I added this sample project to my git repository and setup a xamarin android build on VSO. I'm using the hosted build agent and getting the following error...

I'm getting this same error and it is driving me nuts trying to find a solution. The app builds just fine in debug and release mode on my local machine, and builds in debug mode on VSTS, but building in release mode causes this error.

WOOT! I just solved this problem!
On the Droid project properties page in the solution in VS2015, the "Compile using Android Version" was set to Android 7. I changed the "Compile using" value to Android 6. I did not change the minimum android to target nor the target android version (which are set to 4.0.3 and 6.0, respectively).
Once I checked in this change to the MyApp.Droid.csproj file, the CI build kicked in and for the first time it completed without the linker error!
I also confirmed that after this change, the debug and release versions of the app still build on my local machine without issue!
