VS Code and TFVC for source code management

Team,

I am trying to use Visual studio code(1.57) for class development and for compiling classes (intersystems tools extension) . It works.

Now, i would like to use TFVC (Team Foundation Version Control) for source control.  

I can see download option where i can manually download the Namespace as folder and classes as files.

Since whenever i save the file, it directly pushes the change to remote system. I am not sure where the local workspace is.

How to configure VS Code to track my changes and Check In / Check out the code.

If there are other ways to achieve source code control in TFVC please let me know

looking for some help here

Thanks.
