VS Code version:

Version: 1.43.2
Commit: 0ba0ca52957102ca3527cf479571617f0de6ed50

Node.js: 12.8.1
V8: 7.8.279.23-electron.0
OS: Linux x64 4.15.0-91-generic

C# Extension version:
1.21.15

Steps to reproduce

Opened a folder with sln file and C# projects in it. Added the following launch configuration:

    "configurations": [
        {
            "name": ".NET Core Launch (console)",
            "type": "coreclr",
            "request": "launch",
            "preLaunchTask": "build",
            "program": "${workspaceFolder}/trigger_management/bin/Debug/trigger_management.exe",
            "args": [],
            "cwd": "${workspaceFolder}/trigger_management/bin/Debug",
            "console": "internalConsole",
            "stopAtEntry": false,
        }

Clicked Run -> Start Debugging.

Expected behavior

The binary is executed

Actual behavior

Got the following message in debug console:

-------------------------------------------------------------------
You may only use the Microsoft .NET Core Debugger (vsdbg) with
Visual Studio Code, Visual Studio or Visual Studio for Mac software
to help you develop and test your applications.
-------------------------------------------------------------------

[WardenGnaw]

Important note

This message is NOT an indication of a problem. It is always printed when the debugger starts.

More info

If the debug console never shows any other messages, and otherwise it seems like your program is never starting (ex: a breakpoint on the first line of Main never hits) it could be that the debugger is failing to start, but VS code isn't showing the error. Please open a new issue. As part of this new bug, please include a debugger log. You can enable logging by adding this to your launch.json:

"logging": {
   "engineLogging": true
}

I think I'm having the same issue, these are my logs;

@ErtanM are you seeing some sort of problem?

That log indicates that the debugger successfully started and launched the app, and the app is just sitting there. If you are expecting the app to do something, you might want to hit the 'pause' button to break into your app and see where it is stuck.

[jakubsuchybio]

Same problem here with logs:

@jakubsuchybio can you elaborate? What is happening/not happening that you are expecting?

[jakubsuchybio]

@gregg-miskelly I also created issue ticket in cake-vscode extension repo.
There is also repro steps.
Basically I just have repo with cake-build script. If you open it with vs code, install cake extension you will get codelens for Tasks in .cake scripts. Those code lenses are run task and debug task. Also there is also .vscode/launch.json from which I can F5 debug that script, which works. But running debug through that debug task code lens crashes with error mentioned in my previous post with log.

[gregg-miskelly]

Thanks @jakubsuchybio, to make sure I understand, you are talking about the following message? That actually isn't an error - it is just license text.

-------------------------------------------------------------------
You may only use the Microsoft .NET Core Debugger (vsdbg) with
Visual Studio Code, Visual Studio or Visual Studio for Mac software
to help you develop and test your applications.
-------------------------------------------------------------------

[gregg-miskelly]

I am going to close this issue for now, because I think it is confusing people. If anyone is experiencing a problem (and not just confused by the license text) please open a new issue.

[jakubsuchybio]

@gregg-miskelly Well in the log near the end there is

The program '[25684] Cake.dll' has exited with code 1 (0x1).

So it crashed because of some other reason. I have concrete repro, so can we investigate somehow further?

Edit:
Hmmm thinking about this, it might definitelly not be in omnisharp, but in Cake. I will follow up in their repo further.

[gregg-miskelly]

@jakubsuchybio sounds good. Let us know if you find this is a debugger problem.

[Iron-E]

I'm getting this issue too. By issue, I don't mean that the message is printing— I mean that the message is the only thing that happens. I can launch debugging after creating a simple test that only involves simple number addition and subtraction and it does not execute a single thing. No breakpoints, and no end. I cannot pause, and restarting the debug session yields an error:

WARNING: Unable to connect to debuggerEventsPipeName '/home/iron-e/.vscode-oss/extensions/ms-dotnettools.csharp-1.21.17/.TestDebugEvents-581800'. Cannot assign requested address /home/iron-e/.vscode-oss/extensions/ms-dotnettools.csharp-1.21.17/.TestDebugEvents-581800

I'm having issues with running tests in OmniSharp.vim too, I'll file that issue in the proper location though.

I have also enabled logging as per the previously stated instructions, and there does not seem to be any further output other than the legal message and this:

[info]: OmniSharp.DotNetTest.DebugSessionManager
        Debug session started.
[info]: OmniSharp.DotNetTest.DebugSessionManager
        Debug session ended.

in the output window (the "ended" appearing after manually stopping the debug session after waiting several minutes to see if it would resolve itself).

Edit:

Could this be related to a [TestFixture]'s constructor failing? I've posted an issue here and it seems like whenever there is a failed constructor (before tests begin to execute) OmniSharp exhibits strange behavior.

[Perustaja]

Same issue here. I know it's an odd problem to describe. I am using Arch Linux. I can run and debug the same projects in Windows just fine, both .NET Core and ASP.NET Core. Using the same project and extensions on Arch, my debugger just hangs after displaying the licensing message regardless of whether it's a simple console app or a webapi with or without tests. Cannot debug tests either if they are present.

In fact adding the logging statement to launch.json still results in just that message being printed for me. Everything runs properly, just debugging support doesn't. Don't want to bloat the issue but here is my dotnet --info output

[gregg-miskelly]

@Perustaja if you installed VS Code from the Arch package repository: the problem is that you have the OSS version of VS Code, and the C# debugger is not licensed to work in non-Microsoft products. Please install VS Code from Microsoft if you would like to use the debugger from this extension.

If that is not your problem: please open a new issue. Unfortunately this issue is very generic, so, unless you look at a debugger log to see what failure is being reported, it is hard to guess if one person's problem is the same as another. So I will lock it to prevent further comments.
