Answer
Content negotiation selects the response format based on:
- Client's Accept header
- Configured formatters (JSON, XML)
ASP.NET Core defaults to JSON.
Quick Answer
Content Negotiation lets the client specify what format it wants (JSON, XML) via the Accept header. The server checks available output formatters and picks the best match. ASP.NET Core includes JSON formatter by default. Add XML: services.AddControllers().AddXmlSerializerFormatters(). If no match: returns default format (406 Not Acceptable if configured strictly).
