What happened to the MEF type, "AttributedAssemblyPartCatalog"?

Question

Many simple MEF examples (listed below) use AttributedAssemblyPartCatalog .

• In-app MEF hosting on the CodePlex MEF page
  
• A simple introduction to extensible applications with Managed Extensions Framework by Brad Adams
  
• Managed Extensibility Tutorial - MEF by David Hayden
  

I downloaded the MEF source from CodePlex , but still can not find this type anywhere.

What happened to the AttributedAssemblyPartCatalog and what is an alternative way to create a recognizer?

Answer 1

They renamed it (along with other directories) to a shorter identifier in drop 4 (now we need to reset 5). Now it is called AssemblyCatalog. Similarly, DirectoryPartCatalog got renamed to DirectoryCatalog.
