Omnisharp-vscode: Make OmniSharp "latest" more reliable

[johnnyasantoss]

I'm using the settings "omnisharp.path": "latest" and my VS Code can't download the latest version and it might be related to the CDN that provides the download files.
I've search a bit and found that this already happened a few times (#2681, #2738 & #2741).

Omnisharp Log:

Error occured in loading omnisharp from omnisharp.path
Could not start the server due to Error: 404

C# Log:

I too am experiencing this as of today. I suspect this is related to the CDN. even using older specified versions produces the same result.

Today it is working 🤔
That's a very weird behavior for an automated process (deploy to CDN)

@johnnyasantoss This is annoying and we are working on to make the OmniSharp release more reliable

Thank you @akshita31 😃

Omnisharp has stopped working for me after installing (and removing) the .NET Core 3.0 preview a few weeks ago, and using "latest" was the only way I could get it to work (re-installing the C# vscode extension didn't help).

Now (since yesterday) I can't even download the "latest" build. Thus, I am currently completely unable to use Omnisharp because of this issue.

Same. It's infuriating that VS can't cache a version.

[NTaylorMullen]

Could have a 12-24 hour delay after receiving a new "potential latest" to then promote it to a latest available version. I'd be shocked if cdns didn't pick that up by then. Easy hackish fix 😁

I restarted the build, and the latest is available now - sorry for the trouble.

[FomTarro]

Seems to be down again. Was working for most of this evening, but the 404 error has returned. Is there really no way to cache this? Seems weird to require server auth just to use an IDE.

Or maybe I misunderstand.

You guys can check for all available version here : https://roslynomnisharp.blob.core.windows.net/releases?restype=container&comp=list

The latest beta version available for windows is 1.32.12-beta.51 so set "omnisharp.path": "1.32.12-beta.51" do the trick and allow you to continue your work while waiting for the fix.
