Description John Hardman 2017-01-27 12:54:49 UTC
Using Xamarin.Auth v1.3.2 in an x64 build for UWP results in the error:

There was a mismatch between the processor architecture of the project being built "AMD64" and the processor architecture of the reference "C:\Users\jh\.nuget\packages\Xamarin.Auth\1.3.2\lib\uap10.0\Xamarin.Auth.dll", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.	

Building as x86 does work, but x64 does not.

Similarly, using Xamarin.Auth v1.3.2 in an ARM build for UWP results in a similar message. It would seem that the NuGet package for Xamarin.Auth can not currently cope with 2 out of the 3 likely target platforms for UWP.

Please update nuget package. (And let me know if that fixes the issue, so I can close this bug).
