Although most of the attention is on .NET Core, development continues on the original .NET Framework. Microsoft has recently released a preview of .NET Framework 4.7.2 with updates to ASP.NET, ADO.NET, WCF, WPF, and even Windows Forms. You can see the complete release notes on GitHub. 

Channels are a construct that simplifies concurrent execution and pipelining of data and is often touted as one of the main draws of Go. But did you know that .NET also has built-in support for channels?
