I have added the remote intersystems servers with nameservers in VS Code. 

I can view/edit/Import and compile the class files in VS Code from my local system through workspace as shown in below screenshot.

I need this workspace to be mapped to TFS source control to track the code changes and also to Check IN/OUT to repository.

Thanks for your replied. I have tried with 

1. TFS extension for Visual Studio Code
2. TFVC for VS Code

Configured the vscode-tfvc.tfExePath also, but i could not check in/check out intersystems code.
Not sure how to make the classes writable in TF.exe's configured workspace.
