I'm getting the the following error when trying to open a Xamarin.iOS project in Visual Studio 2012/2013: "Some of the properties associated with the solution could not be read.[file-path-to-.csproj] : error : The attribute "Include" in element is unrecognized. [file-path-to-.csproj]"; however, it opens just fine in Xamarin Studio for OS X.
This is for a project file that was created with Xamarin Studio for OS X. A Xamarin.iOS project created in Visual Studio 2012/2013 opens just fine.
Thanks for any help.
