In my Xamarin.IOS solution I have two projects, the first (an IOS project) references the second (which is a PCL 4.5 - profile78 project) . They both have had the Microsoft.Bcl.Build nugget package added.
However when I build I get this warning
Warning: All projects referencing FooSecondProject.csproj must install nuget package Microsoft.Bcl.Build. For more information, see http://go.microsoft.com/fwlink/?LinkID=317569. (FooFirstproject)
I note from this stack overflow question (in a different development environment, but same problem), the advice is to disable the warning.
I have not tried this yet but wanted to establish that this good advice. What is the cause of the problem, and should I be able to correct it ?
