ModuleNeedsRetrieval(ModuleInfo)

Checks if the module needs to be retrieved before it's initialized.

Declaration
protected override bool ModuleNeedsRetrieval(ModuleInfo moduleInfo)
Parameters
Type Name Description

OnImportsSatisfied()

Called when a part's imports have been satisfied and it is safe to use.

Declaration
public virtual void OnImportsSatisfied()
Remarks

Whenever the MEF container loads new types that cause ImportedModules to be recomposed, this is called. This method ensures that as the MEF container discovered new modules, the ModuleCatalog is updated.
