What problem does it solve?

This Skill streamlines the creation of System.Text.Json source generation for AOT-friendly JSON serialization, reducing runtime reflection and improving startup performance.

Core Features & Use Cases

  • Generate a JsonSerializerContext: automatically creates a {ProjectName}JsonContext class with JsonSerializable types.
  • ASP.NET Core integration: configures HttpJsonOptions to use the generated context for type resolution.
  • Reduce reflection overhead: enables compile-time generation of serialization code for faster startup.

Quick Start

  • Run the dotnet-json-polymorphic skill to prepare polymorphic types for source generation.
  • Identify the target project (ASP.NET Core or library) and ensure .NET 8+ is installed.
  • Allow the skill to create {ProjectName}JsonContext.cs and update Program.cs to hook MyApiJsonContext.Default into the JSON options.
