(only the most recent commit here is relevant)

Briefly tried out wasm-experimental workflow to see if we could get multithreading for free.

I got the workload installed, and code written to try and spawn a new thread, but then met with:\

Uncaught (in promise) Error: Failed to start platform. Reason: ReferenceError: SharedArrayBuffer is not defined

apparently this might be resolvable with some headers:

("Cross-Origin-Embedder-Policy", "require-corp")
("Cross-Origin-Opener-Policy", "same-origin")

but I'm not sure which requests/responses need those - maybe all, in which case serving the static assets by a different host won't work...

This sort of feels like a dead-end due to security+convenience constraints.

if I load the static assets from the same host, I hit a different issue as Blazor is loading.

Seems related to this:
dotnet/runtime#68162 (comment)

Seems like a known thing, and we should probably just wait for improved support (maybe in .net 8)
