MorseL is a light, .NET Core, replacement for SignalR. It's in...marginally active development.
This project exists because certain features (authentication) weren't baked into .NET Core SignalR. Additionally, the .NET Core libraries were too bleading edge to be used in an ongoing project. The intention is for MorseL to be swappable with SignalR when it stabilizes.
