dotnet-source-gen-json

Configure System.Text.Json source generation for AOT-compatible, reflection-free JSON serialization with compile-time type metadata.

When to Use

• Preparing application for Native AOT compilation
• Eliminating reflection-based serialization overhead
• Improving startup performance by generating serialization code at compile time
• Ensuring JSON serialization errors surface at compile time

Requirements

• .NET 8 or higher for full options support
• .NET 6+ for basic source generation

Steps

1. Invoke polymorphic skill first:
   • Run dotnet-json-polymorphic skill to ensure polymorphic types are configured
   • This ensures [JsonDerivedType] attributes are in place before generating context
