Introduction and Screen Redesign
The speaker greets the audience and introduces a screen redesign, highlighting the stillness of co-workers and the combination of platforms like YouTube, Mixer, and Twitch. He discusses taking a break from Facebook due to family frustrations and distractions.
Limiting Facebook Usage
The speaker expresses his decision to take a break from Facebook due to time consuming and distracting usage habits, aiming to focus more on Twitter for a wider audience.
Engaging in Family Game Day
The speaker narrates a busy weekend involving a family game day event with various competitive games and a barbecue, emphasizing the importance of bonding with family.
Weekend Activities and Club Visit
The speaker shares his weekend activities, including attending a club for a friend's birthday, highlighting his tiredness and early wake-up the next day to continue working.
Starting a Full-On Project
The speaker discusses planning to start a full project focused on Outlook, explaining the challenges and features the application entails, emphasizing the use of Prism for easier implementation.
Creating Modules in the Project
The speaker explains the concept of modules in Prism, dividing the project into separate functional areas like mail, contacts, and calendar. He demonstrates the process of creating and initializing modules.
Designing the Shell of the Application
The speaker begins designing the application shell resembling Microsoft Outlook, incorporating elements like the ribbon, outlook bar, and region management for injecting views.
Introduction to Prism and UI Architecture
Explanation of how Prism is more of an application architecture library than a UI library, with a focus on using regions as placeholders for injecting views into elements.
Placeholder for Content
Detailed explanation of regions as placeholders for injecting content, demonstrating how views can be injected into the content region.
Comparing Prism to Angular
Comparison of Prism to Angular as frameworks for building WPF applications and single-page JavaScript applications, highlighting similar concepts.
Injecting Views into Content Regions
Walkthrough of injecting a view into the content region, including initializing and registering the view with the region manager.
Explanation of Regions in Content Control
Explanation of how regions behave as placeholders for views, allowing content to be injected without the view module having knowledge of the control structure.
Creating Region Names
Process of creating region names like 'Outlook Group Region' and 'Ribbon Region' to designate areas for injecting content.
Setting Themes for User Interface
Demonstration of setting themes for the user interface, specifically implementing the 'Office 2013' theme for a cleaner look.
Handling Region Adapters
Discussion on the importance of region adapters for controls like the 'Outlook Bar' and 'Ribbon' to enable Prism to adapt incoming views to these components.
Creating Region Adapters for Custom Controls
Step-by-step guide on creating region adapters for custom controls like the 'Outlook Bar' and 'Ribbon' to allow Prism to adapt views to these components effectively.
Adding Region Adapters to Registry
Process of adding region adapters to the registry and resolving them to ensure that Prism can handle custom controls like the 'Outlook Bar' and 'Ribbon.'
Dependency Injection Container
Explains the concept of inversion of control with the help of a dependency injection container to automatically construct and inject objects based on type mappings. Demonstrates registering types with the container and the ease of using DI containers for object creation without explicit instantiation.
Avoiding Service Locator Pattern
Discusses the importance of avoiding the service locator pattern in dependency injection due to testability issues and hidden dependencies. Emphasizes the use of DI containers for better code maintainability and testability.
Registration with DI Container
Explains the role of modules in registering types with the dependency injection container and creating objects from the container. Highlights the benefits of using Prism for Inversion of Control (IoC) without explicitly managing object creation.
View Discovery in Prism
Describes the concept of view discovery in Prism where views are automatically created and added to regions based on type registration. Emphasizes using view discovery for static UI elements and immediate display requirements.
Outlook Bar Group Registration
Demonstrates the registration of an Outlook bar group with the DI container and injecting views from different modules into regions. Illustrates the power of loose coupling and flexible UI composition using Prism in WPF applications.
Contacts Group Integration
Integrates a contacts group into the application by registering views with the DI container and updating the UI dynamically. Showcases the ease of adding new modules and regions to the application with Prism.
FAQ
Q: What is the purpose of the speaker discussing his weekend activities?
A: The speaker discusses his weekend activities to provide context and emphasize the importance of balancing work and personal life.
Q: What is the significance of the speaker taking a break from Facebook?
