Creating MvvmCross PCL to target Wp7.1 Xamarin.iOS, Xamarin.Android, .Net 4.5 and SL4 and higher

Question

After researching MVVMCross project, I am very keen to use it in a new mobile project and began setting out my project today. All was going fine until I tried to target the exact frameworks Stuart does in the "N=0 : A first MvvmCross Application" youtube video. I've no idea why this collection isn't allowed and I'm not as knowledgeable on PCLs and "profiles" as I could be.

Environment: I'm using VS2012, although VS2013 is installed also. WP7.1 is installed as is SL5 and Xamarin.iOS and Xamarin.Android. I've tried to repair both Xamarin installations because I thought the issue might have been that I installed WP7.1 after the Xamarin pair.

Also worth noting is that if I uncheck Windows Phone 7.5 and higher then it still won't work. I have to also set Silverlight 5 for the dialog to let me proceed. I'm not sure what more I can do do get this working so I'd appreciate any help I can get. All I want is to basically target the exact frameworks as are in that video mentioned above.

Answer 1

There are no Monotouch or Monodroid projects right now in Xamarin, so that link will not realy help you. They are called now Xamarin.iOS and Xamarin.Android. So what I've done that helped me, I've extended Profile 7, so it now supports WP7, iOS, Android and WinStore and it works great, no problems yet and I've already complete a couple of projects with it. So at that link - PCL Setup - you can find where all the profiles located and with that info try to extend Profile 7 as I suggested. So I've coppied the Windows Phone 7.xml from C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\v4.0\Profile\Profile131\SupportedFrameworks to C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\v4.5\Profile\Profile7\SupportedFrameworks

Answer 2

The video and PCL setup link are out of date now that Xamarin has released official support for PCLs. I'd recommend targeting the following platforms:

• Windows Phone 8
• Windows Store apps (Windows 8)
• .NET Framework 4.5
• Xamarin.iOS
• Xamarin.Android

And, optionally you can target Silverlight 5.
