Piotr Włodek's Tech Blog: Introducing convention based programming for Managed Extensibility Framework

posted by

http://pwlodek.blogspot.com/ 604 days, 2 hours, 17 minutes ago

More than a year ago my friend @TheCodeJunkie wrote a very nice addition to Managed Extensibility Framework – the ConventionCatalog. Since then it’s a part of MefContrib project. However, I haven’t seen many people using it. My guess is that there is no much information about it, besides this post. So in this post I will discuss what a convention model is, and how to use it!

Piotr Włodek's Tech Blog: Isolating MEF components

posted by

http://pwlodek.blogspot.com/ 604 days, 2 hours, 19 minutes ago

What Managed Extensibility Framework does well is component discovery and composition . This is not a big surprise as it was designed to do so. However, one particular area where MEF has nothing to say about is component isolation. This post discusses how to write a simple ComposablePartCatalog which provides isolation for MEF components!

Creating a Markup Extension for MEF with Silverlight 5 - Jeremy Likness

published 764 days, 3 hours, 45 minutes ago posted by

iftekharahmedamit 764 days, 20 hours, 38 minutes ago

One exciting new feature of Silverlight 5 is the ability to create custom markup extensions. Markup extensions are a part of XAML. Whenever you see a notation that starts and ends with a brace, you are viewing a markup extension. Markup extensions exist to pass information to properties in the XAML that the XAML parser can use when generating the object graph. A commonly used example of markup extensions is the data-binding syntax. In the following XAML snippet, the data-binding uses a markup extensi... (more)

Some time ago I developed a small chunk of code which enabled Unity and Managed Extensibility Framework to consume each others components. (...) So in this post I want to discuss a simple adapter for Castle Windsor which is built using MefContrib IoC goddies and enables MEF to consume components registered in the Castle Windsor container.

There’s an interesting new component in the Microsoft .NET Framework 4 specifically designed to provide an effective answer to an evergreen question: How would you write extensible applications that can discover at run time all the parts they’re made of? As Glenn Block explained in his February 2010 article, “Building Composable Apps in .NET 4 with the Managed Extensibility Framework” (msdn.microsoft.com/magazine/ee291628), the Managed Extensibility Framework (MEF) can be used to streamline building com...

MEF (Managed Extensibility Framework) in .NET 4.0

http://agafonovslava.blogspot.com/ 945 days, 3 hours, 57 minutes ago

What is MEF (Managed Extensibility Framework). For example you have an accounting application and you would like to provide a hook (socket) where external vendors can connect (plug) and add invoicing capabilities to the accounting application. For instance you have application which you would want different vendors to connect with their features and extend your application. So the vendors just put the components in the application, the application discovers them and does the connection. (more)
