```csharp
try
{
    // Attempt to connect to a non-existent server
    WmClient client = WmClient.Create("http", "invalid-host", "9999", "");

    JSONDeviceData device = client.LookupUserAgent("Mozilla/5.0");
    Console.WriteLine("Device: " + device.Capabilities["brand_name"]);
}
catch (WmException e)
{
    // Handle WURFL-specific errors
    Console.WriteLine("WURFL Error: " + e.Message);

    // Check for inner exception (network, HTTP, etc.)
    if (e.InnerException != null)
    {
        Console.WriteLine("Caused by: " + e.InnerException.GetType().Name);
        Console.WriteLine("Details: " + e.InnerException.Message);
    }
}

// Example: Handling invalid manufacturer lookup
WmClient validClient = null;
try
{
    validClient = WmClient.Create("http", "localhost", "8080", "");

    // This will throw WmException if manufacturer doesn't exist
    JSONModelMktName[] devices = validClient.GetAllDevicesForMake("NonExistentBrand");
}
catch (WmException e)
