You read my mind, Dan. I was just about to open an issue

[guardrex]

This is currently a section of the Blazor WASM host and deploy doc at ...

https://docs.microsoft.com/en-us/aspnet/core/blazor/host-and-deploy/webassembly?view=aspnetcore-6.0#native-dependencies-support

@danroth27 ... I'm 👂 if you prefer a dedicated topic for this content. I could set that up along with the work to resolve this issue. If a dedicated topic, do you want it in the Host and deploy node?

[danroth27]

Native dependencies aren't really a deployment concern; they are a development concern. You need to be able to use your native dependencies during development. So I think this deserves a dedicated topic.

[guardrex]

I'll set it up first thing tomorrow morning with the updates to address this issue. Seems like it will be one of our "floating" Blazor topics out in the open Blazor node.

Currently the section Blazor WebAssembly: Use (native) libraries which uses SkiaSharp as an example

The mentioned SkiaSharp.Views.Blazor has the following dependencies

one of the dependencies: SkiaSharp.NativeAssets.WebAssembly packs a static library libskiasharp.a

Questions1

==> for users who are interested to use other native libraries (e.g. TorchSharp.NativeAssets.WebAssembly) in Blazor WebAssembly, we need elaboration on how to create such nuget and what files to be included and how to organize them.

Question2

The TorchSharp native assets are huge. Is there size limit of currently implementation of Blazor WebAssembly for using native libraries?
