How does one disable webassembly in Microsoft Edge

Question

I've come across this guide as to how to disable webassembly on browsers.
https://github.com/stevespringett/disable-webassembly

I've tried to disable it by going to "edge://flags" and settings all flags that contains the word WebAssembly to disabled (e.g . "Experimental WebAssembly", "WebAssembly baseline compiler" etc )

However when I browse to Calculator (an example of c# winforms in the browser) , I still see wasm files and dll's being downloaded and the wasm calculator app still works in the browser.

Does anyone perhaps know how one disables the WebAssembly feature/module in Microsoft Edge

Hi @0x0-dot-co-dot-za

I notice that you're using Edge Chromium so you can disable WebAssembly in Edge just like the Chrome/Chromium way in the link you provide:

Launch Edge with the following command-line argument: --js-flags=--noexpose_wasm.

You can add the argument after the Edge target in the shortcut properties, then click Apply and OK to save the change:

After the change, when you run Edge again, WebAssembly is disabled:
