(...)
private static getExactRuntimeId(distributionName: string, distributionVersion: string): string {
switch (distributionName) {
case 'ubuntu':
if (distributionVersion === "14.04") {
// This also works for Linux Mint
return LinuxRuntimeId.ubuntu_14_04;
}
else if (distributionVersion === "16.04") {
return LinuxRuntimeId.ubuntu_16_04;
}
else if (distributionVersion === "16.10") {
return LinuxRuntimeId.ubuntu_16_10;
}
break;
(...)

Is it safe to make another else if to my current version, returning LinuxRuntimeId.ubuntu_16_10??

Thanks,

@jcasimiro that depends on if Ubuntu 17 is backwards compatible enough with 16.10 that .NET Core 16.10 will actually work (in the past, they haven't been). Have you tried running a basic 'hello world' app using the 16.10 .NET Core by chance?

[jcasimiro]

Hello,

Yes the application runs fine, only the debugger is not working.
I'm new to this project, but i read somewhere that i could define by configuration what version of linux i want to use, is this correct?

Thanks

[gregg-miskelly]

@jcasimiro The next version of the C# extension will support that, but our current version doesn't yet. Let me send you a private version with the new support for specifying the runtime id and you can give that a try.

[jcasimiro]

Thanks, you're the man. ;)

[gregg-miskelly]

There is a private attached to this comment. Please:

1. Download csharp-1.9.0-beta2-private.zip
2. Rename the extension from '.zip' to '.vsix'
3. Follow instructions on https://github.com/OmniSharp/omnisharp-vscode/wiki/Installing-Beta-Releases for installing it.
4. Let me know how well things work for you

Hope this helps.

Gregg it worked!!! Thank you man.

This was the output after installation:

Updating C# dependencies...
Platform: linux, x86_64, name=ubuntu, version=17.04

Finished
If 'ubuntu' is binary compatible with a Linux distribution officially supported by .NET Core, you may be able to resolve this by setting 'csharp.fallbackDebuggerLinuxRuntimeId' in 'File->Preferences->Settings' and restarting VS Code.

Obviously I changed the setting.
Thank you!! Solved!!

[gregg-miskelly]

@jcasimiro Excellent! Thanks for trying. I will close this for now then.

[alikzao]

I was not helped by this recipe unfortunately.

[gregg-miskelly]

@alikzao the problem is that true is not a valid value for fallbackDebuggerLinuxRuntimeId. If you are on Ubuntu17, you likely want ubuntu.16.10-x64. There is autocomplete to help you type in a valid value.

[SuddenGunter]

@gregg-miskelly Thank you, it works.
And it's not required to install a beta version of OmniSharp because the latest one (v1.11) works fine.
You just need to add "csharp.fallbackDebuggerLinuxRuntimeId": "ubuntu.16.10-x64" and everything will be ok.

@gregg-miskelly its not working pleaze provide me exact steps what to do to debug code in ubuntu 17.04 .net core c#

[gregg-miskelly]

I am on vacation this week, but at this point I would recommend following instructions from the wiki on installing the most recent beta, as that has official support and is just about to go out on the release channel.
