You can run C# code without a .csproj file by using the dotnet CLI to execute single files directly. This leverages the .NET SDK file-based application feature to skip traditional project structure overhead for simple scripts.

Yes, you can add NuGet packages to a C# file-based app by using embedded `#:` directives within the script. This allows you to configure packages, SDKs, and properties directly in the code file without a project file.

The best way to prototype small C# utilities is using file-based apps, enabling rapid execution of single C# files via the dotnet CLI without explicit project files, ideal for automating repetitive tasks quickly.

Yes, the dotnet CLI supports building and publishing single C# files. The .NET SDK file-based application feature facilitates script execution, building, and publishing directly from the file using embedded `#:` directives for configuration.

You should avoid using file-based C# apps for complex applications requiring extensive project configurations, as this approach is designed for utilities, small tools, and rapid prototyping without explicit project files.
