Dotnet Csharp Dependency Injection

What it does

This skill enables AI agents to understand and apply Dependency Injection (DI) principles within .NET C# applications. It allows the agent to generate code snippets, explain DI containers, and assist in resolving dependency resolution issues. The skill facilitates creating loosely coupled, testable, and maintainable software architectures using modern .NET practices.

When to use it

• Generating Test Code: When you need assistance writing unit tests for classes that rely on external services or dependencies.
• Refactoring Legacy Code: To help modernize older C# projects by introducing DI patterns.
• Understanding DI Containers: If you're learning about DI containers like Autofac, Ninject, or Microsoft’s built-in container and need explanations or examples.
• Debugging Dependency Resolution Issues: When facing problems with how dependencies are being injected into your application.

Key capabilities

• Generates C# code using Dependency Injection patterns.
• Explains the purpose and benefits of DI.
• Provides examples of common DI containers (Autofac, Ninject, Microsoft DI).
• Assists in resolving dependency resolution errors.

Example prompts

• "Show me how to register an interface and implementation with Autofac."
• "Explain the difference between constructor injection and property injection in C#."
• "Generate a unit test for a class that uses Microsoft's built-in DI container."

Tips & gotchas

• The agent’s effectiveness depends on understanding of .NET concepts. A basic familiarity with C# is recommended.
• Be specific about the DI container you want to use when requesting code examples, as syntax varies between containers.
