As I said, I am a new user dedicated server user. Please can you tell me what should I do to install Visual studio and others software on my dedicated server?
Hey there! Since these aren't tools that come with the cPanel product, it would be best to consult each individual installation guide to see if they are compatible with your server:
Visual Studio Code is free and available on your favorite platform - Linux, macOS, and Windows. Download Visual Studio Code to experience a redefined code editor, optimized for building and debugging modern web and cloud applications.
The Eclipse Foundation - home to a global community, the Eclipse IDE, Jakarta EE and over 415 open source projects, including runtimes, tools and frameworks.
www.eclipse.org
You would also need root access to install these tools, so you would not be able to do that if you only have cPanel access to the server.
