The problem now is that I can't register it anywhere as a renderer. While looking at the code, I realized that Nuclex GUI can only use renderers in it's own binary.
Do you know if there is any way to have a custom renderer, without compiling Nuclex GUI? I use it from nugget so I do not compile it for now.
