Use of Task.Factory.StartNew in PublishOnBackgroundThread() method

[zachjacobs]

This is more of a question than anything. We have noticed occasions where our message handlers would be executing on the UI thread even though we always post messages using the PublishOnBackgroundThread method to publish these messages. Upon reading into the issue and looking at the Caliburn.Micro source, I suspect this might be due to the usage of Task.Factory.StartNew in the PublishOnBackgroundThread method. Would Task.Run be more appropriate here to ensure that we are always using TaskScheduler.Default?

As we support Silverlight 5 and .NET 4.0 Task.Run is not an option.
If I remember correctly it is only a wrapper around Task.Factory.StartNew, so it should be enough to set the right parameters. Suggestions?

My apologies on not following up with your question. I was on vacation last week. Your fix is exactly what I would have suggested. Thanks!
