[Blazor] [WASM] SharedArrayBuffer is not defined #20430

Closed steven-hack closed 4 years ago

steven-hack commented 4 years ago

After upgrading packages to the latest preview version I got the following error when trying to run the application in Firefox:

ReferenceError: SharedArrayBuffer is not defined dotnet.3.2.0-preview4.20181.1.js:1:123642

Tried removing cache, local files etc. but that didn't matter. When opening the application in Edge or Chrome it works fine.

I am developing on Windows 10 using Visual Studio 2019 Preview 2.0 (Version 16.6.0) Firefox version is 74.0 (64-bits)

I did some investigation which packages seemed to cause the problem. It appears to be both Microsoft.AspNetCore.Components.WebAssembly 3.2.0-preview4.20181.13 Microsoft.AspNetCore.Components.WebAssembly.Build 3.2.0-preview4.20181.13 (my experience is that using different versions of these packages you're bound to get trouble anyway, so I kept those two versions in sync)

Downgrading the packages back to version 3.2.0-preview4.20181.2 solved the issue. Anything between those versions (3.2.0-preview4.20181.13 and 3.2.0-preview4.20201.3) give the same problem.

@IIStevowII thanks for contacting us.

I'm not sure how you are getting a preview4 version since we haven't released it. Are you manually updating to the nightly builds?

steven-hack commented 4 years ago

Yeah, should have mentioned that. I'm doing a hobby project and added the nightly feeds in order to get the latest builds.
