I switched from running Visual Studio using Parallels on my Mac to using Xamarin Studio directly on my Mac. Had too many issues getting my phone detected properly. So far everything is great for the mobile applications using XS directly on my Mac.
I see that Xamarin Studio has project templates for MVC web applications. The MVC project works from my testing, but has anyone had any success getting Web API to work? It seems as though mono doesn't support the latest version of Web API that is available through the nuget repository. There doesn't seem to be a way to pull older versions. From my research it seems as though one needs the ASP.NET MVC 4 nuget package. It would be great if I could bypass Windows and VS all together for mobile development.
