Your comment says “Microsoft Studio Code” and “MS Code”, neither of which is a thing (as I tried to point out). The actual software you’re talking about is “(MS) Visual Studio” and “(MS) Visual Studio Code”, and that naming convention is pretty common for products (and other things) that are different but similar (think Photoshop and Photoshop Express, PSX and PS2, C and C++ etc.).

Are you talking about Visual Studio Community/Professional/Enterprise and Visual Studio Code? Because if so, I don’t really agree. Visual Studio is an IDE (VS Community is the free tier) whereas VS Code is a code editor (as the name implies).
