问题
I want to migrate a project written with Prism 4 into Prism 6.
In Prism 4 the CompositePresentationEvent<T> type is under Microsoft.Practices.Composite.Presentation.Events namespace.
But when I pulled Prism 6 from nugget and removed old Prism 4 references, I could not see this event type anywhere in Prism 6 namespaces.
Anyone can help me a bit?
回答1:
The CompositePresentationEvent has been removed in Prism 6. If I recall correctly, if was deprecated in Prism 5, and removed completely in Prism 6.
Now, you need to use the PubSubEvent<TPayload> in the Prism.Events namespace.

What R. Richards wrote is correct and has thus been correctly marked as an answer. Might I however offer you the following link as a reference:
Upgrading from Prism Library 4.1
As the title suggests it refers to upgrading from version 4.1 to 5.0 but there are, apart from the change mentioned here, other changes noted there which you might find helpful.
