The library now targets .NETStandard 1.1 (.NET Core) and can be used on any platform supporting .NETStandard 1.1.
Due to .NETStandard support, the library is not separated into two parts (UWP/NetFx) anymore. One library for all the target platforms.
Breaking change: The whole library is now based on System.Net.Http.HttpClient. Therefore, there are some changes in the API (e.g. method signatures).
Upload/download with progress is generally supported, even on projects targeting .NET Framework (formerly the NetFx part of the library).
The xml:lang attribute is now supported for prop elements.
