New Post: Prism-MEF Splash screen Module

Hi,

We took the sample you provided and made changes to it in order to be able to use MEF, some of which include the following:

• Migrated application from Prism 2.0 to Prism 4.1
• Changed Bootstrapper to aggregate modules using MEF
• Added ModuleExport, Export and ImportingConstructor attributes to the corresponding types
• Removed the manual module initialization from the Bootstrapper (the initialization should be done automatically by the ModuleCatalog)
• Made modules dependent of the Splash Module, to avoid having them being initialized before it
• Events that were published on the Bootstrapper were moved to their corresponding Modules
  

Also we found the following issues that we changed to follow the best practices:

• Registering types against themselves like this: Container.RegisterType<SplashViewModel, SplashViewModel>();
• Manual initialization of modules in Bootstrapper. Modules should have an Initialize method.
  

You can find the sample below:

Hope this helps,
