using Docker.DotNet;

public class DockerImagePuller
{
    private DockerClient _dockerClient;

    public DockerImagePuller()
    {
        _dockerClient = new DockerClientConfiguration().CreateClient();
    }

    public async Task PullImage(string imageName)
    {
        await _dockerClient.Images.CreateImageAsync(
            new ImagesCreateParameters
            {
                FromImage = imageName
            },
            null,
            new Progress<JSONMessage>());
    }
}

public class Program
{
    public static async Task Main(string[] args)
    {
        DockerImagePuller imagePuller = new DockerImagePuller();
        await imagePuller.PullImage("nginx:latest");
    }
}
