What is included in MEF 2?

Question

I see work is still going on with new features on MEF (MEF Codeplex site) and they are shipping MEF 2 beta releases, however they do not have any decent documentation on what the new features are experimenting/exploring/building?

So, what are the new features (in a little bit of detail please, a sentance or two for each would be great) that are part of MEF 2?

Answer 1

I know one big feature is support for open generics. This allows us to import parts that look like this:

IRepository<T>
{

}

using an import that looks like this

[Import(typeof(IRepository<>))]
private IRepository<Users> userRepository;

Answer 2

From the preview documentation

• Support for generic types.
• Convention-based programming model that enables you to create parts based on naming conventions rather than attributes.
• Multiple scopes.
