In this screencast we take a look at how we can provide defaults in a MEF CompositionContainer such that an application can be sure that it has an implementation of a plug-in if no additional plug-in is discovered by MEF. This leads to a discussion about ExportProviders and how they provide an extensibility point for MEF.[more ]

In this screencast, we look at an additional catalog in the Silverlight Toolkit Preview for Silverlight Beta 4, the PackageCatalog. This catalog adds the key ability of being able to download XAPs dynamically at runtime and ask MEF to discover and compose the types contained within those XAPs into a pluggable application.[more ]

In this screencast, we look at how composition of component parts in MEF is not necessarily a static or "one-time" process and that as changes are made to MEF's CompositionContainer it can re-compose components to take account of those changes.[more ]

In this screencast, we start to take a look at catalogs which provide one way in which MEF discovers the components that it can compose. We take a look at the catalogs built into the framework and what they do for us and also how MEF uses them to populate a default CompositionContainer & how you can take control of that.[more ]

In this screencast, we take a deeper look around using the MEF attributed programming model. We look at what we can import & export, required and optional imports, cardinality, creation policies and also how we can add our own metadata for differentiation.[more ]

In this screencast, we talk briefly around the idea of components having imports and exports and then we drop into Visual Studio 2010 and do a quick, "magic" demo of how MEF can plug together a couple of components for us. In later videos, we'll attempt to dig deeper into what MEF is doing and how we can take more control of it.[more ]

I've been chatting to Anthony and Jason from iMeta Technologies Ltd who have used Silverlight to build the iMeta Agility application for managing agile/scrum development projects.The guys talk through how they came to be building on Silverlight, give a demo of the application in action and then talk a little around their WPF background, patterns they're using and how they want your feedback on the current version to help plan where they take the app in the future.[more ]

Codify are based in Aberdeen, Scotland and build bespoke applications for the oil and gas industry. They've been on .NET since version 1 and have largely built desktop applications and deployed them in web-like manner via ClickOnce.Silverlight was then a natural fit for their recent applications and here we get some insight from their MD, Ops Director and one of their Senior Developers around the sort of applications that they've put together, what's driven them to use Silverlight, their…[more ]
