Is it possible to open a solution (with projects targeting Xamarin.Ios, Android, mac and windows) made in Visual Studio under trail Business licence in Xamarin Studio?
You'll be able to open the Xamarin.iOS, Xamarin.Android and Mac projects, but the Windows projects won't load.
It is currently impossible to build a Windows Phone app using Xamarin Studio. You must use Visual Studio to build
WP projects. I'm not sure why this is the case. In another thread a xamarin rep stated that "We still have no plans to support building Windows Phone or Windows Store projects in Xamarin Studio"
This thread discusses it a bit more.
So, is it impossible to build application for Windows in Xamarin Studio?
All your shareable code should be in your Portable Class Library (PCL). You can use Xamarin Studio to build your Xamarin.iOS, Xamarin.Android apps, and use Visual Studio to build your Windows Phone apps. Or, use Visual Studio to build all three. No matter, both XS and VS should be able to build your PCLs. Visual Studio Community Edition is free, and you should be able to use that for your Windows Phone projects.
