I have an error calling one of the methods of the configuration items :

IConfiguration' does not contain a definition for 'GetOptions' and no accessible extension method 'GetOptions' accepting a first argument of type 'IConfiguration' could be found (are you missing a using directive or an assembly reference?

This is the part where the error is showing :

<pre>using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;     
public static class Extensions
    {
        private static bool _initialized;
        ....
        ....
        private static JaegerOptions GetJaegerOptions(IServiceCollection services)
        {
            using (var serviceProvider = services.BuildServiceProvider())
            {
                var configuration = serviceProvider.GetService<IConfiguration>();
                services.Configure<JaegerOptions>(configuration.GetSection("jaeger"));
                return configuration.GetOptions<JaegerOptions>("jaeger");
            }
        }
        }
    }

and the related class JaegerOptions.cs :

public class JaegerOptions
{
    public bool Enabled { get; set; }
    public string ServiceName { get; set; }
    public string UdpHost { get; set; }
    public int UdpPort { get; set; }
    public int MaxPacketSize { get; set; }
    public string Sampler { get; set; }
    public double MaxTracesPerSecond { get; set; } = 5;
    public double SamplingRate { get; set; } = 0.2;
}

My project looks like this :

What I have tried:

I have already installed Microsoft.Extensions.Configuration.Binder but I am still getting same error. Both Microsoft.Extensions.Configuration and Microsoft.Extensions.Configuration.Binder are installed.
