Microsoft Windows Presentation Foundation (WPF) (4035) — Lesson 1: WPF Architecture, XAML and Layout

Learning Objectives

• Explain the WPF application model, visual tree, dependency properties, routed events, and XAML
• Create windows and responsive layouts with panels, controls, sizing, alignment, and navigation
• Validate wpf architecture, xaml and layout decisions with documented requirements, test evidence, risk controls, and measurable acceptance criteria

Detailed Topics

• Explain the WPF application model: Explain the WPF application model, visual tree, dependency properties, routed events, and XAML
• Create windows and responsive layouts with panels: Create windows and responsive layouts with panels, controls, sizing, alignment, and navigation
• Validate wpf architecture: Validate wpf architecture, xaml and layout decisions with documented requirements, test evidence, risk controls, and measurable acceptance criteria

Guided Demonstration

1. Review the requirement, users, data, dependencies, permissions, risks, and expected result.
2. Demonstrate the relevant configuration, creation, administration, analysis, migration, or development workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, test results, and other useful evidence.
4. Compare the observed result with acceptance criteria and explain any corrective action.

Hands-On Activity

Build a structured WPF interface from a defined screen requirement.

• Document assumptions, prerequisites, and the planned sequence before starting.
• Complete the activity and preserve evidence of normal, boundary, and failure behavior.
• Record issues, corrective actions, reusable notes, and the next improvement priority.

Scenario Analysis

• Identify the business or technical decision that must be made.
• Compare valid implementation approaches and their trade-offs.
• Consider security, privacy, accessibility, performance, support, and operational impact.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, data, permissions, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, ownership, user impact, and business continuity.

Validation Checklist

• The requirement, scope, inputs, and expected outcome are clear.
• The selected design or configuration is documented and follows approved standards.
• Normal, boundary, failure, security, accessibility, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply WPF Architecture, XAML and Layout in a realistic scenario and validate the result with documented evidence.
