You probably want to use the content service Published event, as that executes once the content has finished being published.

You can access all the Umbraco services via the ApplicationContext singleton in Umbraco.Core eg.

ApplicationContext.Current.Services.ContentService;

Example:

public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
{
    ContentService.Published += ContentService_Published;
}

private void ContentService_Published(IPublishingStrategy service, PublishEventArgs<IContent> e)
{
    var contentService = ApplicationContext.Current.Services.ContentService;
    int parentPageToCopyToId = 12345;

    foreach (var doc in e.PublishedEntities)
    {
        contentService.Copy(doc, parentPageToCopyToId, true);
    }
}

I was thinking it would be available then, but the issue is I dont want to run this on every publish, only on the first publish.

In publishing I could look at the has Identity field but after publish it has that, Is there a way to perhaps confirm that its the first version or something with your solution in mind?

That's a good point, but the Publishing event would run every time, too. You probably want to use the ContentService.Created event, in that case, which runs only once when the content is first created.

private void ContentService_Created(IContentService service, NewEventArgs<IContent> e)
{
    var doc = e.Entity;
}

So it seems I have access during the publishing event, but running the content service query seems like a very time consuming thing to run.

Is there a way to access TypedContent in this context?

I would only be looking for already published modules so in theory I could just use the cached data instead of going to the DB for all the content.

You can't access published content until the content is actually published - so it won't be available in the Publishing event, which runs before, only the Published event.

There is a way to access TypedContent, but as I say, it won't exist until published. You'd do something like:

UmbracoHelper umbHelper = new UmbracoHelper(UmbracoContext.Current);

IPublishedContent published = umbHelper.TypedContent(yourContent.Id);

So what I did was I passed the helper through into the event handler and then accessed typed content with that.

So now it's all sorted :)
