I have been getting this for some time now, I cannot remember when it started sadly because I have had to rebuild my dev platform, so I am not sure if this has to do with the release of VS or not
When I try to prepare the package to upload to the play store I get the following error
MSB4094: "obj\Release\90\MyApp.Android.dll;obj\Release\90\MyApp.Android.dll" is an invalid value for the "OutputAssembly" parameter of the "Csc" task. Multiple items cannot be passed into a parameter of type "Microsoft.Build.Framework.ITaskItem". Done building project "MyApp.Android.csproj" -- FAILED. Build FAILED
If i unload the Android project then reload it, I can build the package, but only that time, when I go to make a newer release I have to once again unload then reload the project.
Has anyone else seen this? does anyone have any ideas?
