Get Multiple Connection Strings in appsettings.json without EF

Question

Just starting playing with the .Net Core RC2 by migrating a current MVC .Net app I developed. It looks like to me because of the way that configuration is handled with apps

Answer 1

There are a couple of corrections that I made to Adem's response to work with RC2, so I figured I better post them.

I configured the appsettings.json and created a class like Adem's

{
    "ConnectionStrings": {
      "DefaultConnectionString": "Default",
      "CustomConnectionString": "Custom"
    }
}

and

public class ConnectionStrings
{
    public string DefaultConnectionString { get; set; }

    public string CustomConnectionString { get; set; }
}

most of Adem's code comes out of the box in VS for RC2, so I just added the line below to the ConfigureServices method

services.Configure(Configuration.GetSection("ConnectionStrings"));

The main missing point is that the connection string has to be passed to the controller (Once you’ve specified a strongly-typed configuration object and added it to the services collection, you can request it from any Controller or Action method by requesting an instance of IOptions, https://docs.asp.net/en/latest/mvc/controllers/dependency-injection.html)

So this goes to the controller,

private readonly ConnectionStrings _connectionStrings;
        public HomeController(IOptions connectionStrings)
        {
            _connectionStrings = connectionStrings.Value;
        }

and then when you instantiate the DAL you pass the appropriate connectionString

DAL.DataMethods dm = new DAL.DataMethods(_connectionStrings.CustomConnectionString);

All the examples show this, they just don't state it, why my attempts to pull directly from the DAL didn't work
