How to register generic service [duplicate]

• vNext Dependency Injection Generic Interface 1 answer

I am planning to move my system to generic service layer.

public interface IAbcService<TEntity> where TEntity : class

public class AbcService<TEntity> : IAbcService<TEntity> where TEntity : class

I tried something but it does not work.

services.AddTransient<typeof(IAbcService<MyEntity>), AbcService();
....
....
....

I'm using some of my entities and along with that I am trying to add it to properties.

How can I register a generic service in asp.net core?

Answer 1

Have you tried

services.AddTransient<IAbcService<>, AbcService>()

Answer 2

I wanted to try the exact same thing before and I've got it to work like this:

services.AddTransient(typeof(IAbcService<>), typeof(AbcService<>));
services.AddTransient(typeof(IAbcService<Person>), typeof(AbcService<Person>));

Do mind the different structure, this is registering by parameters in a method.

To elaborate, as you can see in the example above, with the new DNX framework package we now can register both open and closed generics. Try it out, both lines will work.
