services.Configure not working with Configuration

[John0x]

Hey, I'm using the newest unstable coreclr version of dnx (upgraded using dnvm upgrade -u -r coreclr today).

public class Settings
{ 
public string Test {get;set}
}

services.Configure<Settings>(Configuration);

Does not work, even though the official documentations says it should.
services.Configure(Configuration.GetSection("Settings"));
Does not work either, since the Configure method expects an Action

Where is the problem?

Make a full sample, put it on github and we'll have more data about what's not working and why.

Well, it's pretty simple actually.
It's just a standard asp.net webApi project which I've modified to work with rc2.

project.json:
https://gist.github.com/John0x/318f2603321d8bc56a99

Main class:
https://gist.github.com/John0x/2646d038d483fd563497

Gives the error:
DNX Core 5.0 error CS1503: Argument 2: cannot convert from 'Microsoft.Extensions.Configuration.IConfigurationRoot' to 'System.Action<CustomSettings>'

You are just missing the reference to the Microsoft.Extensions.Options.ConfigurationExtensions which contains this method.

Even after adding a reference, still getting same error.

i got it working, when changed this "services.Configure(Configuration.GetSection("Settings"));"
to
services.Configure(options => Configuration.GetSection("Settings"));

A bit late to the party here but it might help someone, I'm upgrading an MVC 5 application to use DI but I was struggling to get strongly bound AppSettings/ConnectionStrings working;

In .NET Core (as of 2.1.5) I would simply write the below;

services.Configure<AppConfig>(Configuration.GetSection("AppConfig"));
services.Configure<ConnectionStrings>(Configuration.GetSection("ConnectionStrings"));

I tried the above example and it certainly compiles, but doesn't actually bind the properties - at least using newest packages;

services.AddOptions();
services.Configure<AppConfig>(options => Configuration.GetSection("AppConfig"));
services.Configure<ConnectionStrings>(options => Configuration.GetSection("ConnectionStrings"));

The version which actually bound the values was;

services.AddOptions();
services.Configure<AppConfig>(x => Configuration.GetSection("AppConfig").Bind(x));
services.Configure<ConnectionStrings>(x => Configuration.GetSection("ConnectionStrings").Bind(x));

Maybe that helps the next person to come along here...
