Making SignalR Hub Strongly Typed
Explore how to create strongly typed SignalR hubs by defining client event interfaces in ASP.NET Core. Learn to replace string-based client calls with interface methods to avoid misspellings and enhance code safety, ensuring your hub communication is both reliable and strongly typed.
