.net-core Dependency Injection

Question

I have a Generic repository which I want to register for DI, it implements an interface IRepository.

Normally I would create an instance of it like this:

<

You could use a convention based registration library like Scrutor.

Scrutor is a small open source library that provides a fluent API to register services in your Microsoft.Extensions.DependencyInjection container based on conventions (Similar to Autofac's RegisterAssemblyTypes method, StructureMap's Scan method and Ninject's Conventions package).

This will allow you to do something like this:

services.Scan(scan => scan
            .FromAssemblies(<>.GetTypeInfo().Assembly)
                .AddClasses(classes => classes.Where(x => {
                    var allInterfaces = x.GetInterfaces();
                    return 
                        allInterfaces.Any(y => y.GetTypeInfo().IsGenericType && y.GetTypeInfo().GetGenericTypeDefinition() == typeof(IRepository<>)));
                }))
                .AsSelf()
                .WithTransientLifetime()
        );
