OmniSharp log

Steps to reproduce

• (re)Start VSC
• Open a .cs file

Expected behavior

• allowing me to edit/run/debug with all features enabled.

Actual behavior

• It starts download omnisharp/debugger etc.

This issue has been reported here before but the ‘fixes’ there did not help. I’m not behind a proxy (I am reporting this on another connection than my home connection for instance and it happens here too) and it happens on win/lin/mac (all the same VSC version and dotnet runtime; I develop on all 3).

My connection is fast enough so it’s not a real bother, but it seems a bug as it definitely did download before and it works fine once downloaded, so why does it download again?

This is by design. 1.35.4-beta.18 in your log suggests that you have opted into beta builds of OmniSharp by setting "omnisharp.path": "latest" in your VS Code settings. There is a new prerelease build on every merge to master, which can be multiple times a day (not to mention it is highly likely that these CI builds are unstable, as by definition they are not always ready for the release, so your experience can be very poor).

It is not recommended to use this setting for longer than a short while (e.g. to verify a specific bug fix). Please remove that setting to prevent OmniSharp beta builds to be constantly downloaded.

Thank you @filipw, it worked despite the fact that I don’t remember setting this before. But indeed I was using "omnisharp.path": "latest". Nonetheless, it’s confusing that “latest” subscribes to beta channels. IMO it should have another flag for this.

It also bothers me that the extension tries to download it several times if I open another instance while it’s still downloading. It should have a lock file to instruct new instances that a download is in place.
