VSCode C# setup

Follow these steps to configure a C# development environment using VSCode (Code-OSS variant) with the Free OmniSharp extension.

This setup has been tested on Arch Linux with the following package versions:

• code 1.70.2-1
• dotnet-sdk 6.0.8.sdk108-1

Step-by-step procedure

1. Install dotnet sdk and runtime

   • Arch Linux setup:

     sudo pacman -S dotnet-sdk
     

2. Make a directory anywhere you like. Go inside and use dotnet tool to create a sample project with console template:

   mkdir <ProjectName>
   cd <ProjectName>
   dotnet new console
   

   Note: this folder can be deleted later, it is just an example to test if the extension is working

3. Open the editor inside the project folder

   code .
   

4. Install free-omnisharp-vscode extension for C# development

5. Open Program.cs file

   • Note: this step is just to force extension to download OmniSharp implementation

6. Wait until OmniSharp dependencies get installed (it takes time)

7. If editor asks about adding build & run targets, say yes

   • It can also be enabled later inside Run & Debug tab

8. Press F5 to build and execute the example code

   • Breakpoints are supported, add them to the left of the code
   • Open Run & Debug tab to see variables and watch expressions

9. Now the editor is configured and new projects can be created using dotnet tool (like in step 2)

Happy hacking! 🐱
