'Unable to generate assets to build and debug. OmniSharp server is not running

On Visual Studio (VS) Code, coding on C#. I'm trying to generate assets to build and debug and I'm getting the following error message: Unable to generate assets to build and debug. OmniSharp server is not running.

I'm running:

  • .NET version 3.1.301
  • Windows 8.1
  • Visual Studio Code 1.46.1 (user setup)
  • Powershell 5.1

So far I've tried unistalling VS code and the C# extention, I updated the omnisharp.path to latest at settings.json and updated the powershell version.

The code I'm trying to generate the assets for build and debug does run, so I'm uncertain where else I should look for the source of the problem.

If you require any more details feel free to ask

Ended up discovering the issue. I needed to add a PATH variable to C:\Windows\System32 in the System Variables. Now it works as intended.

Adding the variable depends on your Windows version. You should be able to find guides on adding Paths to your Environment Variables. Here's Microsoft's guide.

As for which path variable you need to add it'll look something like: C:\Windows\System32\WindowsPowerShell\v.1.0

Install the C# Extension, once installed click on the arrow on the side of the uninstall button and then click install another version. First I tried one from 2 months ago, it did not work, then I tried one from 6 months and it worked perfectly!

Solution 5:[5]

  1. Added omnisharp.json file to the root folder with below content:

    { "msbuild": { "useBundledOnly": true } }
    
  2. Select the Command Palette using Ctrl + Shift + P and select the option "OmniSharp: Restart Omnisharp"

  3. Using the Command Palette, select the option "NET: Generate Assets for Debug and Build"

  4. The launch.json and tasks.json files will be added under the .vscode folder

  5. Now you should be able to debug your code

This solution worked for me.
