PostSharp 2.0 CTP1 Updated - Visual Studio 2010 Beta 2 and .NET 4.0 Supported

Gael Fraiteur — Wed, 21 Oct 2009 04:12:18 PDT

We have refreshed PostSharp 2.0 CTP with a bunch of bug fixes and, most importantly, support for Visual Studio 2010 Beta 2 and .NET 4.0 Beta 2.

The PostSharp Add-In for Visual Studio currently don't work with Visual Studio 2010, but you should be able to build projects targetting all versions of the .NET Framework.

Note that the pipe server currently does not work with .NET 4.0.

Happy PostSharping!

Announcing PostSharp 2.0 CTP1

Gael Fraiteur — Fri, 09 Oct 2009 23:14:22 PDT

PostSharp 2.0 CTP1 it out! You can
download it
today.

As you understood from my previous posts, PostSharp 2.0 is no disguised minor
upgrade. PostSharp 2.0 brings major innovations not only to the .NET community,
but also to the aspect-oriented programming (AOP) community in general.

The design objective of PostSharp 2.0 is to
provide a powerful, robust and supportable platform for build-time
aspect-oriented programming for the next 5 years, with high focus on
extensibiliRead More...

Introducing PostSharp 2.0: #5 - Build Performance and Packaging

Gael Fraiteur — Thu, 08 Oct 2009 03:52:03 PDT

Let me finally discuss some changes in product packaging; they will are
important for performance and reliability.

Understanding the Build Performance Issue

Many people complained about PostSharp performance and wondered if the new
release would bring some improvement. The short answer is: yes.

The computing cost of PostSharp can be broken down into the following items:

Initialization Time. It takes time to start a CLR
process, load assemblies in the AppDomain, JIT-compRead More...

Introducing PostSharp 2.0: #4 - Visual Studio Add-In

Gael Fraiteur — Wed, 07 Oct 2009 22:24:52 PDT

So you are sold. You started using aspects in your new project. After many
months of development, the project gets larger and larger. You started with
rather simple aspects like tracing, but now your code is fully aspect oriented.
You have Resharped or DevExpress tool to help you navigate your code. But,
still, something is missing: you can't answer the following questions:

How do I know to which code elements my aspect has been applied?
How do I know which aspects have been applRead More...

Introducing PostSharp 2.0: #3 - Aspect Dependencies

Gael Fraiteur — Wed, 07 Oct 2009 21:12:13 PDT

We in the Microsoft .NET community are lucky: at critical moments, we are a few steps
behind the Java community. So we got C# and .NET after them, but we learned from
their mistakes, and got better language and platform. The same with AOP. AspectJ is widely used
over there, there is
plently of feedback, and PostSharp has been designed accordingly.

One of the questions engineers face when applying aspects to large software
is: how do you ensure aspects don't collide? This was Read More...

PostSharp At PRIO.Conference 2009, Munich, Germany, 28th October

Gael Fraiteur — Tue, 29 Sep 2009 04:05:34 PDT

I will be present as a speaker at PRIO.Conference 2009 in Munich, Germany, 28th of October 2009. My session is at 17h30. It will be the first presentation of PostSharp 2.0 ever and I will show some concrete aspects useful in GUI applications.

I will be in Munich from the 27th evening to 29th afternoon, so feel free to take a date if you want to meet me there.

Introducing PostSharp 2.0: #2 - Amazing Runtime Performance Enhancements

Gael Fraiteur — Thu, 24 Sep 2009 05:22:46 PDT

In my

previous post, I have given a quick overview of some new features of the
aspect weaver.

Equally important to features: runtime performance.

PostSharp 1.5 already did a great job compared to other aspect frameworks.
However, this could still be greatly improved. And this had been done in
PostSharp 2.0.

Take, for instance, a rather simple aspect: a performance counter. Say we
want to increase a counter every time a method is executed. The easiest and most Read More...

Introducing PostSharp 2.0: #1 - NotifyPropertyChanged

Gael Fraiteur — Mon, 14 Sep 2009 07:50:17 PDT

Be seated safely before reading on. This kicks ass.

I have already written enough abstract words in previous posts; let's now
introduce PostSharp 2.0 on a real example: the implementation of
NotifyPropertyChanged, one of the most frequently used patterns for all adepts
of MVC designs.

It's not just about implementing the INotifyPropertyChanged interface; it's
also about modifying every property setter. It's deadly simple and deadly
boring. And gets yRead More...

Generic constraints for enums and delegates

Gael Fraiteur — Thu, 10 Sep 2009 21:03:01 PDT

Yesterday, C# MVP
Job Skeet blogged about a
way to add generic constraints for enums and delegates. He noticed that,
while the C# compiler forbids such constructions, it is perfectly possibly in MSIL.
And he is fully right with this.

Jon uses a post-build step to add modify generic constraints.
His process: ILDASM, then find-and-replace, then ILASM. That’s possible because
the requirement is pretty easy.

But here he challenged me:

I've looked at
PostSharp andRead More...

PostSharp 2.0: Design Objectives

Gael Fraiteur — Fri, 04 Sep 2009 03:19:30 PDT

Before starting to blog about new features of PostSharp 2.0, it's good to remind the design objectives of this release.

Stated in one sentence: PostSharp is the leading aspect framework for .NET and will remain.

This was already true with PostSharp 1.5. In next version, the distance between PostSharp and other frameworks will be huge. You will judge by yourself in next posts.

Backward compatibility

As everyone knows, being the leader comes with greater responsibilities. And Read More...

5th Anniversary of PostSharp - History and Prospects

Gael Fraiteur — Tue, 01 Sep 2009 03:14:11 PDT

Although PostSharp and aspect-oriented programming are still considered new by most of the .NET community, it's already been five years this month since I started the project. It's a good opportunity to look back, explain how the project started, what it has become, and where it goes.

Reasons to Start

PostSharp started at the end of summer 2004 when a colleague drew my attention to aspect-oriented programming. AspectJ was already popular in the Java ecosystem; there were a multitude of sRead More...

Follow us on Twitter

Gael Fraiteur — Tue, 04 Aug 2009 04:36:46 PDT

Not every news deserves to be blogged about. That's why Twitter has been created, so let's use it!

Among other tweets, we will send a notification whenever a bug is resolved, so that you immediately know that a new development build is available.

Happy PostSharping!

PostSharp+Silverlight on MSDN Webcast (German)

Gael Fraiteur — Fri, 31 Jul 2009 03:50:51 PDT

Gregor Biswanger has posted a demonstration of PostSharp with Silverlight on MSDN Webcast (German language).

Die aspektorientierte Programmierung unter Silverlight ermöglicht es, nicht-funktionale Anforderungen als Aspekte getrennt von der funktionalen Anforderung zu entwickeln, zum Beispiel Validierungen, Sicherheit, Performance und Wartbarkeit. Dadurch wird der spätere Source-Code übersichtlicher und somit besser wartbar, außerdem wird durch die ZentralisierRead More...

Announcing PostSharp 1.5 RTM and PostSharp 1.0 SP2

Tue, 28 Jul 2009 08:53:41 PDT

I am pleased to announce the general availability of PostSharp 1.5 RTM, available for download today. This is an important milestone, meaning that PostSharp 1.5 is now stable and ready for production. The release candidate cycle has been pretty tranquil, with only two bugs reported in the previous build. The number of downloads of PostSharp 1.5 has actually exceeded the one of PostSharp 1.0 for three months.

Following our policy to maintain a single stable branch of the product, PostSharRead More...

New online documentation system

Gael Fraiteur — Sat, 25 Jul 2009 02:01:02 PDT

The online documentation web site http://doc.postsharp.org/ has been completely revamped with a new engine. The new documentation system offers online most of the functionalities of Microsoft Document Explorer: a synchronized TOC, an index, and a full text search.

The new website is powered by Help Server 2.0, an excellent product by x-tensive.com.

X-tensive is a long-time partner of PostSharp, now included in their flag product DataObjects.NET 4.0.

Would you get into difficRead More...

Log4PostSharp now for PostSharp 1.5

Gael Fraiteur — Sat, 25 Jul 2009 01:54:15 PDT

I am please to announce that Log4PostSharp, one of the favorite plug-ins to PostSharp, has been ported to PostSharp 1.5 by Mark Kharitonov. The initial version, targetting PostSharp 1.0, has originally been contributed by Michal Dabrowski.

Log4PostSharp implements tracing aspects for the popular framework log4net. But unlike what you could achieve easily using PostSharp Laos, Log4PostSharp injects optimal instructions with minimal overhead. You could difficulty write better code byRead More...

Good Data is now online!

Gael Fraiteur — Tue, 07 Jul 2009 23:27:25 PDT

I am pleased to announce that Good Data is now live and production-ready. Good Data provides data analytics online, as a service (Cloud Business Intelligence).

What's in common with PostSharp, you may argue?

I contracted for Good Data a few months in their early days. It was a great opportunity to meet Roman Stanek and Zdenek Svoboda, two famous serial company creators (NetBeans, now Sun's IDE for Java, and Systinet, eventually acquired by HP). Observing how they run startupRead More...

Announcing PostSharp 1.5 RC2

Gael Fraiteur — Tue, 30 Jun 2009 14:00:00 PDT

I am pleased to announce the release of PostSharp 1.5 RC2, now available for download.

This release fixes 10 issues of minor importance, of which two (357 and 358) should be tested by the community before the branch 1.5 can be labeled as stable.

By the end of the month, I hope to publish the stable release.

Happy PostSharping!

Improved support for ASP.NET in PostSharp 1.5 RC1

Gael Fraiteur — Mon, 11 May 2009 14:00:00 PDT

I forgot to mention it in the last announcement: support for ASP.NET web sites has been polished and is now fairly easy. If you installed PostSharp on your machine using the installer, enabling it on your ASP.WEB web site project is done in two steps:

Add references to PostSharp.Public.dll, PostSharp.Laos.dll and PostSharp.AspNet.dllAdd the following stuff to your web.config:<configuration>

Announcing PostSharp 1.5 RC1

Gael Fraiteur — Sun, 10 May 2009 14:00:00 PDT

I am pleased to announce the availability of PostSharp 1.5 RC1. This is a true feature-complete release candidate; it meets the quality standards of a real release.

Upgrade from 1.0 Recommended?

If your project is still in development phase, and will be for the next 2 months, I recommend making the upgrade from 1.0 to 1.5 now. The 1.5 branch has to many respects a higher quality level than the 1.0 branch. The last CTP proved to be pretty stable and only little important bugs were reporteRead More...
