I also noticed that my coworker has the same problem which also began this morning, we have the same issue on all of our projects.

icyh4mmer picture icyh4mmer on 11 Sep 2018

Was having the same issue after updating the extension to 1.16.0 version this morning. Reverting extension back to 1.15.2 resolved the issue.

Here is .vsix installer from this repository in case you need a quick workaround.
csharp-1.15.2.zip

@icyh4mmer: Your issue is different than the one filed here. Your log looks more like https://github.com/OmniSharp/omnisharp-roslyn/issues/1094.

DustinCampbell picture DustinCampbell on 11 Sep 2018

@TiredOfCoding, @Ghostbird, @vscodeguru : Glad you were able to roll back and unblock yourselves.

DustinCampbell picture DustinCampbell on 11 Sep 2018

We believe we have identified the cause of the "GetReferenceNearestTargetFrameworkTask" issue and we've created a beta of the C# extension that includes the fix. Please install the beta VSIX (https://github.com/OmniSharp/omnisharp-vscode/releases/download/v1.16.1-beta1/csharp-1.16.1-beta1.vsix) and let us know if that resolves the problem

@rchande A Unity project loads without fails and IntelliSense works too. Seems like the issues resolved, thanks.

@rchande Sorry for the late reply, I tried both version 1.6.1-beta1 and 1.6.1, but the most recent version that works for me is 1.5.2.

@Ghostbird Can you:

  • File a new issue
  • Include your omnisharp log from 1.16.1?

Thanks!

@rchande Installing the 1.16.1 beta fixed the issue for me. :)

The exception indicates that MSBuild couldn't locate the Microsoft.NET.Sdk.Web SDK from the .NET Core SDK. I just tried but wasn't able to reproduce. Here's what I did:

  1. Install Fedora 28 workstation
  2. Install VS Code from a terminal window using these steps: https://code.visualstudio.com/docs/setup/linux#_rhel-fedora-and-centos-based-distributions
  3. Install .NET Core SDK using these steps: https://www.microsoft.com/net/download/linux-package-manager/fedora28/sdk-2.1.402
  4. Create a new project with dotnet new web.
  5. In the project's folder, run code with code .

The project loaded without error. 馃槥

I had this problem recently, I thought I had everything installed even mono, but I didn't have mono-complete installed just a few packages it seems, it solved my problem. People could try that and see if it solves thier problems.

sergol7788 picture sergol7788 on 18 Oct 2018

Hi there, sorry for the long absence. I managed to fix the issue. Placing the log level in "trace" was really helpful. By the way, I am no longer using fedora. I will post my dotnet --info file in a following post.
It seems the problem was with the msbuild folder inside my .vscode folder in home. Omnisharp sets some default paths inside ~/.vscode/extensions/ms-vscode.csharp-1.17.1/.omnisharp/1.32.8/omnisharp/msbuild/15.0/Bin/ when initiating for the following assets:

  • Microsoft.NETCoreSdk.BundledCliTools.props
  • Microsoft.NETCoreSdk.BundledVersions.props
  • Sdks folder

All these are obtained when you install the dotnet sdk from the repositories. In my case, the installation is located in the /opt/dotnet folder. So, all I did was to create symbolic links from the folder and files in the installation to where the paths in the error log indicated.

I am not sure why these assets were not present in the msbuild folder, though.

Before doing this I also tried to see if there was any setting I could change so Omnisharp would be aware of the files but I couldn't find any. Maybe this could a possible fix to the issue.

I hope this helps to anyone having this problem and I am looking forward to hear your comments.

You know you can simply just install the .NET framework developer pack if you don't have it and it instantly worked for me and i also can have the latest updates too. https://www.microsoft.com/en-us/download/details.aspx?id=56119

Same issue on Ubuntu 20.04, dotnet 3.1.201, c# extension 1.21.17.

The downgrade to 1.15.2 worked for me though.

  1. Download the latest framework developer edition, https://dotnet.microsoft.com/download/visual-studio-sdks (Currently 4.8)
  2. Edit the files Assembly-CSharp.csproj and Assembly-CSharp-Editor.csproj in your unity root folder
  3. Update the framework settings in the files to the one you downloaded (currently 4.8)
  4. Save & close vscode
  5. Re-open

It worked for me

C# for Visual Studio Code v 1.22.1
VSCode v 1.46.1

Thanks to @Ghostbird @w1dg3r @Noeyedeerwhy

Download:

Then just install the last version of C#

So i did all the steps from here https://github.com/OmniSharp/omnisharp-vscode/issues/2509#issuecomment-420318250, but it didn't work for me. And after 3 hours of trying to fix the problem, i found that my Avast was blocking Omnisharp.
When I disabled Avast it worked. So if anyone of you use Avast, try to disable it forst, maybe that is the problem.

Stop using avast.... This software pickaps your data, contacts, information about sites visits and send it to owners for seling this on targeting markts. Use bitdefender or avira. Free fast and secure without targeting.
