Prism - Upgrading Prism 2 to Prism 4 RRS feed

  • Question

  • We´ve upgraded our Silverlight 5 application to Prims 4.

    We have taken the following steps:

    1. Remove all references to Microsoft.Practices.Composite(Microsoft.Practices.Composite, Microsoft.Practices.Composite.Presentation, Microsoft.Practices.Composite.UnityExtensions)

    2. Replaced the references above with (Microsoft.Practices.Prism, Microsoft.Practices.Prism.Interactivity)

    For some reason the Silverlight project that host the solution requires a refernce to Microsoft.Practices.Unity.Silverlight. After adding this, the solution builds.

    When we run the application we get the following error message:

    "The current type, Microsoft.Practices.Prism.Regions.IRegionBehaviorFactory, is an interface and cannot be constructed. Are you missing a type mapping?"

    We never actually changed the code that handles the bootstrapping. Is there a change in the implementation between Prism2/composite and Prism 4?

    Regards/C

  • Give a try to add the reference of the following also -

    • Microsoft.Practices.Prism.UnityExtensions
    • Microsoft.Practices.ServiceLocation

    Also, You will have to chage the Namespace Microsoft.Practices.Prism.* throught your application.

  • Thnx! Eventually, it worked out fine. We had to change a lot of references, but the only bit of code we had to change was the following:

    protected override IModuleCatalog GetModuleCatalog => protected override IModuleCatalog CreateModuleCatalog

    Thank you, for your input! Regards /C
