Master appsettings.json, Environment Overrides, User Secrets, Custom Providers, and Options Pattern in .NET 10 & ASP.NET

What you'll learn

⚡ Master Every Configuration Source: Read settings from appsettings.json, Environment Variables, Command Line, User Secrets, and In-Memory collections.
⚡ Control Precedence & Overrides: Understand the provider hierarchy and learn exact rules for how configuration keys override one another.
⚡ Type-Safe Binding & Options Pattern: Move beyond string keys by implementing IOptions, IOptionsSnapshot, and IOptionsMonitor
⚡ dvanced & Production Debugging: Inspect the complete runtime hierarchy using GetDebugView(), redact sensitive secrets, and handle custom key mappings.
⚡ Cloud & Docker Ready: Map nested JSON sections using OS environment variables (__) and build production-ready app configs.

Requirements

❗ Basic knowledge of C# and general .NET development concepts.
❗ A computer running Windows, macOS, or Linux with the latest .NET SDK installed.
❗ Visual Studio, Visual Studio Code, or JetBrains Rider.

Description

Most developers know how to read a simple string from appsettings.json, but real-world enterprise apps require much more. How do you safely handle production secrets? What happens when environment variables conflict with JSON settings? How do you update settings at runtime without restarting your app?
This course is a complete, hands-on guide to masteringASP.NET Core Configuration Architecture.
Whether you are building microservices, cloud-native apps for Docker/Kubernetes, or enterprise Web APIs, you will learn how to structure, bind, protect, and debug your application settings with confidence.
