How Can I Register and Manage Services in a Large C# Project?

currently there is no automatic registration. each service must be registered via an api call. you could define an interface used to register a component. each component that wants to be registered could implement this interface. at startup use reflection to find all classes with the interface then call the interface for each class.

Hi Fatih,
Use constructor infusion for administrations, bunch them into modules, and influence Scrutor for programmed enrollment. Oversee administration lifetimes cautiously, and consider Lazy<T> for asset weighty administrations. This guarantees adaptable and proficient help the board.

@fatih uyanık , Welcome to Microsoft Q&A, sorry for late response, you could look at the following answers for your questions:

Do I need to create a combined service to manage this?

Yes, you could create a combined service manage them. It can simplify the management of multiple services. This pattern allows you to encapsulate calls to multiple services behind a single interface, reducing clutter in your ViewModels.

Then, do I need to register all these services in the container?

You could register both the individual services and the combined service in your dependency injection container. The combined service can then be injected into your ViewModels.

Also, some of these services are long-lived, and some need to be created on demand. What is the solution to this?

You need use the appropriate service registration methods for different situations:

1. Transient: Use for lightweight, stateless services.
2. Scoped: This is less common in WPF but can be used in specific scenarios if you create a scope manually.
3. Singleton: Use for services that maintain state or are expensive to create (like a configuration manager).
4. If a service needs to be created on demand, consider using a factory pattern. This allows you to create instances of services only when needed.

Finally, I read in some sources that they should be registered in ViewModels. This caused me confusion.

Inject the composite service (or individual services, depending on your design) into your ViewModels. This approach keeps your ViewModels focused and avoids the clutter of too many services.

Hope it could help you.

Jack
