VS Code version: 1.27.2

C# Extension version: 1.16.1

Steps to reproduce

I opened a C# sharp file on a ASP.NET Core project.

I reinstalled Visual Studio Code and Omisharp as well as ASP.NET Core runtimes and SDK and I keep having the same problem.
Problems with Intellisense not working has been something very common ...

Expected behavior

Intellisense to display options after typing a dot ...

Actual behavior

Intellisense is not working ... No options are displayed.

Exception

I checked the developer console and get the following:

[Extension Host] [ms-vscode.csharp] Accessing a resource scoped configuration without providing a resource is not expected. To get the effective value for '[csharp]', provide the URI of a resource or 'null' for any resource.

[Extension Host] rejected promise not handled within 1 second

@mdmoura I think I understand what might be happening. OmniSharp is loading only the API project, hence you are getting complete intellisense support for that project, and for the files in other projects you are getting only basic support(which doesnot look into the project definition).
Can you try "OmniSharp --> Select Project", you should see a drop down with all the project names, and selecting a project would make the intellisense work for it.

We are tracking work related to adding Multi-Root Workspace support here: https://github.com/OmniSharp/omnisharp-vscode/issues/1889.

Been having troubles myself for a week or so. OmniSharp.exe consumes lots of CPU. The joke around the office is that it's mining bitcoins 馃槅

Generally, I've been having to restart VS Code to get it working again. Seems to be related to the upgrade to version 1.16

floyd-may picture floyd-may on 19 Sep 2018

In my case it stops working maybe half of the times I update Visual Studio Code ...

Sometimes, even without updating it and I need to reinstall everything ...

@floyd-may

OmniSharp.exe consumes lots of CPU

Yes, it also happens with me ...

@mdmoura Can you share your "OmniSharp log" and "C#" log. You can find it in the "View--> Output" pane.

I checked the Ominsharp Log and got the following:

Then I opened the Startup file of the ASP.NET Core project "c:\Users\Mig\MyProj.Api\MyProj.Api.csproj" with the following:

    public void ConfigureServices(IServiceCollection services) {
      String name = "Hello";      
      services.AddMvc();
    }

Now intellisense works if I type:

name.

But it does not work if I type:

services.

I do not have a C# log on the VS Code output only Omnisharp Log, Tasks, ...

Is it necessary to do something to enable C# log?

I tried the Quick method in:
https://github.com/OmniSharp/omnisharp-vscode/wiki/Enabling-C%23-debugger-logging

And then I opened the VS Developer Tools and go the following:

/C:/Users/Mig/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/workbench/workbench.main.js:276 [Extension Host] [ms-vscode.csharp] Accessing a resource scoped configuration without providing a resource is not expected.

@mdmoura Do other IDE features work for you? Like are you able to see the Codelens above the method names or the class names? If you do an F12 on the IServices interface do you get some result ?

akshita31 picture akshita31 on 20 Sep 2018

@pgmitche Can you create a basic "dotnet new console" project and open it in vscode? Does anything work for you there ?

@akshita31

Do other IDE features work for you? Like are you able to see the Codelens above the method names or the class names? If you do an F12 on the IServices interface do you get some result ?

Yes, I am able to see Codelens above the method names and the class names.
If I hit F12 over IServiceCollection I get the message "No definition found for IServiceCollection".

I have 3 ASP.NET Core web projects on my Solution / VSCode workspace.

There is one project where Intellisense works for services variable and when I hit F12 over IServiceCollection I am taken to [metadata] IServiceCollection. That projects is the API.

The API is the first project on the workspace and on Omnisharp log it is the first one being referenced by Ominsharp when it startups ... Check my previous post.

It seems it is working for the first project but not for the other ones ...

This is the definition of the project where Intellisense is working for services:

They are identical and both build fine so I have no idea what is going on ...

@mdmoura I think I understand what might be happening. OmniSharp is loading only the API project, hence you are getting complete intellisense support for that project, and for the files in other projects you are getting only basic support(which doesnot look into the project definition).
Can you try "OmniSharp --> Select Project", you should see a drop down with all the project names, and selecting a project would make the intellisense work for it.

We are tracking work related to adding Multi-Root Workspace support here: https://github.com/OmniSharp/omnisharp-vscode/issues/1889.

I am having the same issue, omnisharp cannot load any of my projects (I've tried reinstalling dotnet sdk, vscode, csharp-extension -- on both windows and mac os).

I don't have the same error message as the guy above but on my Mac it's telling me that it can't fint "mscorlib.dll".
And on Windows it's telling me it can't find the .NET SDK.

@akshita31 I've tried the "Omnisharp --> Select Project" route, but it just gives me the same error message

monefeldt picture monefeldt on 20 Sep 2018

@monefeldt Can you post the output from "OmniSharp log" ? Also, do you get the same errors if you run a basic "dotnet new console" application ?

akshita31 picture akshita31 on 20 Sep 2018

@akshita31

Can you try "OmniSharp --> Select Project"

So I selected the Auth project on Ominsharp and now Intellisense works on it ... but stopped working on the API project.

Shouldn't work in all projects without the need of changing on Omnisharp?

A suggestion:

Shouldn't the omnisharp.projectLoadTimeout default value be increased?

Better would be to improve Omnisharp CPU consumption to run faster ...

@mdmoura If you load a solution that contains all the projects, then intellisense will work for all if them, however omnisharp currently doesnt support loading multiple projects in a multi-root workspace.

@tejalbarot Can you post the complete "OmniSharp log" and also the output of dotnet --info ?

akshita31 picture akshita31 on 21 Sep 2018

@akshita31

I organize the projects in a very common way, e.g.:

project.sln
project.code-workspace
/src
   /api-project
      api-project.csproj
   /auth-project
      auth-project.csproj
/test
   /api-test-project
      api-test-project.csproj
   /auth-test-project
      auth-test-project.csproj

In Visual Studio Code I load the Workspace file ...

Any ETA for when Omnisharp will be compatible with a Visual Studio Code Workspace?

mdmoura picture mdmoura on 21 Sep 2018

Im bumping this thread, the same issue as the ones listed above is affecting all the members of my team. We've all tried reinstalling everything (Vscode, omnisharp, .net core sdk/runtime) but nothing seems to help us. We've tried doing a plain new console app but the problem persists no matter the form our C# projects take.

Latest output from Omnisharp on my machine, now it can't find mscorlib.dll

@monefeldt I am not sure why it could not find that dll. Could you try setting "Omnisharp.path-->latest" and restarting the omnisharp server

Thanks, that did the trick!

Another troubleshooting strategy to try if none of the above works out is uninstalling Mono. I also experienced a sudden disappearance of Intellisense after pulling changes to one of our enterprise repos that included an upgrade from ASP.NET Core 2.0 to 2.1. Strangely, at the same time, Intellisense was working fine in another C# project repo running ASP.NET Core 2.2.

For the project in question, I was puzzled to see successful logs for each reboot of the Omnisharp server as well as perfectly clean builds and runs. The puzzlement increased as I compared these Omnisharp logs to those from 2.2 project and found them practically identical.

Upon uninstalling Mono, the one detail that changed is _how_ Omnisharp started. Now it boots up from a shell script located at ~/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.18/run. Previously, Mono itself was booting the server from the executable at ~/.vscode/extensions/ms-vscode.csharp-1.19.0/.omnisharp/1.32.18/omnisharp/Omnisharp.exe.

Other troubleshooting I attempted to no avail:

  • dotnet clean / Deleting bin and obj directories
  • Updating launch.json to point at the proper bin/Debug/netcoreapp2.1 build directory
  • Wiping my local nuget cache
  • Restarting Omnisharp
  • Uninstalling and reinstalling VS Code, as well as bumping back a version from 1.33.1 as the breakage coincided oddly with the March 2019 update
  • Uninstalling and reinstalling the C# VS Code extension, as well as bumping back a version from 1.19.0 given other users' reports of said version interfering with Intellisense for certain projects
  • Adding a global.json file at project root to override default utilization of latest .NET Core SDK (mine was 2.2.105) and run instead using 2.1.302 in concert with the project's version
  • Wiping/rebuilding the project .sln file

Specs:
VS Code 1.33.1, C# Extension 1.19.0, MacOS High Sierra 10.13.6.

I'm using VS remote Containers, which opens a workspace. There are 3 slns in the directory. I open the one that links to the right project.

Intellisense doesn't work.

Here's what's now showing up in the logs which makes no sense because it's running in docker on a linux container using the default.net core sdk dev container

    Failed to load project file '<xyz>'.
