Microsoft Windows Phone 10 .net Client SDK

The NuGet package was built for .NET 4.5 and may not be compatible with your framework version due to its dependency to unirest library.
What you can easily do is this:

  • pull latest source code from GitHub,
  • open SDK solution in visual studio,
  • select target .NET framework at your choice,
  • build.
    This way you get assembly fully compatible with your ecosystem.
