 <ParamField path="use-discriminated-unions" type="boolean" required={false} toc={true}>
 When enabled, generates discriminated union types for API responses that can contain multiple different object types. This provides type-safe handling of polymorphic responses.

+When enabled, the generated SDK sends a `User-Agent: <NuGetPackageId>/<version>` header on every request when the API definition does not specify an explicit `User-Agent`. This mirrors other generators' `<package-name>/<version>` fallback.
+
+The prefix is taken from the cascade `package-id` → `namespace` → `PascalCase(<organization>_<api-name>)`, so it matches whatever name the SDK ships under on NuGet. Defaults to `false`.
