Is this a suitable event approach for a Windows service?

Question

I read event oriented design. I am having problems when I am on my head. I am considering using this for a Windows service that monitors, analyzes, and processes information coming from a third-party TCP stream. Is the following approach worthy, or am I missing something?

My plan is for the main service to be just a container for events:

public class MyService
{                      

    public void RegisterAgent(ServiceAgent agent)
    {
        Log("Initializing agent " + agent);
        agent.Initialize(this);
        Log("Done intializing agent " + agent);
    }

    public void Log(string messageText)
    {
        OnSimpleLogEventLogged(this, new SimpleLogEventArgs(messageText));
    }

    protected void Raise<T>(EventHandler<T> eventHandler, object sender, T args) where T : EventArgs
    {
        var handler = eventHandler;
        if (handler == null) return;                       
        handler(sender, args);

    }

    public event EventHandler<SimpleLogEventArgs> SimpleLogEventLogged;
    protected void OnSimpleLogEventLogged(object sender, SimpleLogEventArgs args)
    {
        Raise(SimpleLogEventLogged, sender, args);
    }

    public event EventHandler<TextRecievedEventArgs > TextRecieved;
    public void OnTextRecieved(object sender, TextRecievedEventArgs args)
    {
        Raise(TextRecieved, sender, args);            
    }

    public event EventHandler<TextParsedEventArgs> TextParsed;
    public void OnTextParsed(object sender, TextParsedEventArgs args)
    {
        Raise(TextParsed, sender, args);            
    }

    ...
}

Then, using MEF or the like, I will register instances of "ServiceAgent" that simply handle and / or generate events, not necessarily doing so in the background thread. For instance:

public class TextParsingAgent : ServiceAgent
{

    public override void Initialize(MyService service)
    {
        service.TextRecieved += TextRecieved;
        base.Initialize(service);
    }

    void TextRecieved(object sender, TextRecievedEventArgs e)
    {
        ThreadPool.QueueUserWorkItem(TextRecievedAsync, e);
    }

    private void TextRecieved(object state)
    {
        var e = (TextRecievedEventArgs)state;
        //TODO:Parse text into something meaningful and store in textParseEventArgs
        service.OnTextParsed(textParseEventArgs);
    }
}

Raise() , -, :

public event EventHandler<TextParsedEventArgs> TextParsed = (sender, e) => { };

TextParsed(...) , .
