How to make the connection string available in a N-Tier ASP.NET MVC Core 1.0 App with Autofac

Question

I wired the layer together via autofac modules. Big thanks to endeffects. Here is the HowTo. Now I'm trying to make the connection string available in the DAL layer. I tried to register the:

Configuration (Microsoft.Extensions.Configuration)

From the Startup class but without any success.

Answer 1

I have the following line in my ConfigureServices method in startup.cs:

services.AddSingleton(serviceType => Configuration);
services.AddInstance<Microsoft.Extensions.Configuration.IConfiguration>(Configuration);

builder.Populate(services);
var container = builder.Build();
var serviceProvider = container.Resolve<IServiceProvider>();
return serviceProvider;

Then in my DAL, I access that via constructor injections like:

public MyDataContext(IConfiguration configurations)

I can then access that item and pull my connection info like:

configurations["Data:MyConnection:ConnectionString"]
