UAP10 "Microsoft.NETCore.UniversalWindowsPlatform": "5.2.0" is too high?

The current project.json specified dependency as 5.2.0, yet the default template for UWP app is 5.1.0. Therefore the two can't work correctly together.

To repro:

1, use VS 2015 update 3 to create a new UWP app, it compiles alright.
2, add SSH.NET in by NuGet, then F6 will give us these errors:

If we change the UWP app json to 5.2.0, then all those will be gone. But this is probably prohibited for some people/project.

If there is no specific reason to require 5.2.0, can we change it to 5.1.0 so that it works out of box?

Empieza inspeccionando la dependencia de project.json para Microsoft.NETCore.UniversalWindowsPlatform y compara su versión con el requisito 5.1.0 de la plantilla UWP. Reproduce el problema en una aplicación UWP de VS 2015 Update 3 con SSH.NET instalado y, a continuación, verifica que cambiar la dependencia elimine el downgrade del paquete y los errores de compilación duplicados de Microsoft.Win32.Primitives.
