I've tried to create a new monogame windows phone 8 project, when I tried to run it I got this error:
Error 1 The "GenerateWinPRTManifest" task failed unexpectedly.
System.ArgumentException: An item with the same key has already been added.

I got this error today.
I had referenced DLLs which had been compiled for a different architecture (ARM instead of x86).
So built them again, removed their reference and referenced them again.
Hope this helps

Just one update - I've got same error today too at my WP8.0 project. I have two projects using Lumia.Imaging SDK added by NuGet - different time, so different lib version. But just remove reference in VS2013 on both project and ensure to to target same .dll wasn't enought for me. I had to edit *.csproj file in text editor of my older project and remove all reference on that library there too. And after it just add .dll by hand works fine for me.
