[dba-VB] VS2010: Dependency Injection (DI), The Microsoft Extensibility Framework (MEF)

Hi Gustav --

I'd go for it at least for educational purposes.
But using DI in business apps we develop could be often an overkill AFAIS
now (I can be wrong) - using DI always(?) needs more time to develop and
test - yes, it should pay back well in long run but how often do we have
that "long run" coming into reality?

Here is a link on foundation info:
http://martinfowler.com/articles/injection.html

Trying to be more "ground based" here these days :)

Thank you.

P.S. I suppose it would be a lot of fun to (re-)develop large business apps
using DI and MEF - are there anybody who have funds for such a project? -
ready to go with that here :)

Hi all

<quote>
Dependency Injection (DI) is a technique that includes a set of well-known
design patterns, and most existing DI Containers operate within the
boundaries of these patterns. The Microsoft Extensibility Framework (MEF) -
which is a part of .NET 4.0 - has many similarities with DI Containers,
although there are differences. This session dives into the relationship
between MEF and the existing DI patterns to better understand what MEF is -
and is not.

Could someone please indicate what this is about and/or provide a link to
some tutorial on the subject?
Should I attend this 2½ hour session at my local user group?
