CAL and CAG
Day 1 Morning: Introduction
Lecture: Introduction to Prism. Problems addressed by Prism.
Goals and non-goals of the Prism framework. Advantages and disadvantages of loose
coupling. Common and uncommon usage
scenarios. Types of applications that Prism does well, types that it does not. Basic architectural layout of the Prism system, components of a Prism
application. Definition of basic terms. Analogies to CAB/SCSF and OLE. Concepts
of targeting both WPF and Silverlight.
Lab: Installation of Prism SDK. Exploration of its parts.
Day 1 Afternoon: Prism Application Walkthrough
Lecture: Walkthrough of Hello, World sample Prism application, in
WPF and Silverlight.
Examination of tools for
creating your own Prism application, guidance packages written by your
Examination of the Bootstrap class. Examination of UnityContainer and its
Resolve method, differences between WPF and Silverlight. Examination of
MEF injection container, differences from and similarities to Unity
Lab: Generate Hello, World application using instructor's templates. Make
changes, observe results.
Day 2 Morning: Services and Modules
Lecture: Concept of a module, implementing the IModule interface.
Using guidance package written by your instructor to add a module to your
project. Injection of container reference into modules. Different ways of specifying the module list: hard-wired,
directory sweep, web service. Preparing a module for remote downloading. Concept of a service: separation of interface and
implementation. Creating a service. Registering a service locally and globally.
Fetching and using services.
Lab: Work with sample application
manipulating services and modules.
Day 2 Afternoon: User Interface Composition with Regions and Views Using
Lecture: Need for loose coupling in the user interface. Definition of a
region. Examination of the Region Manager service. Adding a region to your
application. Examination of the IRegion interface. Creating a custom region.
Fetching a region and showing a view in it. Concept of a view and
view model. Creating and implementing a new view/view-model class. Using
pull-based and push-based composition for associating view with regions.
Lab: Work with sample application showing regions and views
Day 3 Morning: Shared User Interface Extension and Commands
Lecture: Need to integrate with WPF Command mechanism to respond to items
from the user interface, such as button clicks. Examination of the ICommand
interface. Declaring and creating a Command
object. Examination of the CompositeCommand and DelegateCommand classes. Connecting to the Command object via single and multicast delegates.
Local versus Global commands.
Using Command object to allow modules to show menus and toolbars and ribbons.
Example integrating Commands and Regions.
Lab: Work with sample application integrating events and regions.
Day 3 Afternoon: Event System and Testing of Prism Applications
Lecture: Problems of loosely-coupled notification. Introduction to
the Event Broker service. Characteristics of a Prism event. Static and dynamic
subscriptions to an event. Specifying the thread on which an event notification
is received. Static and dynamic firing of an event. Specifying the scope of a
fired event. Filtering on event parameters.
automated, continuous testing of applications to meet today’s software standard
of care. Discussion of different types of testing – lowest-level unit testing,
highest-level acceptance testing, and types in between. Examination of unit
testing strategies for modules and services in Prism. Use of mock objects for
injection into unit testing. Testing strategies for the model-view-viewmodel and
model-view-presenter stacks. Separation of activities that require human
intervention for testing; need for and strategies for minimizing this set.
Measuring and dealing with code coverage of testing in Prism. Designing Prism
apps for testability.
Lab: Work with sample application using
automated testing and loosely coupled events
