Dependency Injection Killed by Simon Ince

Posted 18 days ago by nor...@blogger.com (Gael Fraiteur)

Dependency Injection is Dead! is the somewhat provocative title of an interesting post of Simon Ince.

Simon indeed proposes another approach: AOP-powered Dependency Resolution. The idea is to use aspects on fields or properties to resolve ... [More] the dependencies on-demand, when the property or field value is retrieved. Technically, it would be enough to turn the old good [Dependency] custom attribute into an aspect.

I won't copy-paste Simon's stuff, so please read from the horse's feather on his blog.

A refreshing view on a topic that tends to become sanctified and therefore unchallenged in our community.

Even if this approach does not solve all the use cases of Dependency Injection, covers a lot of them in quite an elegant way. While it would be theoretically easy to use this approach with dependency injection frameworks (because dependency resolution is obviously one the major components of a DI framework, the other big one being the object builder), I noticed that Unity does not offer the functionality at the required level of granularity. A pity, which I have notified in illo tempore to the Unity team. Maybe some day wind will turn...

Happy PostSharping!

Introducing PostSharp VIP Content

Posted 19 days ago by nor...@blogger.com (Gael Fraiteur)

I have opened a special section of the forum for VIP community members. The objective is to share content with DNUG leaders, speakers, and technical writers.

Indeed, I've long looked for a way to make it easier for speakers to get something ... [More] to show about PostSharp: some figures, some slides, or even whole presentations ready to be served. However, I needed some way to ensure that the same content will not be served twice to the same audience, and they the audience does not just get the same content as it can download from the web site.

The solution I found: make this content available to selected people only.

So if you are a user group team leader, conference organizer, speaker, technical writer -- or if you have any other good reason to get access to this content -- you can request membership in the VIP group. The VIP section is implemented as a protected forum in our message board, where downloads are simply attachments to the topic. Every time the content will be delivered somewhere, I'll add a post to the topic.

By the way, even if you get access to this section, you still need to respect copyrights and request for permission before publishing any non-trivial part of the content.

I just hope I don't frustrate tons of people because of that... Oh, if you want to see the content, why not ask your UG leader to organize something?

Happy PostSharping,

PostSharp Present At SDN Event June 2008, Ede, The Netherlands

Posted about 1 month ago by nor...@blogger.com (Gael Fraiteur)

I will present aspect-oriented programming and PostSharp at the
Software Development
Event (SDE) in Ede, The Netherlands, on June 23th, 2008.

I have two sessions of 75 minutes each:

Addressing non-functional
requirements ... [More] with aspects: a general
introduction to aspect-oriented programming
(AOP) with a presentation of typical problems
of software engineering that can be better
solved using AOP and an outlook at different
popular AOP solutions.
Towards more complex aspects using
PostSharp: a thorough trip into
PostSharp Laos showing how to concretely
develop more complex aspects and apply them to
business applications.

Although my talks have been placed into the
Visual Basic track, it is actually not specific to
VB at all, and all samples will even be in C#.

I will be there till Tuesday, so if anyone there
wants to meet me (in Eve or Amsterdam), there is
an opportunity. Just let it know!
Happy PostSharping!

Posted about 1 month ago by nor...@blogger.com (Gael Fraiteur)

I will present PostSharp at the next
Code Camp
taking place June 7th
in Krakow, Poland.

The talk will start with a general introduction to
AOP, then go to specific solutions using
PostSharp.

It is be a honor for ... [More] me to stand besides a
great speaker (and professional evangelist)

Chris Koenig.

If anyone of the Pole .NET community wants have
some more in-depth discussion or just have a
beer, I will be there till Sunday evening.

Happy PostSharping! [Less]

Announcing PostSharp 1.0 RC3

Posted about 1 month ago by nor...@blogger.com (Gael Fraiteur)

I am pleased to announce the third release candidate of PostSharp 1.0,
available for download. This
is also the last release candidate, which means that I would gladly promote
it to the status of stable release if no bug is ... [More] reported.

Indeed, RC2 proved to be very stable. Among the
reported issues, very few affected core
components. Most efforts have been directed to a
better integration with MSBuild and a better
packaging.

Let me cite a few improvements you can be looking forward:

Improved Compile-Time Performance: Compiling PostSharp samples
is 65% faster with RC3 than with RC2 if you use the standard Windows Installer.
No real magic here: since PostSharp is stable enough, we now ship the release
build instead of the debug build. Additionally, PostSharp is now correctly
configured to use native images.
Improved User Guide: There is now a full end-user documentation
of the PostSharp Platform and PostSharp Laos.
Improved Packaging: The installer does not place assemblies in
GAC any more. The no-installer package is now fully-featured with documentation
and samples.
Samples Browser: Documentation and source code of samples are
now better integrated. You can open a sample into Visual Studio directly from
the samples documentation browser.
Support for References to .NET 1.0: There is now a workaround
that makes PostSharp accept assemblies (generally third-party dependencies)
compiled for the .NET Framework version 1.0 or 1.1.
Compatibility with VSTS Unit Tests: VSTS Unit Test will not
complain of artifacts generated by PostSharp any more.

For a complete of resolved issues and implemented
features, please refer to
this listing in our issue tracker.

Happy PostSharping!
