Introduction To PRISM
Prism is a framework for building loosely coupled, maintainable, and testable XAML applications in WPF, and Xamarin Forms. Separate releases are available for each platform and those will be developed on independent timelines. Prism provides an implementation of a collection of design patterns that are helpful in writing well-structured and maintainable XAML applications, including MVVM, . Jul 01, · Prism is a framework that enables development of loosely coupled applications that are flexible, maintainable and easy to test. Prism applications are made up of modules – loosely coupled functional units that encapsulate portions of an application's overall functionality. In a team setting, modules can be individually developed, tested and deployed, thus minimizing cross-team Reviews: 6.

Microsoft, who run the project, describe it as. Even after reading the more detailed descriptions out there, I have next to no clue what it's actually about, I'm afraid. I'm hoping here that someone could give me a clear succinct explanation of what Prism actually is and why I should learn it.
I have been a WPF developer for a couple of years now, used MVVM my fair share, and have lately encountered people using Prism, but personally feel a bit out of the loop here. Does it include any libraries, if so for what exactly? Its intended to provide guidance on the best practices for building large scale applications which are flexible in terms of development and maintainability.
It is a book, but also includes the libraries for support on the GitHub site. Yes and no. It's worth taking a look at how they do things. They have a very elaborate "region" concept, as well as good event aggregation support. You should post another question with specific details so you can get some specific answers. For small projects with you as the sole developer, you may not need the abstraction and tools that it provides.

It's actually a fairly complex thing, too - Prism tries to fill a lot of needs, so it's tough to get a single "right" answer if you're trying to figure out its purpose.
It really does multiple things. This similar question asked by me is also having some good answers to this question - stackoverflow.

Noldorin: I'm assuming your asking about inside of Prism Prism does have good notification object and commanding support, which is really the only things missing in the BCL you really need for MVVM.
It doesn't have what is mexican phentermine called of the "extra" stuff provided by some MVVM "frameworks", such as a messaging framework, etc. In order to follow Prism guidance it is mandatory the libraries have been installed?

Client Application Development Challenges
Prism is the Microsoft Patterns and Practices Team official guidance for building "composite applications" in WPF and Silverlight. Its intended to provide guidance on the best practices for building large scale applications which are flexible in terms of development and maintainability. Feb 22, · Prism is also known as Composite Application Guidance for WPF and Silverlight. It is a framework that can be used to build Silverlight apps and WPF. It has been designed to build solid applications in Silverlight and WPF that normally have a single code base. It is helpful in developing a client application, which is in a modular fashion. Apr 06, · Prism is a framework to build composite applications using WPF + MVVM. When we develop composite applications, they should have.
Before reading this article, I will recommend that you read and understand the below concepts. If you know this information already that is enough to understand this article. When we develop composite applications, they should have: Ability to extend Flexibility Ability to reuse modules which are developed Top quality Ability to test modules independently Prism framework is strongly recommended to achieve the above-mentioned abilities.
Below is the design which we are going to implement. Here we can see 3 main components: Shell: This is the one, which will act like a showcase to all modules. All modules can be loaded here. BootStrapper : This is the one which connects the modules to Shell. Modules: Modules are those, which can be developed independently.
Using MVVM design pattern to build these modules is recommended. Now we will start implementing. Create a solution with WPF application project. Prism framework can be installed using nuget command: nuget command: install-package Prism. UnityExtensions -v 4. Windows; namespace Prism. FYI we can split any number of regions based on our requirement. In the below code we can see that we have used unity framework to resolve dependency issues and we have overridden 2 methods.
Modularity; using Microsoft. UnityExtensions; using System. InitializeModules ; Application. ComponentModel; namespace Prism. Install Prism framework using nuget command: nuget command: install-package Prism. In the below code we inherited interface IModule and we have provided implementation for Initialize Method.
Regions; using Prism. View; namespace Prism. For your reference I have uploaded Solution Project. At the end BootStrapper looks like below: using Microsoft. UnityExtensions; using Prism. ModuleA; using Prism. ModuleB; using Prism. ModuleC; using Prism. ModuleD; using System. AddModule typeof AModule ; moduleCatalog. AddModule typeof BModule ; moduleCatalog.
AddModule typeof CModule ; moduleCatalog. View All. Nagaraj M Updated date Apr 06, When we develop composite applications, they should have:. Ability to extend Flexibility Ability to reuse modules which are developed Top quality Ability to test modules independently.
Shell: This is the one, which will act like a showcase to all modules. Add the below code in PrismShell. For now I will explain with 4 regions called:. Add AModule class and the below code. Next Recommended Article. Classes And Objects. NET Core.
