New Post: Prism-WPF equivalent to Silverlight's: CompositionInitializer class and SatisfyImports()

Hi,

Based on my understanding the view model can be instantiated in XAML as the view’s DataContext only if a view model does not have any constructor arguments. And as far as I know creating objects defined inXAML by partnering with an Inverse of Control Container is currently not supported.

Regarding the CompositionInitializer class, as far as I know there is no equivalent class forWPF, on the other hand regarding this topic, I believe you could find the following blog post interesting:

• MEF CompositionInitializer for WPF

Also, I believe an alternative for this could be registering the CompositionContainerclass like mentioned in this thread:

• Registering new types with MEF container from ViewModel

As this could let you retrieve this class for example in your view model's constructor, in order to call theSatisfyImportsOnce method to satisfy the Imports defined in the passed class:

this.compositionContainer =ServiceLocator.Current.GetInstance<CompositionContainer>();this.compositionContainer.SatisfyImportsOnce(this);
