Standard.Licensing

Easy-to-use licensing library for .NET Framework, Mono, .NET Core, and Xamarin products.

This is project is derived from Portable.Licensing library. The purpose of this fork is to add support for more .NET platforms, especially .NET Standard and .NET Core.

There is also a plan to decouple from Bouncy Castle library and use System.Security.Cryptography.Cng for modern .NET platforms.
