What are some common mistakes in C# dependency injection?

Some common mistakes include not using interfaces, overusing singletons, and failing to manage lifetimes properly.

Can you explain why using singletons can be a mistake?

Using singletons can lead to hidden dependencies and make unit testing difficult, as they introduce global state.

What should I use instead of singletons?

Consider using scoped or transient lifetimes for your services, which can help manage dependencies more effectively.

How can I avoid these mistakes in my code?

You can follow best practices like using interfaces, keeping your services stateless, and regularly reviewing your DI setup.
