I would suggest looking into supporting Blazor client-side programming with ServiceStack, at least a C# client that works with the ServiceStack cli (https://docs.servicestack.net/csharp-client).
From v6 ServiceStack now has first-class for Blazor WASM, checkout the release notes:
The official docs for Blazor WASM is now at:
Client Template for Blazor WebAssembly client-side.

Starter template with Blazor authentication/authorization integrated into SS. Also a working SS Httpclient + SSE example.

I'm also hoping for Blazor Server support. This could be just a SS ComponentBase with templates for integration with SS Auth.
