[Error - 7:15:30 a.m.] Connection to server got closed. Server will not be restarted.

Steps to reproduce

Seems to happen when editing .cshtml (Razor) views. No error pops up, but I notice the issue because Razor Intellisense stops working. If I check the logs, I see "Connection to server got closed. Server will not be restarted"

Expected behavior

Razor to be happy

Actual behavior

Razor crashes repeatedly, Intellisense stops working

Additional context

Sometimes (but not always) restarting Omnisharp temporarily fixes the issue. This error also happened on Linux Mint 20.3 before I updated to 21, and also in several previous versions of VSCode (i.e. not limited to my current version).

[WatchDogsDev]

It's because of openssl version.

A workaround is setting this environment variable before running vscode:

export CLR_OPENSSL_VERSION_OVERRIDE=1.1

But is there anyway to support the openssl 3 and fix it ?

[allisonchou]

Hi all! We released a new version of the C# extension earlier today (v1.25.4) which should address this problem.

@dibarbet Could you please close out this issue?
