namespace WorkflowActions
{
	using System;

	internal class Program

			var workflowService = new WorkflowService();
			var workflow = workflowService.Get(workflowName);
			workflow?.Run();
		}
	}

	public interface IRunnableWorkflow
	{
		void Run();
	}

	public interface IWorkflowService
	{

	public class Ftp : IRunnableWorkflow
	{
		public void Run()
		{
			Console.WriteLine("************************************************Inside FTP");
			Console.ReadKey();
		}
	}

	public class WorkflowService : IWorkflowService
	{
		public IRunnableWorkflow Get(string name)
		{
			var currentNameSpace = typeof (Program).Namespace;

			var type = Type.GetType(currentNameSpace + "." + name);
			if (type == null)
				return null;

			return (IRunnableWorkflow) Activator.CreateInstance(type);
