VS2013 Xamarin's incompatible plugin when installing VS2015...
As a good .NET developer, yesterday I installed the new Visual Studio 2015 IDE to discover all its new features... VS2015 installed ! I was previously developping mobile apps with Xamarin on VS2013. So as I am impatient I installed VS2015 without thinking of all the modifications it can bring to my environment... And bingo ! When I started back VS2013 to edit my Xamarin's projects, I had a bad surprise: iOS & Android projects no more compatible... But, fortunately, I find a really quick solution to restore Xamarin compatibility with VS2013. In fact in the windows programs / functionnalities menu, I changed the Xamarin app components configuration like above: Xamarin, change installation Xamarin for Visual Studio 2013 is disabled ! Re-enable it and it s all good :) And go you can continue to develop Xamarin projects with VS2013 !
