The important thing to remember is that every time there is a Binding, there is a linkage to the view model for this view. The above will add a new listview that will display a list of customer names and a button to load the list. Go to MainWindow.xaml and add the following markup as the content for the.

There are some other classes that make it simple to handle buttons from within the view model as opposed to writing an event handler in your code behind.įirst there needs to be some controls added to the view. It has a base class that handles the INotifyPropert圜hanged infrastructure that publishes changes from the view model to the view. WPF is well setup to use an MVVM pattern and Prism helps a lot with this. There isn't much here yet, but there are lots of things that Prism can help out with, such as breaking up the app into manageable chunks, navigation and implementing the MVVM patterns. public partial class App : PrismApplicationĪt this point, the app can be built and run and should look like the following: The Container property of the App class should be used to create the window as it takes care of any dependencies. This is the method that will create the main window of the application. The second method that has to be implemented is the CreateShell method. It should be noted that the Container can also resolve concrete types without a prior registration. A similar method is RegisterSingleton that will create a single instance at the time the dependency is made and not before. In effect the implementation of the registered interface is a singleton. RegisterInstance will register a created instance of an object against an interface. IContainerRegistry has other functions for registering against interfaces as well. protected override void RegisterTypes(IContainerRegistry containerRegistry)

In the App.RegisterTypes function, a registration would be made to create a DbCustomerStore every time an object takes a dependency on ICustomerStore. Objects in the app, such as view models, that have a dependency on the customer data would require an ICustomerStore object. Public class DbCustomerStore : ICustomerStore It might look something like this: public interface ICustomerStore For example, there might be an interface to read customer data from a persistent store of some kind and the implementation of it is to use a database of some kind. This function is used to register any app dependencies. There are a pair of abstract methods defined in PrismApplication that must be implemented first: RegisterTypes and CreateShell. Public partial class App : PrismApplication Otherwise, you will end up with two window instances.

Next, navigate to the code-behind file and update the class definition.ĭon't forget to remove the StartupUri property from the PrismApplication tag. In the snippet above, notice that line 6 has been added to define the namespace and that the App object has been updated to derive from PrismApplication. Navigate to the App.xaml and replace the standard WPF Application class with the Prism PrismApplication class. The next step in getting started is to subclass the Application object contained in the newly created WPF project. Installing one of the above packages will also take care of installing the packages for the container as well as the shared Prism packages.

Note: There is no need to explicitly install any other dependencies. For the purposes of this documentation, Unity will be the container of choice. At this point, a choice needs to be made, and that is which container to use for managing dependencies. Next up is to install the appropriate nuget packages. Install the Nuget PackagesĬreate a brand new WPF application in Visual Studio. If you aren't, consider taking a moment to do a bit of research on it first. An understanding of the Model-View-Viewmodel (MVVM) pattern is helpful as well as WPF lends to that pattern very easily. This guide assumes that you have some knowledge of the structure of a WPF application project and some comfort with C#. Follow the steps below and you will be up and running quickly with the start of a modular and easy to maintain app.
Getting started with Prism is pretty easy.
