When I want to clean and build my Xamarin.Forms project with Xamarin studio i get the following error:
Error: MyProject.iOS.csproj: Object reference not set to an instance of an object (Myproject.iOS)
I get the same error for the android version.
The error appears since an update of xamarin studio has been installed.
Furthermore xamarin studio does not know Xamarin.Forms anymore. I uninstalled and installed the xamarin.forms package.
I guess it is some settings issue but do not have an idea what the problem could be.
So my question is: what could be the problem here?
