You can run a single C# file directly using the `dotnet run hello.cs` command, bypassing the need for traditional `.csproj` project files. This approach simplifies building small .NET applications, scripts, and utilities by compiling and executing the code from one file.

Yes, you can manage NuGet packages in a C# script without a project file by using `#:` directives directly within the single `.cs` source file. This allows you to include package references, project references, and build properties seamlessly.

Yes, .NET single-file execution supports Native AOT compilation, compiling scripts into optimized, self-contained executables by default. This feature enables efficient script and utility development without the overhead of a traditional project setup.

The best way to build a quick command-line utility in C# is using single-file development to write, compile, and run code from one `.cs` file. This eliminates the overhead of setting up a full Visual Studio project for automating repetitive tasks.

No, you do not need Visual Studio to automate tasks with a C# script. You can write a single `.cs` file with standard C# code and execute it directly using the .NET CLI, avoiding the overhead of a full project setup.

Building .NET apps from single C# files is designed for small applications, scripts, and utilities, and may not suit large-scale enterprise architectures. It uses `#:` directives for package management and Native AOT compilation, focusing on lightweight script development rather than complex project structures.
