Prism MVVM - How to pass an IEventAggregator to my ViewModel

阅读更多关于 Prism MVVM - How to pass an IEventAggregator to my ViewModel

问题 recently I started working with Prism in Silverlight. I want to use the EventAggregator to Subscribe and Publish events between two ViewModels. As I saw on some guides, the ViewModel's ctor should accept IEventAggregator as a parameter. I can't find out how to do this hence my View always wants to initialize the ViewModel with a parameterless ctor. My ViewModel ctor: MyViewModel(IEventAggregator eventAggregator) { // get the event.... } My View: <UserControl ....> <UserControl.Resources>

阅读更多关于 Silverlight Prism Module Not Ready

问题 I'm building a Silverlight 4.0 application with Prism (a.k.a. Composite Application Guidance). I have two modules, both defined in my ModuleCatalog.xaml as WhenAvailable . My Application_OnStart instantiates my Bootstrapper and invokes it's Run() method. Well after my application is started and up and running (in fact, the user has to click a button in the UI), I then attempt to load the modules: foreach (ModuleInfo mi in moduleCatalog.Modules) ... Type moduleType = Type.GetType(mi.ModuleType

问题 Here's the business problem I'm trying to solve: Start with pages: Menu -> Activity -> Connect. When the user navigates from Menu -> Activity, if there is a specific piece of hardware not connected, I want to immediately Navigate to the Connect page.

阅读更多关于 'cannot be assigned to — is read only' yet has a setter?

问题 I'm getting a (to me) very weird looking argument exception. When calling this.MainViewModel.MyObject = new MyObject(..some parameters here..); , I get property or indexer 'IMainViewModel.MyObject' cannot be assigned to -- it is read only . I've been trying to find people with similar questions but everytime the answer is 'do you have a setter?'. Yes, I do have a setter. Yes, my property is public. I'm very confused as to why it is throwing a fit here. The property I'm trying to write to is;

Questions on MEF strategy and structure

阅读更多关于 Questions on MEF strategy and structure

问题 I am tasked with modularizing a C# app that is a rewrite of a very large Delphi app (the DB has 249 tables!). Business constraints proscribe a complete redesign for .NET and better overall architecture, so we are basically just incrementally rewriting module for module of the Delphi app in C#. Until finished, the suite will comprise a mixture of pending rewrites, and C# app modules I want to integrate using MEF. The app concerns itself with Time-and-Attendance and Access-Control, and has

Prism App Does Not Exit When Closed

阅读更多关于 Prism App Does Not Exit When Closed

问题 I am learning prism and I have hit a problem. I have made an app very similar to the one that Mike Taulty makes in is great tutoral about Prism. The biggest difference is that my app is a WPF app instead of Silverlight. I am finding that I have hit a problem though. When I close the main shell window, the app does not exit. The window goes a way, but the debugger is still active. I have tried looking for call stacks and such, but Visual Studio just tells me that it is "External Code". Any
