Hi, I would like to manually create exports for composition, but the Export constructor only accepts a dictionary for metadata, while I should directly create it from the metadata object (IMyMetadata). Isn't there a way to create the dictionary from the object? Something like this: IDictionary<string, object> metadata = AttributedModel...

I have an ASP.NET MVC2 application that supports visualization plug-ins/providers. The IVisualization interface is defined in a common assembly which is referenced by both the ASP.NET MVC2 app, and any visualization providers.

I am building a Windows (Service) application that, in short, consists of a "bootstrapper" and an "engine" (an object loaded by the bootstrapper, which transfers control to it, and then performs the actual tasks of the application). The bootstrapper is a very basic startup routine that has few features that are likely to change. But the ...
What is the proper way to do that? Let's say we have some third party library in our project and we need to provide an access to some controls which are sealed. New widgets will be created and added to the application using MEF and they should be able to import some controls from the core application. So how to export those controls prop...
Scenario: I am using Managed Extensibility Framework to load plugins (exports) at runtime based on an interface contract defined in a separate dll.

I'm starting a new personal Prism 4 project. The Reference Implementation currently uses Unity. I'd like to know if I should use MEF instead, or just keep to Unity. I know a few discussions have mentioned that these two are different, and they do overlap, but will I be missing out if I simply choose Unity all the way? ...
I have MEF/Prism 4 project for which I can resolve imports via the ImportingConstructor, but not via field imports in the same class.

Same result whether it's a field or proper...

I know that MEF currently supports downloading XAP files from a URI (which is awesome!), but does anyone know if it's possible to have MEF load a XAP from a byte array? Thanks! ...
Hi, Does the Netbeans Rich-Client Platform Development provide the same in Java as MEF in .NET? Is there is any other built-in easy way in JAVA to do pluggable applications? Thanks ...
Hello, I am trying to figure out if MEF and moonlight work together. I heard Mono 2.8 got MEF already included. Although, will the full MEF work for moonlight applications? For now I am using this adapted moonlight library http://mefcontrib.codeplex.com/releases/view/35019. Although, some functionality is stripped or this library is...
