Developing Windows Communication Foundation Solutions with Microsoft Visual Studio — Lesson 4: WCF Extensibility, Diagnostics, and Solution Review

Learning Objectives

• Extend behaviors, inspectors, formatters, routing, and service capabilities
• Use tracing, logging, diagnostics, testing, and performance evidence
• Validate architecture, deployment, support, and improvement actions

Guided Demonstration

1. Review the requirement, environment, dependencies, roles, risks, and expected result.
2. Demonstrate the relevant configuration, development, analysis, or support workflow.
3. Capture settings, outputs, logs, screenshots, code, or test evidence.
4. Compare the observed result with the acceptance criteria and identify gaps.

Hands-On Activity

Complete an enterprise WCF solution review and troubleshooting runbook.

• Document assumptions and the planned sequence before making changes.
• Complete the activity and preserve evidence of normal and exception behavior.
• Record issues, corrective actions, and reusable operational or development notes.

Troubleshooting Focus

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

Validation Checklist

• The requirement and expected result are clear.
• The selected configuration, design, query, code, or process is documented.
• Normal, boundary, failure, security, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply WCF Extensibility, Diagnostics, and Solution Review in a realistic scenario and support the result with documented evidence.
