The following error shows in devtools:
https://github.com/OmniSharp/omnisharp-vscode/blob/7f128dae95e3281cd49502ed095fbed53a83d6e9/src/coreclr-debug/activate.ts#L79

There should be a normal error indicating what the problem is and maybe even manual steps to fix this.
This happened to me on a few system by now. Every time fixed by luck.
I have removed the extension and reinstalled.
I removed VSCode and reinstalled.
Nothing helped.

Actual behavior

The following error is shown in the console:
[ERROR]: C# Extension failed to install the debugger package

@RandallFlagg What I believe this error message means is that for some reason the C# extension thinks it downloaded and extracted all files, but somehow the debugger is missing.

What do you get from:

dir "%userprofile%\.vscode\extensions\ms-vscode.csharp-1.14.0\.debugger\*.exe"
dir "%userprofile%\.vscode\extensions\ms-vscode.csharp-1.14.0\install.Lock"

[RandallFlagg]

I use the portable option(as expliained here) so the directories don't exists where you mentioned.

Regardless of my above saying the "%extentionLocation%\.debugger folder doesn't exist.
The install.Lock file exists.

[gregg-miskelly]

That is definitely why you are seeing this error. Now we need to try and figure out how we got into this state.

If you delete install.Lock and restart VSCode, does the problem happen again? If so, do you get any other logging from the C# extension?

[gregg-miskelly]

@RandallFlagg are you still seeing this problem? Would you like help, or should I close this?

I have the same issue. I don't have the .debugger directory in "%userprofile%.vscode\extensions\ms-vscode.csharp-1.15.2" and install.lock does not exist in "%userprofile%.vscode\extensions\ms-vscode.csharp-1.15.2".

I have the same issue on OS X 10.11.6

[RandallFlagg]

@gregg-miskelly sorry for the delay. I have found the reasons for this. It happens on 2 different setups I have.

1. VSCode settings are not in the default location
2. VSCode settings are behind a symlink. (default location that points to somewhere else)

Can you confirm?

@ptian @tiomke is one of those your setup by any chance?

My vscode is installed in "C:\Program Files\Microsoft VS Code" but the settings.json is in C:\Users<user ID>\AppData\Roaming\Code\User. How do I correct it? Thanks.

I have this issue on macOS 10.14.3, Visual Studio Code 1.31.1, C# extension version 1.17.1.

@jgfoster The beta version contains some download validation and might fix the problem. You can install it by following the instructions here. Please let us know if this fixed the issue.

@akshita31, I no longer get an error installing the 1.18.0-beta10. Thanks!

[akshita31]

This issue is fixed in the latest beta(1.18.0-beta10) and the corresponding release(1.18.0) which is scheduled next week. I will close this issue now.
