## 🎯 Implementation Highlights

### Fluent API Consistency
```csharp
server
    .Given(Request.Create().WithPath("/ws"))
    .RespondWith(Response.Create().WithWebSocketHandler(...))
```

### Multiple Handler Options
```csharp
// Option 1: Full context
.WithWebSocketHandler(async ctx => { /* full control */ })

// Option 2: Simple WebSocket
.WithWebSocketHandler(async ws => { /* just ws */ })

// Option 3: Message routing
.WithWebSocketMessageHandler(async msg => { /* routing */ })
```

### Zero Dependencies
- Uses only .NET Framework APIs
- No external NuGet packages
- Clean architecture

## 🎓 Usage Example

```csharp
// Start server
var server = WireMockServer.Start();

// Configure WebSocket
server
    .Given(Request.Create().WithPath("/ws"))
    .RespondWith(Response.Create()
        .WithWebSocketHandler(async ctx =>
        {
            var buffer = new byte[1024 * 4];
            while (ctx.WebSocket.State == WebSocketState.Open)
            {
                var result = await ctx.WebSocket.ReceiveAsync(
                    new ArraySegment<byte>(buffer),
                    CancellationToken.None);
                
                await ctx.WebSocket.SendAsync(
                    new ArraySegment<byte>(buffer, 0, result.Count),
                    result.MessageType,
                    result.EndOfMessage,
                    CancellationToken.None);
            }
        })
    );

// Use it
using var client = new ClientWebSocket();
await client.ConnectAsync(new Uri($"ws://localhost:{server.Port}/ws"), CancellationToken.None);
// ... send/receive messages ...
```
