I am trying to create a Portable Class Library that will be used in an Android project and make use of System.Threading.Tasks.Task and System.Collections.Generic.HashSet. Both classes are included in .NET portable profile and my code compiles. However when I add Mono for Android as one of the target frameworks for my PCL the classes become unavailable.
Given that you have implemented these what is the right way to bring these into a PCL that can be referenced from an Android application? It might be related to the earlier thread for HttpClient and I am looking for some strategic guidance that does not involve rebuilding mono sources as PCLs - is it possible?
Thanks for your help
