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?

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.

    Love the first line of code as this allowed me to register the service for all descendants of "Person" (in this case) !!! Awesome! – neggenbe Mar 29 '20 at 11:05

Have you tried

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

  • That won't compile. You have to use run-time `System.Type` instances via `typeof()` when referencing open generics. – Technetium Aug 29 '16 at 17:10
