blazor.web.js missing from publish output

Describe the bug

I have Blazor 8 Web App which runs fine in development. After publishing the app using dotnet publish, I've noticed all interactivity is broken because blazor.web.js is not included in the publish output. What am I missing?

Update: I've checked with a fresh Blazor 8 Web App project created with VS 17.8 RTM and blazor.web.js is also absent from publish output.

Update 2: Even by manually copying over blazor.web.js to the server's deployment folder, I cannot get interactivity to kick in once deployed. In development I can observe dotnet.js being loaded when hitting a page containing interactive components and bootstrapping WASM via blazor.boot.json. In production dotnet.js is not being loaded even though it's been deployed.

@oliverw thanks for contacting us.

blazor.web.js is never a file on disk, it's embedded at build time in the Endpoints.dll, that's why it doesn't show up on disk.
