SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you access strongly-typed System.Text.Json metadata and apply .NET 11 naming behavior without relying on exception-driven, untyped APIs.

Core Features & Use Cases

  • Typed JsonTypeInfo<T> retrieval: Fetch strongly-typed serialization metadata for a specific type using GetTypeInfo<T>.
  • Safe metadata probing: Check whether type metadata is available without throwing by using TryGetTypeInfo<T>.
  • PascalCase property naming: Use JsonNamingPolicy.PascalCase to serialize object properties with PascalCase names, matching common API contracts.

Quick Start

Tell the AI: "Show me how to use JsonSerializerOptions.GetTypeInfo<T>() and JsonNamingPolicy.PascalCase in a .NET 11 Web project for serializing a record."

FAQPage Schema
How do I get strongly-typed JsonTypeInfo in .NET 11 without throwing exceptions?▼

Use JsonSerializerOptions.GetTypeInfo<T>() to retrieve strongly-typed JsonTypeInfo<T> for JSON serialization. For safe probing, JsonSerializerOptions.TryGetTypeInfo<T>(out ...) checks metadata availability without throwing, replacing untyped APIs.

How do I enforce PascalCase property naming with System.Text.Json in .NET 11?▼

Apply JsonNamingPolicy.PascalCase to JsonSerializerOptions to serialize object properties with PascalCase names. This ensures consistent property naming across models matching common API contracts in .NET 11+ applications.

Does .NET 11 support typed metadata lookup for JSON serialization?▼

Yes, .NET 11 supports typed metadata lookup for JSON serialization. It provides type-safe access to resolve JsonTypeInfo<T> during serialization and deserialization, moving away from exception-driven access patterns.

When should I use TryGetTypeInfo<T> instead of GetTypeInfo<T> for JSON metadata?▼

Use JsonSerializerOptions.TryGetTypeInfo<T>(out ...) when you need to check whether type metadata is available without throwing exceptions. GetTypeInfo<T>() is better when you require the metadata and expect the type to be registered.

What is the best way to access System.Text.Json metadata in a type-safe way?▼

The best way to access System.Text.Json metadata safely is using typed metadata retrieval APIs like GetTypeInfo<T>(). This resolves the problem of untyped metadata access and exception-driven checks during .NET 11 JSON serialization.
