I want to use VS code instead of Visual Studio for .Net Framework 3.5 or .Net Framework 4.8 project

I’m transitioning from Visual Studio to Visual Studio Code for .NET Framework 3.5 and 4.8 projects but facing difficulties with:

1. Debugging: Setting up a debugger for seamless support.
2. Resource Files (.resx): Editing/viewing with auto-generation of designer files.
3. DBML Files: Managing these and their designer files effectively.
4. How to execute the Unit tests?

Are there any extensions, workflows, or best practices in VS Code to handle these issues?
