As Microsoft announced some new WPF features, I found a good excuse to do a WPF blog post .
Recently I had to do some changes to an WPF application I built some time ago. While implementing the change, I noticed that a new version of Caliburn.Micro was available. I always loved Caliburn.Micro, it is still one of the best MVVM frameworks out there.
Now doing this upgrade wasn’t that hard but wasn’t a walk in the park either. Here are some of the problems I encountered:
- Bootstrapper<T> no longer exists. Instead you have to inherit from BootstrapperBase.
- Inside the Bootstrapper override the OnStartup method and call the DisplayRootViewFor<> method:
protected override void OnStartup(object sender, StartupEventArgs e)
- EventAggregator.Publish now takes an action to marshal the event. You can still use the EventAggregator.PublishOnUIThread if you want the original behaviour.
Message.Attachshould be renamed from
