What is the primary distinction between Visual Studio and Visual Studio Code?
- Visual Studio is a full-featured IDE, while Visual Studio Code is a lightweight code editor.
- Visual Studio is open-source, while Visual Studio Code is proprietary.
- Visual Studio is cross-platform, while Visual Studio Code is Windows-only.
- Visual Studio supports Python, while Visual Studio Code does not.
The primary distinction between Visual Studio and Visual Studio Code is that Visual Studio is a full-featured Integrated Development Environment (IDE) with extensive features for various languages and platforms, while Visual Studio Code is a lightweight, open-source code editor.

Imagine you're working on a large project with multiple feature folders, and each folder has its own _ViewImports.cshtml. You notice a certain namespace is not being recognized in one of the Razor views. What could be the most likely reason for this?
- The _ViewImports.cshtml file is missing from the specific feature folder.
- There's a typo in the namespace declaration in _ViewImports.cshtml.
- Razor views don't support custom namespaces.
- The project doesn't include the required NuGet package for the namespace.
The most likely reason for the unrecognized namespace is a typo in the namespace declaration in the _ViewImports.cshtml file. Razor views use these files to import namespaces, and a typo can cause issues with namespace recognition. It's important to double-check the spelling and correctness of the namespace declaration in such cases.
