**Source:** `Pams/Logic/Pams.Business/Pams.Business.csproj` (line 1)

**Part of:** [Pams](subsystem-pams)

NuGet package dependency

`System.Runtime.Serialization` is a NuGet package dependency referenced by `Pams.Business`. It supports serialization contracts and legacy-format data handling within business-layer code that exchanges serialized payloads with other system components.

## Usage

```ts
type SerializedRecord = {
  id: string;
  status: string;
};

async function loadRecord(id: string): Promise<SerializedRecord> {
  const response = await fetch(`/api/records/${encodeURIComponent(id)}`);

  if (!response.ok) {
    throw new Error(`Record request failed: ${response.status}`);
  }

  return response.json();
}

const record = await loadRecord("record-id");
console.log(record.status);
```

## AI Coding Instructions

- Treat `System.Runtime.Serialization` as a package dependency of `Pams.Business`, not as a JavaScript runtime package.
- Keep serialized contract names and field shapes compatible with existing business-layer models.
- Check for legacy-format serialization attributes before changing model properties or constructors.
- Update the project dependency configuration when adding code that requires serialization APIs.
