Silverlight 4, MEF and the DeploymentCatalog ( again :-) )

mtaulty — Tue, 09 Mar 2010 23:31:21 GMT

The Silverlight 4 beta came with a version of MEF that had 3 catalogs – namely AssemblyCatalog, TypeCatalog and AggregateCatalog . They’re pretty easy to understand and I made a screencast on the topic here . The Silverlight 4 preview toolkit came with a PackageCatalog that is really useful as it works with another class Package to download separate XAP files and expose their exported components to MEF. The new MEF drop on codeplex has an evolution of those classes called the DeploymentCatalog. I...(read more)

Just a quick plea. I’ve re-hosted my website with a new hoster so if you spot problems with the site please let me know as I’ll have no doubt forgotten to switch something on or off. Thanks. Normal service should now resume :-)...(read more)

Silverlight 4, Experiment with Pluggable Navigation and a WCF Data Service

mtaulty — Sat, 27 Feb 2010 06:15:13 GMT

Warning – bit of a sketchy post this one so apply a pinch of salt, just an idea I’ve been toying with… One of the things that I find a bit mind boggling about Silverlight 4 is the new support for pluggable navigation. I wrote about it a little here but there are a better series of posts on it over here on David Poll’s excellent site . The basic idea is that Silverlight 3 introduced the the Frame control. You tell the Frame control ( via its Source property or via its Navigate method ) to navigate...(read more)

Free Client Day at Microsoft TechDays UK – London, 15th April

mtaulty — Fri, 26 Feb 2010 01:56:28 GMT

I wanted to do a call out for the Client development day that we’re running as part of the UK TechDays event. This is a FREE event that’s running all day in London on the 15th April and it’s targeted at developers who are interested in hearing about client development with .NET Framework V4.0 and for Windows 7. The agenda on the website doesn’t quite do it justice in that we’ve managed to get some really fantastic speakers for this day; Specifically, there’s 2 full sessions of walking through features...(read more)

MEF, Silverlight and the DeploymentCatalog

mtaulty — Wed, 24 Feb 2010 01:10:37 GMT

I posted about the DeploymentCatalog in the new MEF preview the other day and I got a question or two along the lines of “show me an actual example rather than snippets” and so I thought I’d walk through a simple example here. Let’s say that I want to build a Silverlight application that has a need for a photograph to be provided by a user and I don’t really care how this photograph is captured. It might be captured from the webcam, it might be captured from the file system or drag-drop or anything...(read more)

Microsoft UK TechDays – London – April 12th to 16th

mtaulty — Wed, 17 Feb 2010 11:23:25 GMT

Ooh, check out those graphics :-) We’re putting on a week of free ( free, free, free ) technical events in London in the week of April 12th to 16th. There are two events every day with one focused towards the “IT Professional” and the other focused towards the developer.

The developer days line up looks like this; I’ve had a small hand...(read more)

Silverlight Bootcamp at MIX10

mtaulty — Wed, 17 Feb 2010 01:23:19 GMT

I’m doing a half-day “bootcamp” session with John Papa at MIX 10 and wanted to publicise that again here – if you’re already signed up for MIX then you can still revisit the pre-conference workshop registration and register for our session. If you’re not registered for MIX then registration is still open ( and reduced by $200 ) so that you can still grab a flight and come and get the detail on the Windows Phone developer story ( amongst many other things ) in person. Hope to see you there :-)...(read more)

New MEF Drop (Preview 9) on CodePlex!

mtaulty — Wed, 17 Feb 2010 01:11:05 GMT

I was pretty excited to see that there’s a new drop of MEF up on CodePlex – if you’re a reader here then you’ll know that MEF will ship with Silverlight 4 and with .NET Framework 4.0 ( it’s already in the beta/RC bits in both cases ) and there are versions on CodePlex targeting Silverlight 3 and .NET Framework V3.5 Sp1. The phrase that I like to use to describe MEF is that it is a; framework for composing applications out of a set of loosely coupled parts that are discovered and can evolve at run...(read more)

Silverlight 4 – Implicit Styles and Themes

mtaulty — Mon, 15 Feb 2010 17:31:39 GMT

I hadn’t really thought properly about implicit styles in Silverlight 4 although I wrote a little about it back here and it’s something that WPF always had ( if I remember correctly ). The bit that I hadn’t really thought about was how you could set up a set of implicit styles for all your controls, throw them into separate resource dictionaries and then just load one style or the other at runtime and push it into the MergedDictionaries property of your application’s ResourceDictionary . It’s fairly...(read more)

Silverlight 4 Beta Networking Screencasts

mtaulty — Mon, 15 Feb 2010 03:59:38 GMT

I’ve been putting together a session around networking in Silverlight and I wanted to get a little more re-use out of the work that I’d put into it so I thought I could quickly turn some of it into screencasts that go onto Channel 9. In Silverlight, applications are browser-initiated and ( usually ) have limited access to the local machine so being able to work on the network is key; whether that be ( as the picture suggests ) going to the site that the application came from ( the “site of origin...(read more)

Silverlight & MEF Talk from the London Silverlight User Group

mtaulty — Wed, 10 Feb 2010 01:44:30 GMT

Just a quick plug for a talk I gave last week at the London Silverlight User Group on the Managed Extensibility Framework in Silverlight 4. Ian Smith kindly recorded this with great skill and speed and has the video available if you click the picture below; The Silverlight User Group is growing really quickly – I’d say about 100 people turned up on the night which is all the room could take so I guess bigger venues are going to be called for in the future and it’s great to see so many people building...(read more)
