Creating a hosted service and dealing with the “Bad Request”

In several situations when working with the Azure Management API, I’ve found that the exception containing the message “The remote server returned an unexpected response: (400) Bad Request.” is not really useful. I’m using the NuGet package (Windows Azure Service Management Library Nuget Package) to communicate with the Azure Management REST API.
I’ve found the solution in the WCF ProtocolException receiving html

public void CreateHostedService(string name, string azureLocation)
        var createHostedServiceInput = new CreateHostedServiceInput
                Label = ServiceManagementHelper.EncodeToBase64String(name),
                ServiceName = name,
                Location = azureLocation

        Channel.CreateHostedService(SubscriptionId, createHostedServiceInput);
    catch (ProtocolException e)
        throw CreateUsableException(e);

private static Exception CreateUsableException(ProtocolException protocolException)
    var webException = protocolException.InnerException as WebException;
    if (webException != null && webException.Response != null)
        var responseStream = webException.Response.GetResponseStream() as MemoryStream;
        if (responseStream != null)
            var responseBytes = responseStream.ToArray();
            var responseString = Encoding.UTF8.GetString(responseBytes);
            return new Exception(responseString);

    return new Exception("No return message could be extracted from the exception!");
