Since I’m working in a OS X environment nowadays, I don’t know anything about visual studio community (or whatever it’s called). However, when I’m on windows, I use an old copy of visual studio called express 2013. It was(and still is) completly free and it works like a charm with monogame.
You should be able to use the free Visual Studio Community Edition. It’s roughly equal to Visual Studio Professional with regards to features, and I’ve personally had no issues using it with MonoGame and similar frameworks.
Where did you see or hear that Community Edition didn’t support MonoGame? It works wonderfully with MonoGame to produce Windows desktop applications (DirectX, OpenGL), Windows Store apps, Windows Phone 8 apps, and with the appropriate Xamarin license, Android and iOS apps as well.
Doing fine on VS2013 Community edition here! Although I’ve yet to test running anything iOS/Android from here - I normally do all my code-up in VS then share create projects in Xamarin Studio for iOS and Android and just share the code files.
And it’s your only option if you want to stay on Windows and develop an iOS app (via a Mac as the build and debug agent) as XS on Windows does not support iOS in this way.
