Embed WebAssembly components inside Blazor Hybrid #48568

Is there an existing issue for this?

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

Some Blazor components work only with WebAssembly Blazor, for example SkiaSharp: https://www.nuget.org/packages/SkiaSharp.Views.Blazor

It would be great to be able to wrap them in a simple component, mark it as RenderMode=WebAssembly, and then expose a property that would be debounced/throttled in WA, so that we can pass some values both ways

Blazor Hybrid is very similar to Blazor Server, just instead of web sockets, there communication happens by passing around base64 data. Performance for that wasn't the focus so far (for example https://github.com/dotnet/maui/issues/12767 is still opened and in backlog).

That means that I cannot write the whole app in Blazor in an easy way - I can hack some custom html component and put that in wwwroot directory (I think). That adds way too much complexity.

Alternative is to high perf parts in the hosting tech, like MAUI, but that makes matching styles super hard, and it requires some hacks to display native control on top of webview.

Describe the solution you'd like

I would like to be able to use RenderMode.WebAssembly in Blazor Hybrid app, with all the out-of-box goodies, like parameter binding

Additional context

Part of my WPF app is doing image editing, similar to Ms Paint - with SkiaSharp.Blazor I expected to be able to just replace the bitmap drawing part with Skia and be good to go, but doing that in the native process means that the image has to be transported as base64 to the WebView - with image being bigger than 300x300px this becomes super slow.

I can do it in JS and just refernce it in Blazor, but being able to do it in Blazor directly would obviosly be so much better. And it is possible today, but only in WebAssembly mode
