Yeah, Service Fabric is super awesome! I'm refactoring out company's infrastructure to run on it currently - the older stuff runs on MVC 5 on Azure Cloud Service.
I'm refactoring it to ASP.NET Core on Service Fabric. Getting about 50x better real-world performance. Yes, that much. It's insane. Currently on Windows as Service Fabric on Linux is in preview (not comfortable using it in production), but I imagine I'll move it over once that's stable ️
A great time to be a .NET developer! Makes me happy I stuck with it.
