How to add a generic dependency injection [duplicate]

Answer 1

Since this question is still not properly marked as duplicate: The way to register a Generic class:

services.AddScoped(typeof(IRepository<,>), typeof(Repository<,>));

now you can resolve it in the following way:

serviceProvider.GetService(typeof(IRepository<A,B>));
// or: with extensionmethod
serviceProvider.GetService<IRepository<A,B>>();
