I thought I should get started writing XamForms and include Android as one of the target platforms but I'm having problems even creating a basic project.
I just created a Portable Blank App in Visual Studio. I then had to unload the UWP-project (I'm still stuck in Windows 7) but the Android project seems corrupt. Not even the reference to System is working (see screenie below - red parts are missing references/unknown identifiers, highlighted by Resharper).
What have I missed? I know almost nothing about Android development yet so please be gentle ... :-)
