Managed Extensibility Framework released on CodePlex

I am super jazzed that we released the Managed Extensibility Framework CTP2 on CodePlex. 

http://www.codeplex.com/MEF blocks.png

 

We have taken a lot of good feedback in from the community... a few cool things here:

 

1. We shipped source code!

2. We have a complete set of developer Overviews,  guidelines and samples.

3. Because of community feedback, we now support constructor injection

4. MEF itself is now more extensible... For example, want POCO?, no problem, it is now possible to write an extension to store the customer attribute metadata in an external file.    More to come here, but it is a solid start!

5. Lots of API cleanup based on feedback..

 

Related, we also recently updated  Framework Design Studio to use MEF, so there is an example of using MEF is a real app.  Thanks to Nick Moloney, our excellent high school summer intern for doing this work!

 

We'd love to hear your feedback and comments!

Thanks!  Fixed, that is what I get for posting at night.

Sorry if this has been answered elsewhere. What is the difference between MEF and Unity from P&P group?

# Johannes Hansen said on September 6, 2008 10:54 PM:

Isn't it >>Managed<< Extensibility Framework, not >>Microsoft<< Extensibility Framework? Is MEF a Microsoft project? The posts from you and Glenn Block indicate that it is, so whats the deal.

PS: I raised this question in the MEF discussion forums as well.

This blog was linked to from www.asp.net, what does the extensibility framework have to do with ASP.Net?

# BradA said on September 8, 2008 1:03 AM:

Extensibility with ASP.NET apps is very cool.. You can do a composite UI scenarios, you can select different services to use for the application, switching between product and test DALs..  Look for more samples with ASP.NET soon.

Brad, I'm putting in a vote for "Extensibility with ASP.NET apps".  I think that's an interesting space.  Let us know when you have some samples available.  Thank you.
