RemoteCommandLine Execution Idea to make smarter

[danielmarbach]

Found a todo in the remote command line executor which indicates that currently all remote tasks are hard coded. A simple idea to make the console smarter would be the following:

public interface IRemoteTaskCreator
{
    Task Create(PhysicalServer server, string[] args);
}

[InvokedWith("create_queue")]
public class CreateLocalMsmqQueueTaskCreator : IRemoteTaskCreator
{
    public Task Create(PhysicalServer server, string[] args)
    {
        var queuename = args[1];
        var queueAddress = new QueueAddress(queuename);
        var transactional = false;
        if (args.Length > 2)
        {
            bool.TryParse(args[2], out transactional);
        }

        var task = new CreateLocalMsmqQueueTask(server, queueAddress, transactional);

        return task;
    }
}

public class InvokedWithAttribute : Attribute
{
    public string InvokeCommand { get; private set; }

    public InvokedWithAttribute(string invokeCommand)
    {
        InvokeCommand = invokeCommand;
    }
}

A simple reflection mechanism could cache all inheritors of IRemoteTaskCreator in a dictionary with <InvokeCommand , IRemoteTaskCreator>. The remote console then simple does:

var result = new DeploymentResult();
var creator = ClassWhichHasReflectionMagic.CreateRemoteTaskCreator(args[0]);
var task = creator.Create(_server, argsWithoutFirstEntry);
result = task.Execute();
return result;

Simple. Easy. Extendable.
