This Skill allows users to execute C# code in a file-based environment without the need to create a full project, making it ideal for experimentation, prototyping, and quick scripts.

Core Features & Use Cases

  • File-Based Execution: Run C# code in a simple file without a project.
  • Single-File Apps: Support for small C# applications with a single entry point file.
  • Multi-File Apps: Ability to include additional files with #:include directive.
  • Use Case: A developer can quickly test a C# concept or prototype a feature without the overhead of setting up a full project.

Quick Start

Run a simple 'Hello World' C# program with:

dotnet hello.cs

Frequently Asked Questions about csharp-scripts

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run a C# script without creating a project?▼

You can run C# code without a project by executing a single .cs file directly in a file-based environment. This approach allows you to quickly test concepts and prototype features without the overhead of setting up a full .NET solution.

Does file-based C# execution support multi-file applications?▼

Yes, file-based C# execution supports multi-file applications. You can include additional files in your script by using the `#:include` directive, allowing you to organize larger prototypes across multiple files without needing a project.

What .NET SDK version is required to execute C# scripts directly?▼

Executing C# scripts directly from a file requires .NET SDK 10.0 or later. This environment enables rapid prototyping and testing of language features without the overhead of creating a full project or solution.

Can I use this approach for rapid prototyping and testing C# language features?▼

Yes, running C# code in a file-based environment is specifically suitable for rapid prototyping and testing language features. It eliminates the need for a full project, making it ideal for experimentation and small utility applications.

What is the best way to prototype a small C# utility without project overhead?▼

The best way to prototype a small C# utility is to run it as a single-file app. This method provides a simple entry point file for execution, bypassing the overhead of generating a complete .NET project structure.
