Monogame platform-independent interfaces?

I divided my project in a bunch of assemblies. When I tried use them as I shared projects there was a lot of pain in Jet Brains Rider (which is more convinient for me than a Visual Studio). So I am building facade around Monogame to refer only interfaces in my assemblies wich will be platform-independent. So why doesn’t monogame have a separate nuggent with interfaces, vectors, colors and so forth? Or maybe it does but I don’t know. Is there any work in this direction? Gracias!
