Dependency Injection¶

Introduction¶

Explain how CoreSystem integrates with the .NET dependency injection container.

Registration Pattern¶

Describe the standard registration pattern used by all CoreSystem packages.

Example:

• AddCoreResilience()
• AddCoreHttp()
• AddCoreRateLimiting()
• AddCoreMemory()
• AddCoreRedis()

Configuration Pattern¶

Explain how each package uses the Options pattern.

Example:

builder.Services.AddCoreResilience(options => { ... });

Service Lifetimes¶

Describe when CoreSystem uses:

• Singleton
• Scoped
• Transient

and the reasoning behind each choice.

Extension Methods¶

Explain why every package exposes extension methods for IServiceCollection.

Package Dependencies¶

Describe how packages depend on each other.

Best Practices¶

• Register packages once.
• Configure through Options.
• Avoid manual registrations.
• Prefer the provided extension methods.

Common Errors¶

• Missing service registrations
• Invalid options
• Duplicate registrations
• Missing provider packages
