阅读更多关于 Whats the status of Prism integration in Autofac?

问题 Integration into Prism was talked about in the 2.1.x time frame, we are @ 2.4.x, Prism 4 is out now and the RIStockTrader Example in /contrib is just a default XAML project. Should it work? If so, anyone have a simple example of a Silverlight Shell + Bootstrapper + 1 Module they could point me to? 回答1: An updated Prism integration is currently in progress. I'm not sure what the status is exactly, but you can get the code and potentially contact the author here. You can also pass on feedback

阅读更多关于 Is it possible to write Prism apps such that they can be tested without the UI?

问题 Disclaimer: Prism Novice. I'm reading up furiously to make up for lost time though :) Context: I need to write automated acceptance tests for a WPF application built using Prism. Issues: I find that it is convoluted trying to compose the backing ViewModels and everything that they need without the UI. I may be wrong here...

问题 We are building a WPF Prism application. We have different developers working on different module projects, and multiple modules are injected into the main Application Shell. The main application is also a separate project. We also want to be able to use the modules in different applications. We do not want to have to name the Regions with the same names in every application. For instance, say we have a module to be used in two different applications. In one application, its developer may

问题 I am trying to get a Prism application to start up, and am getting a very strange error: InvalidOperationException: ServiceLocationProvider must be set. I am using MainWindow in the main (module host) application as the region for a single main shell, that has it's own regions. That way I can swap out main window layouts if needed. I get the error on the InitializeComponent(); call, the only line of code in the constructor of MainWindow . Google and Bing both return zero results for that

阅读更多关于 Displaying modal dialogs using PRISM 4

问题 I'm developing a .NET 4.0 application using PRISM and MVVM, as well as WPF. I currently have a shell subdivided in regions, with views inserted in them. When the user clicks on a button in one of the views, I would like a custom-made modal dialog to be displayed on top of all the views, but still within the same shell. I looked at the StockTrader RI example and their implementation of the RegionPopupBehavior. Basically, they created a dependency property which allows them to define regions

阅读更多关于 How to create a new view every time navigation occurs in PRISM?

问题 I'm using WPF4 and PRISM4 for my new project. There is a single module with several views in it. The DI is done with unity. When I navigate from ViewA to ViewB for the first time, the ViewB is created and its constructor is called. But when I try to navigate to ViewB for the second, third time, the ViewB is not created, but existing instance is reused. I'm using IRegionManager.RequestNavigate for my navigation purposes. I've tried to pass TransientLifeTimeManager to RegisterType Unity methods
