Could not load file or assembly 'Microsoft.Bcl.AsyncInterfaces' on extension startup

Today when I start VS I'm getting this error and the Smart Command Line window no longer shows up.

I tried reinstalling and restarting but still happens

I'm seeing this as well as of yesterday

Edit: Rolling back to 2.6.0 fixed things.

Hi, thanks for the report, which version of VS are you using?

[n-zer]

I'm on VS2022, 17.4.1

I can't reproduce the issue but I have a (guess) fix ready if you want to try It out. I have it uploaded in 3 minutes.

Here it is: v3.0.3

[djfooks]

I'm on 3.1.0 now . Looks like it is working again. Thanks!

Version 3.1.0 is the same as the old 2.6.0 because the Visual Studio Marketplace does not allow you to revert back to an older version. It would be great if you could still try v3.0.3 (because that's the new version with new features) and tell me if it works or if your error still persists?
