CoreWCF is a port of WCF to .NET Core. It’s a community project but will be supported by Microsoft and is intended to help migrate .NET framework apps to more recent versions like .NET 5/6.
Note… Microsoft still recommends using something like gRPC or REST APIs for greenfield projects.
Have you a use case for this or have you already dropped all WCF services and moved to other service approaches available in .NET Core?
I asked this question a while ago on my LinkedIn page and although the number of votes was relatively low at 104 I was still kind of surprised that nearly 40% of devs thought they might have a use case for it.
