And best of all, both Server and WebAssembly has a lot in common, so it is possible to make that movment as needed. (I often prototype in server, as it's a lot easier to debug, too!)
If you are using Blazor Server, you don't have to even think about REST APIs. Depending on your app, that might be good or bad. But if you primarily target browsers on Desktop, you can tremendously improve productivity, because you can directly use C# POCO Models for UI and backend data services.
