Register Dependencies in ASP.NET Core app
Since asp.net is new and its bit of a learning curve, where and how you do certain things. I used Unity, TinyIoC, Ninject in the past. But ASP.NET Core includes a simple built-in container.
in your Startup.cs file, find the section called ConfigureServices(IServiceCollection services)
public void RegisterRepositoryDependencies(IServiceCollection services)
Now your Controllers you can use the dependencies.
