Real multithreading in Blazor WebAssembly

[BlenderMender]

Is your feature request related to a problem? Please describe.

I have load of CPU intensive requests connected to vial for the application data from sensors, and I would like to have a real multithreading for multiple sources which streams large amount of data nonstop.

Describe the solution you'd like

Multithreading which is available already in WEBASM to be exposed to Blazor Client side.

Thanks for contacting us, @BlenderMender.
WASM 1.0 spec doesn't include real multithreading, and this is the spec we currently target. We expect improvements in this area in the future.

Wonder if the actual issue is letting JS be multithreaded and some peoples fear that this will cause some disturbance because threadings.
If this is the case I have the follow suggestion:

• Let the JS use 1 thread locked only for it - emulating the current state of the things, and the rest threads be free for background work of the C# application.

I would dive deep into blazor (without any return) if there would be support for multithreading for client side. Make it happen!

I've created a small library called BlazorWorker which creates a new dotnet process using web workers. It's very similar to multithreading, main difference being no shared memory, only message passing @BlenderMender @Marcin-Perz I would appreciate your feedback on the API, to see if it's a path worth pursuing in the meantime.
