My project is a standalone Blazor Wasm application. According to the AI, the routing in this kind of app is different from the server-side router, hence there is no way to extend the constraint map. (I am using route constraints without issues in WebAPI apps.) After everything is registered similar to the server-side approach, the DefaultInlineConstraintResolver complains.

I am a little bit confused, as I got a comment here that it should work:

I haven't found any authoritative documentation that makes an explicit statement about this being or not being supported. Does this necessitate different setup steps as on the server side, or it is completely unsupported?
