In preparing for an upcoming talk I'll be giving on the Managed Extensibility Framework (MEF), I wanted to demonstrate how fast and easy it is to use in a sample, reference application. This application creates a dynamic plugin. I first link a plugin and show it active, then I create a second plugin and show how it is dynamically added to the program during runtime. It all takes under 10 minutes and would be faster if I didn't want to pace the demo to show the steps involved.

Nice demo for devs. I can see myself using this when our clients need our custom developed solution to be extensible.
ReplyDeleteI'd like to know:
1. How does it handle multiple versions of the same assembly e.g. where some code that started with the old version must complete using the old version but code that starts now must use the current plugin version.
2. How would you secure the plugin assembly (e.g. in Firefox where malware is targetting the plugin)?
1. Extended interface?
ReplyDelete2. That's something you'd need to do using signing or some other mechanism to validate the plugin before allowing it to "play."
Is there supposed to be no sound?
ReplyDeleteYes - no sound. :=)
ReplyDeleteNice example...
ReplyDeleteHow do you would distinguish what plugin to execute from some logic? Metadata? Some nice additional example? Thanks
Sure ... follow my "MEF" tags and you'll see some posts. The region management/Prism-related ones have specific examples of using metadata to filter imports.
ReplyDeleteThat's exactly what I need for my dissertation.
ReplyDeleteThank you.
