Mark Rendle Potentially in any audience I've been talking about WCF and gRPC for about a year now, and I ask the question "Who's using WCF?", and no hands go up. And then I ask "Who has legacy systems in their organization that are built with WCF?", and around 25% of the hands in the room go up. They've got these legacy systems. And so I want to talk a little bit about migration strategies to get from one thing to the other as well and to not get stuck with systems based on very old solutions.
