Sunday I leave to Vegas to attend my first MIX. It’s exciting to finally attend this event that has such an air of mystique around it. I’ll be speaking on how you can use MEF in SL4 to partition your applications across many XAPs in a fairly seemless fashion. My talk is short, but it’s going to be very...

This Thursday, I’ll be joining John Bristowe and Joey Devilla to talk about composite applications, patterns, MEF and anything else that comes up. I am flexible :-) This is a live webcast where questions will be taken in real time, so ask away! I am selfish but no slides or demo prep sounds great...

In the last post we migrated over to the new DeploymentCatalog. In this post we’ll look at refactoring the code to incorporate the MVVM pattern. Code from the last post is available here Why ViewModel? There’s a ton of content out there in the blogosphere that discuss the virtues of separated...

Continuing on with the series. In part III we introduced the concept of application partitioning through the use of the PackageCatalog which ships in the Silverlight toolkit. In this post we’ll take a look at a new API known as the DeploymentCatalog which ships in the box! We also look at some changes...

One of the questions we get quite often is “Why should I use MEF?” and “How can i use MEF?”. Fortunately one of our awesome field guys Mike Taulty has been rising to the occasion. He’s put together a great set of web casts on everything you wanted to know about using MEF in Silverlight 4. These are not...

In my last post I discussed how to export configuration. A follow up question in the comments was “What if the values change?” Meaning the values that are exported using the approach I illustrated are static. In the real world however values often can change based on some user setting etc. A variant...

<Goal>Post in 15 mins or less :-)</Goal> This question which recently popped on our forums is one of the common questions we hear from customers. In this particular case, wcoenen (the person in the forums) had recently used information that he wanted to pull from configuration and pipe to...

As you start to work with MEF one of the fundamental decisions you have to make is how MEF will be hosted. There are several factors which will impact your decision including whether you are building on Silverlight or the Desktop and whether you are building an application or a library. The first concern...

About a month ago I posted some ideas around MEF and Prism together. As part of the post, I presented 2 high-level scenarios for MEF/Prism integration (and there are likely more) Use Prism with MEF as an add-on for extensibility. That is make modules extensible through MEF. You can think of this as the...

Some posts titles just really grab you. I couldn’t help but think about one of those annoying ads in the back of magazine when I saw this post from Ayende. In actuality the article is more of a “How I can implement what I need from MEF in 2 hours” however that’s not as provocative...

In our last post we saw how using metadata in MEF allows us to provide additional self-describing information about exports. This has a range of uses including providing hints on how the export should be handled (such as UI location) as well as allowing us to filter out creating exports that we don’t...

In Part I of the series we built the basics of our dashboard end ended with our app displaying a single widget. In this post we’ll show two widgets, sensing a pattern here? :-) We will show two, but we’ll put them in different places on our dashboard. We’ll explore two ways of doing...

Now to the question, what is the story on Prism and MEF? I am getting asked this now several times a day, more so than the IoC question. I am happy to say we’re working with p&p to come up with a good answer. Note: This is still a work-in-progress, but here’s the thinking on this so far...

Note: This only applies to using MEF Preview 8 on Silverlight, it does not apply to MEF in Silverlight 4 Yes I know we never did a Preview 8 post but…… We found a bug in PartInitializer (thanks to Kathleen Dollard for finding it!) in Preview 8 which affects MEF in Silverlight. The bug resulted in the...

Andrew Kazyrevich has written an original blog post about NDepending Resharper . Or more precisely analyzing the code base and API of Resharper with NDepend and comparing the evolution between Resharper v4.5 and v5.0. You'll see some quantitative information include the facts that R# is a 0.5 M Lines...
