我正在尝试将 Windows Azure 站点从云降级为网站。我收到此错误：

因为我不在云端，我需要这个程序集吗？我如何告诉网站不要寻找它？我已将这些引用添加到我的项目中：
Microsoft.WindowsAzure.CloudDrive Microsoft.WindowsAzure.Diagnostics Microsoft.WindowsAzure.ServiceRuntime Microsoft.WindowsAzure.StorageClient
在我的 WorkerRole.cs 类中，这是我的代码：
/// <summary>
/// Reads settings from service configuration file.
/// </summary>
/// <param name="key">Setting key.</param>
string AzureHelper_GetApplicationSettings(string key)
{
try
{
return RoleEnvironment.GetConfigurationSettingValue(key);
}
catch
{
// Setting key was not found
return null;
}
}
