Is it possible to install VS Code extensions in Visual Studio or vice versa?

I have Visual Studio installed, but not Visual Studio Code.

There are extensions available in the Visual Studio Code Marketplace, but not available in the Visual Studio Marketplace, that I would nonetheless love to use in Visual Studio.

Is this possible? Or are the two offerings just fundamentally different? Hacky solutions welcome.

Example: I want Rainbow-CSV. Double-clicking the VSIX just tells me to try it in VS Code:

Do people often run VS and VS Code side by side? There are far more open source offerings for VS Code versus VS.

I think no. VS Code and Visual Studio are not the same, and that includes the ways their extensions work not being the same-

• the way they are run: (VS Code uses JavaScript (interpreted language), and I think Visual Studio uses C++/C#(?) (C# has a intermediate language compiler and a JIT compiler- I'm not sure which is used for Visual Studio extensions. C++ is a compiled language))

• the extension and editor system they are hooking into: compare Visual Studio's with VS Code's (they are vastly different).

Though that's not to say that some extensions made for both editors for similar purposes might not use the same underlying software components, as I think is the case with cpptools.
