**Kind:** Service

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

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

NuGet package dependency

`System.Net.Http.Primitives` is a NuGet dependency declared by the `Pams.Email` project. It provides legacy .NET HTTP primitive types that email-related code can reference when handling HTTP methods, headers, requests, or responses.

## Diagram

    participant Client
    participant EmailApi as Pams.Email API
    participant HttpPrimitives as System.Net.Http.Primitives

    Client->>EmailApi: Send HTTP request
    EmailApi->>HttpPrimitives: Read HTTP method and headers
    HttpPrimitives-->>EmailApi: HTTP primitive values
    EmailApi-->>Client: Return HTTP response
```

## Usage

```ts
async function sendEmailRequest() {
  const response = await fetch("/api/email/send", {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
    },
    body: JSON.stringify({
      to: "user@example.com",
      subject: "Status update",
      body: "Your request has been received.",
    }),
  });

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

  return response.json();
}
```

## AI Coding Instructions

- Treat this package as a .NET project dependency; do not import it directly from TypeScript or browser code.
- Keep HTTP request and response handling in the `Pams.Email` server-side integration layer.
- Check existing package references before replacing this legacy-format dependency with newer HTTP libraries.
- Preserve current HTTP header and method behavior when changing code that references types from this package.
