Upgrading to Caliburn.Micro 2.0

As Microsoft announced some new WPF features, I found a good excuse to do a WPF blog post Glimlach.

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)
{ 
          DisplayRootViewFor<IShell>(); 
}

  • EventAggregator.Publish now takes an action to marshal the event. You can still use the EventAggregator.PublishOnUIThread if you want the original behaviour.
  • Message.Attach should be renamed from clr-namespace:Caliburn.Micro;assembly=Caliburn.Micro to clr-namespace:Caliburn.Micro;assembly=Caliburn.Micro.Platfor

Some other breaking changes can be found here: http://caliburnmicro.com/documentation/migrating-to-2.0.0

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
