What I'm using: Visual Studio 2010 Microsoft .NET Framework 4 Prism v4 What I am trying to figure out is how to get started with Prism + MEF while maintaining the MVVM pattern. When I go into the Prism Quickstarts, it has a Prism + MEF, but the comments in the project specifically state that the Quickstart example does not implement MVVM. I'm not really sure what to mix/match so that my shell itself follows MVVM (and regions). Basically, I want to use MEF to be able to load Assemblies (Modules) at run-time. And, I want to setup regions in my Shell and have the Shell use MVVM (so I can databind

Will Microsoft Unity from Patterns and Practices be obsolete in 4.0 ? How does MEF compare to a framework like Unity? 回答1: Specifically addressed in the PDC 2008 2nd Keynote by Scott Guthrie, MEF has a lot more to do with things like extending Visual Studio 2008 and other applications, without having to use all the COM and older technologies... A very good demonstration of extending the text edition in VS2008 was shown among

How can this be done with Microsoft.Composition (MEF 2)? I can't find any Method for this purpose. 回答1: I will have a shot at this one. Granted, I am only about a week in on learning MEF 2 myself, after having some limited exposure to MEF 1. So, please take that in consideration with the following answer as it could be completely wrong. Also, I have found documentation very poor and out of

Because of the varied nature of the items it communicates and controls, I need to have a different "driver" for each different piece of hardware. This made me think that MEF would be a great way to make those drivers as plugins that can be added even after the product has been released. I've looked at a lot of examples of how to use MEF, but the question that I haven't been able to find an answer to is how to populate a MEF plugin with external data

I have been using the Windsor IoC Container for my web-based application, to resolve the data access layer implementation the application should use. The web application's UI will consist of pages, and each page consists of small units called portlets. (Their concept is somewhat similar to widgets.) These so-called portlets are basically web controls and can be configured in runtime for every page invidually. The application will ship with some of these built-in, but I would like to enable extending it easily. I figured out that this mechanism is exactly what MEF is built for. So I decided to

I am using prism framework in a silverlight app with multiple modules in separate XAPs. I have a resource dictionary defined in my in my shell project. In my modules I can use the resources fine, but since the modules are decoupled from the shell until they are loaded at runtime the designer does not show them or recognize them. Is there a way to make the modules aware of my resources at design time without merging my resource file in every view xaml? My resource files are in a "common" project. I think I have definitely solution for design-time resources. Benefits: It works in any module

I try for some time to get things done using MEF but now, I run into a problem i need help. Description: I have 2 DLL and one EXE file. ClassLibrary1 (LoggerImpl.cs, SomeClass.cs) ClassLibrary2 (ILogger.cs) WindowsApplicationForms1 (WindowsApplicaitonForms1.cs, Program.cs) I need any help or direction why this doesn't work ? // ClassLibrary1.dll //SomeClass.cs public class SomeClass { [Import("Logging", typeof(ILogger))] public ILogger Log { get; set; } <-- ALWAYS NULL ??? public void Print() { Log.Print(); } } // ClassLibrary1.dll // LoggerImpl.cs namespace ClassLibrary1 { [Export("Logging",

I have a system that uses MEF to load parts. Each of these parts rely on a core library. When I build the project, I add a version number to the .dll files like this: part1-1.0.0.0.dll part2-1.0.0.0.dll Also, there is an application that performs MEF composition. It also uses the core library. I've found that I can just deploy the "part" dlls, and composition works fine because the application has already loaded the core library that the parts rely on. So my file system looks something like this: /parts/part1-v1.dll /parts/part2-v1.dll composer-v1.exe core-v1.exe The trouble I'm having is how

Ŀ¼ 在传统的基于 .Net Framework 框架下进行的 MEF 开发，大多是使用 MEF 1 ，对应的命名空间是 System.ComponentModel.Composition 。在 DotNet Core 中，微软为了伟大的跨平台策略，引入了 MEF 2 ，其对应的命名空间是 System.Composition ，这个需要开发者自己在 Nuget 上进行下载安装 Microsoft.Composition 。2 与 1 相比，无论是在支持平台上还是性能上都有改进，值得我们探讨一下。 首先，我们创建一个 DotNet Core 控制台应用程序，然后为其添加 MEF2 对应的 Package：Microsoft.Composition； 然后，我们创建一个示例接口： public interface IMessageSender { void Send(string message); } 接着，我们再创建一个示例类来实现该接口，并尝试将其导出： [Export(typeof(IMessageSender))] public class EmailSender : IMessageSender { public void Send(string message) { Console.WriteLine(message); } } 最后，我们在主程序中进行调用：
