C# and Microsoft Graph: Access and Automate Microsoft 365 with the Microsoft Graph API and .NET
Unlock the full potential of Microsoft 365 programmatically and transform your development capabilities
In today's interconnected digital workplace, Microsoft 365 stands as the backbone of enterprise productivity. Yet many organizations only scratch the surface of its capabilities. What if you could programmatically access and automate every aspect of Microsoft 365—from managing emails and calendar events to manipulating files, automating Teams interactions, and controlling user permissions—all through elegant C# code?
This comprehensive guide reveals how Microsoft Graph—the gateway to Microsoft 365 data and services—can revolutionize how you build applications and automation solutions.
Whether you're a seasoned C# developer looking to expand your cloud skills, an IT professional tasked with Microsoft 365 automation, or a solutions architect designing integrated enterprise applications, this book provides the knowledge and practical skills you need to master Microsoft Graph with C# and .NET.What You'll Learn:

• Fundamentals of Microsoft Graph architecture and how it unifies access to Microsoft 365 services
• Step-by-step Azure app registration and configuration for secure API access
• Implementing robust authentication using the Microsoft Identity platform
• Building, testing, and troubleshooting API calls with best practices for error handling
• Advanced integration techniques for Outlook, OneDrive
• User and group management through the Directory API
• Creating professional ASP.NET Core applications that leverage Microsoft Graph
• Designing background services for automated workflows and scheduled tasks

Why This Book Stands Out:

• Practical, Code-First Approach: Every concept is accompanied by real-world C# examples you can adapt for your projects
• Progressive Learning Path: Builds from fundamentals to advanced scenarios in a logical sequence
• Complete Authentication Coverage: Master both delegated and application permissions with various authentication flows
• Modern Development Techniques: Utilizes the latest .NET features and Microsoft identity libraries
• Troubleshooting Expertise: Includes dedicated sections on resolving common authentication and API challenges
• Production-Ready Patterns: Learn enterprise-grade practices for security, scalability, and reliability

The book combines theoretical understanding with hands-on implementation, ensuring you not only learn how Microsoft Graph works but can immediately apply this knowledge to solve real business problems.Perfect For:

• C# developers expanding into cloud and Microsoft 365 development
• Systems integrators connecting line-of-business applications with Microsoft 365
• Developers transitioning from older Microsoft APIs to the Graph ecosystem

Beyond The Basics:
While other resources might introduce you to Microsoft Graph, this book takes you through the complete development journey—from understanding the Graph's capabilities to building sophisticated, production-ready applications. You'll master practical skills like implementing delta queries for efficient data synchronization, handling throttling scenarios, working with batch requests, and securing sensitive Microsoft 365 data.
By the final chapter, you'll possess the expertise to design, build, and deploy professional applications that seamlessly integrate with the entire Microsoft 365 ecosystem—enhancing productivity, enabling automation, and unlocking new possibilities for your organization or clients.
