Add Xamarin support

[Daiki-Kawanuma]

This SDK cannot be used on Xamarin projects due to "Microsoft.AspNet.WebApi.Client" package.

Package Microsoft.AspNet.WebApi.Client 5.2.3 is not compatible with netstandard1.6 (.NETStandard,Version=v1.6). Package Microsoft.AspNet.WebApi.Client 5.2.3 supports: - net45 (.NETFramework,Version=v4.5) - portable-net45+netcore45+wp8+wp81+wpa81

As described above, Microsoft.AspNet.WebApi.Client doesn't support MonoAndroid+MonoTouch+Xamarin.ios10.

Is it possible to support Xamarin?

@atilatosta Have you tested this?

Sorry for the late reply.

I tried to add this SDK package to Xamarin .NET Standard PCL project but it failed. The following is NuGet package install error.

@Daiki-Kawanuma hi! We believe that support is possible. We're working on it.

@mediumTaj We are doing some implementations and testing to try to make this possible

I would really love to see Xamarin supported. I'm running it on a Mac and have tried targeting my solution to every .NET framework version in the list, and no luck. The error I get makes it sound like the problem is the framework version I'm targeting, but the thread above seems to indicate deeper problems. Anyway, would love to have this if you can make it happen!
