Web Assembly doesn't work after following documentation

[davidgiga1993]

Describe the bug

When following the steps described in the documentation and running the web server using dotnet run the web app can't load due to 404 http://127.0.0.1:62860/_framework/avalonia.js

To Reproduce

Follow the guide, effectively:

dotnet workload install wasm-tools
dotnet new install avalonia.templates
mkdir BrowserTest
cd BrowserTest
dotnet new avalonia.xplat
cd BrowserTest.Browser
dotnet run

Expected behavior

The sample app should work

Avalonia version

11.1.0

OS

WebAssembly

Additional context

The template used <TargetFramework>net8.0-browser</TargetFramework>, but I also tested with net9.0-browser.

I've also noticed that the path described in the documentation under Testing AppBundle locally doesn't seem to be correct (or at least for me this doesn't match up at all, maybe it's related to the issue above?)

Make sure you have up-to-date .NET SDK installed. I.e. latest patch releases.
There were reports of similar problems on older .NET 8 builds.

Yep I actually just installed .net sdk 9 (rc1) when going through the document, so should be latest

FYI - I'm running into a marginally related issue #17036
