Expected behavior

Actual behavior

this came first:
[ERROR] Could not locate an OmniSharp server that supports your Linux distribution.

OmniSharp provides a richer C# editing experience, with features like IntelliSense and Find All References.
It is recommend that you download the version of OmniSharp that runs on Mono using the following steps:
1. If it's not already installed, download and install Mono (https://www.mono-project.com)
2. Download and untar the latest OmniSharp Mono release from https://github.com/OmniSharp/omnisharp-roslyn/releases/
3. In Visual Studio Code, select Preferences->User Settings to open settings.json.
4. In settings.json, add a new setting: "omnisharp.path": "/path/to/omnisharp/OmniSharp.exe"
5. In settings.json, add a new setting: "omnisharp.useMono": true
6. Restart Visual Studio Code.

So I followed the instructions. my setting.json:
// Place your settings in this file to overwrite the default settings
{
"omnisharp.path": "/home/chrx/Omnisharp/Omnisharp.exe",
"omnisharp.useMono": true
}

I get this error on startup:

Invalid value specified for "omnisharp.path" ('/home/chrx/Omnisharp/Omnisharp.exe).

[Neoakb]

I changed Omnisharp.exe to OmniSharp.exe in the path, that still didn't fix it.

[DustinCampbell]

The entire path is case-sensitive. Also, what version of Mono do you have installed?

There's a screenshot with mono -v, VC settings.json, and the file manager open to the Omnisharp install. I did fix the syntax error that's present in the json

Mono is working fine. I can run the hello test just fine.

I get this error when I run a simple .cs file though rightclick -> Run Code
(using https://code.visualstudio.com/docs/runtimes/dotnet to create a new dotnet project)

[Running] scriptcs "/home/chrx/Documents/TestingOmni/Program.cs"
/bin/sh: 1: scriptcs: not found

[Done] exited with code=127 in 0.031 seconds

While testing different ideas, I found by renaming Omnisharp (the one highlighted in the file manager) to Omnisharp.exe I now get this on startup:

Starting OmniSharp server at 11/1/2016, 12:27:50 AM

Path: /home/chrx/Omnisharp/OmniSharp.exe
PID: 9815

Cannot open assembly '/home/chrx/Omnisharp/OmniSharp.exe': File does not contain a valid CIL image.
[ERROR] Error: Failed to start OmniSharp

I still get the same error when trying rghtclk->Run Code.

I get the same as the above when changing the omnisharp.path to /home/chrx/Omnisharp/OmniSharp while I changed OmniSharp.exe back to OmniSharp

[DustinCampbell]

When you say that you right-click a file and choose Run Code, I'm actually not clear on where that is. I've been unable to find a "Run Code" command in VS Code. Perhaps that is coming from some other extension?

Could you try the latest v1.5-future-preview1 release of the C# extension. I suspect this may work better.

Do the following to install the new extension:

1. Download the .vsix for the extension at the link above.
2. Open Visual Studio Code.
3. Select Preferences->User Settings from the menu and then removing the "omnisharp.path" and "omnisharp.useMono" settings from the settings.json.
4. Select View->Extensions to display the Extensions pane.
5. In the Extensions pane, click on the little gear icon next to the C# extension and select "Uninstall". Allow Visual Studio Code to reload.
6. In the Extensions pane, click on the [...] at the top-right corner of the pane and select "Install from VSIX...". Pick the .vsix you downloaded and then allow Visual Studio Core to restart.

[Neoakb]

That's from formulahendry.code-runner

He's output after installing the new version (code-runner disabled just incase):

Tried to uninstall/reinstall, but that didn't change anything.

EDIT:
Here's the omnisharp log as well:

[gregg-miskelly]

@Neoakb can you give us the output from cat /etc/os-release?

@chuckries looks like we have some (multiple?) sort of issue here as it is trying to download multiple versions of the debugger, and then CentOS is giving a 404.

[gregg-miskelly]

@Neoakb one last question - are you trying to do .NET Core development or mono? If .NET Core, are you finding that the Ubuntu 16 version of .NET Core works well enough? Or are you using some sort of other version?

[Neoakb]

I am using this course to learn C# and wanted to be able to work while I was away. With .NET Core it seems like I'll be able to develop on and for most systems.

https://mva.microsoft.com/en-US/training-courses/c-fundamentals-for-absolute-beginners-16169?l=Lvld4EQIC_2706218949#

I'm 'technologically inclined', but I'm still a novice programmer.

[gregg-miskelly]

@Neoakb got it. We haven't tried Gallium at all, but I can give you a test version of the C# extension later today which causes it to treat Gallium like Ubuntu 16 and you can see if that works for you.

[gregg-miskelly]

NOTE: The CentOS failure is now being tracked with #910. Better handling of unknown Linux distros is tracked with #911. This bug will just track trying to get Gallium OS to work.

[gregg-miskelly]

@Neoakb please try this:

1. Download the file: csharp-1.5.0-dev-galliumos.vsix.renamed.zip
2. Remove the '.renamed.zip' part of the extension
3. In VS Code: View->Extensions
4. Click the '...' to bring up the additional command menu and select 'Install from VSIX...', and navigate to the downloaded file
5. Confirm that downloading assets succeeds
6. Try debugging and see if that works (you can hit breakpoints, and the locals window shows your variables)

Intellisense seems to work. I think we might be good. Don't know about those missing symbol files though. (TBH I know nothing about them either way.)

[gregg-miskelly]

@Neoakb the 'Cannot find or open the symbol file' is normal for system assemblies. There is an issue to give that a nicer message so it doesn't sound like a problem, but we haven't fixed it yet.

Were you able to hit a breakpoint and inspect values?

[Neoakb]

I was just using a simple hello world to test. want me to test specific code or just make some variables and change them, etc.

[gregg-miskelly]

It would be enough to just set a breakpoint on the 'Console.WriteLine' line and verify you can inspect 'args'.

[DustinCampbell]

me <- thrilled that IntelliSense works!

[Neoakb]

Just tested and it worked just fine. Looks like I'm set now. Anything I should keep an eye on? When to update back to the normal C# extension and what not.

[gregg-miskelly]

@Neoakb The only things to keep in mind are:

• We are out of time for this to make 1.5.0, so when that comes out (probably on Monday) do NOT upgrade to it. But you have 99.99% of the same bits, so that shouldn't be a problem.
• When 1.5.1 or 1.6 (whatever we call the next release) comes out, you should be able to safely upgrade. You may want to explicitly remove the ~/.vscode/extensions/ms-vscode.csharp-1.5.0-dev-galliumos folder to make sure that VS Code prefers the released version.

[DustinCampbell]

@gregg-miskelly: What change is needed?

[gregg-miskelly]

gregg-miskelly@cbe1e20

[Neoakb]

Awesome! Thanks for the help. Hope I helped somehow!

[DustinCampbell]

merge it 😄

[DustinCampbell]

The fix in the release branch now. Thanks @Neoakb! It'll be in 1.5.
