+### 📁 File Upload with IFileContent
+
+For file uploads via `WithBody()`, implement the `IFileContent` interface:
+
+```csharp
+using Atc.Rest.Client;
+
+public class MyFile : IFileContent
+{
+    public string FileName { get; init; }
+    public string? ContentType { get; init; }
+    public Stream OpenReadStream() => File.OpenRead(path);
+}
+
+var requestBuilder = messageFactory.FromTemplate("/api/files/upload");
+requestBuilder.WithBody(new MyFile { FileName = "report.pdf", ContentType = "application/pdf" });
+
+using var request = requestBuilder.Build(HttpMethod.Post);
+using var response = await client.SendAsync(request, cancellationToken);
+```
+
+`WithBody()` also accepts `List<IFileContent>` for multi-file uploads.
+
+> **Platform compatibility:** `WithBody()` automatically detects file-like objects that have
+> a `FileName` (or `Name`) property and an `OpenReadStream()` method. This means ASP.NET Core

+> public async Task<IActionResult> Upload(IFormFile file)
+> {
+>     requestBuilder.WithBody(file);

+> // Blazor WASM component - works automatically
+> private async Task OnFileSelected(InputFileChangeEventArgs e)
+> {
+>     requestBuilder.WithBody(e.File);
+> }
+> ```
+>
+> For compile-time type safety, implement `IFileContent` explicitly.
