Comparison to Caliburn.Micro

Although Stylet is based on, and inspired by, Caliburn.Micro, it does have quite a lot of differences. These are summarised below.

• Stylet requires .NET 4.5, and has dropped support for Windows Phone and Silverlight. The View-First approach has also been dropped. This leads to a significant reduction in complexity.
• Conventions have been largely removed. Binding is done explicitly.
• ActionMessages have been replaced with Actions. This has removed the dependency on System.Windows.Interactivity, and is overall a more powerful and intuitive approach.
• IGuardClose.CanClose has been rewritten to return a Task, instead of accepting a callback (and has been renamed to CanCloseAsync).
• The ViewModelBinder and ViewModelLocator static classes have been collapsed into a single non-static ViewManager.
• IDeactivate has been split into IDeactivate and IClose.
• A powerful IoC container (StyletIoC) is provided and configured by default.
• A Window's lifecycle is now affected when it's minimized / restored.
• Stylet allows you to specify how to dispatch PropertyChanged events.
• Stylet introduces Conductor<T>.Collections.Navigation.
• Stylet includes a MessageBox implementation.
• Stylet adds ValidatingModelBase, which derives from PropertyChangedBase and is subclassed by Screen. This allows easy validation of ViewModels using the validation library of your choice.
• Unfortunately, Caliburn.Micro is no longer actively maintained (see the announcement published on 18 Jun 2020).
