For me, I just ran into this trying to build a project pulled from TFS on a new VS 2015 Update 2 install. Not sure what exactly fixed it but this is what I did:

1. Download Android API 23 and 22 SDK from the SDK Manager and also updated all other items in SDK Manager (had to close and open it twice to get it totally up-to-date).

2. Nuget Restore packages (this did not fully fix it).

3. Followed these instructions where you go into all .csproj file in the solution and remove all mentions of nuget. Also do this in the solution file, but mine had nothing.

4. Use Package Console and run Update-Package -Reinstall (of if you know these package were building just fine before, I ran ``Update-Package -Reinstall -IgnoreDependencies`) and choose the project if you want.

5. Still had a couple errors from the Android Resource Designer file so did a build and everything was right in the world again.

For me it was a Mono.Android.dll version issue. I removed the reference, and added a reference to the right version.
