File-Based C# Apps

When to Use

• Testing a C# concept, API, or language feature with a quick file-based app
• Prototyping logic before integrating it into a larger project
• Building a small utility from one entry-point file and a few helper .cs files

When Not to Use

• The user asks for a language-agnostic quick script, throwaway computation, or shell/Python/PowerShell-style automation
• The user needs a full project, solution integration, or project references in an existing app
• The user is working inside an existing .NET solution and wants to add code there
• The app is large enough that project structure, build customization, tests, or publish configuration should live in a .csproj
