I do wonder about the scalability of the Blazor Server mode which requires live and "sticky" SignalR connections.
* Unclear state management story in Blazor WASM. There is a flux lib for Blazor but.. Ugh, I'm spoiled by MobX. Another project, Cortex.Net, inspired by MobX and uses Fody to make seamless fine-grain change subscriptions looked promising but the project did not gain traction :(
* Unclear runtime extensibility: How can I "plug-in" Blazor components that were not present at build time? That's a ASP.NET challenge in general TBH.
I REALLY want to want to use it though. That sweet, sweet isomorphism.
- Runtime extensibility: you can do whatever you want in C# so you do you. In addition there is also DynamicComponent now, which is what I believe you are looking for.
