Ran into the same issue, but it wasn’t in the browser cache, it was in the CDN cache (Cloudflare in my case). Don’t forget to purge the cache.

Good to know @pranavkm thanks! My only hesitation though is won’t that hurt us with those large AOT payloads?

Why do you use AOT? In my test, it is working also without it

I’m just asking if the HTTP headers prohibited caching, wouldn’t that make it slower for users to download the application after the first visit? I just mention AOT because it adds significant file size.

@erossini do you also mind including the obj\project.assets.json for this file? It might be one of your references is causing an older version of blazor.webassembly.js to be used, instead of the 6.0.0 version, and the resolved package references might give us some hints. Alternatively, if there’s a minimal app you could share with us that reproduces the problem, that would be great.
