HttpClient BaseAddress

When using HttpClient class in .NET, I found out when assigning the BaseAddress to HttpClient, the BaseAddress must end with "/". Otherwise it would get 404 error when calling the get or post method.
 
using (var client = new HttpClient())
{
 client.BaseAddress = new Uri("http://localhost/");
 client.DefaultRequestHeaders.Accept.Clear();
 client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

 HttpResponseMessage response = await client.GetAsync("Setting");
 if (response.IsSuccessStatusCode)
 {
  return await response.Content.ReadAsStringAsync();
 }
 else
 {
  ilog.Error(string.Format("GetGlobalSetting error - StatusCode: {0};  ReasonPhrase: {1} ", response.StatusCode.ToString(), response.ReasonPhrase??""));
  throw new Exception(string.Format("Error getting Global settings - StatusCode: {0};  ReasonPhrase: {1}", response.StatusCode.ToString(), response.ReasonPhrase ?? ""));
 }
}
