Calling into my own DLL when depolyed on Azure - azure

Question

I have a simple Windows Azure cloud service that does random number generation running on my local machine. I have then published this to azure
public string GetNumber()
{
Random number = new Random();
return "number = " + number.Next(1, 100).ToString() + " number ";
}
When I call this method from my client everything works fine.
ie
ServiceReference1.RandomNumbersClient client = new ServiceReference1.RandomNumbersClient();
Console.WriteLine("Starting .... ");
Console.WriteLine(client.GetNumber());
Now, the next step is I have added some code that requires "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5.2\System.Speech.dll" to be available in the project. This is easy on my local server as I just add the reference to the dll in my VS project.
New method ....
public string GetNumberAsString()
{
Random number = new Random();
SpeechSynthesizer synth = new SpeechSynthesizer();
synth.SetOutputToDefaultAudioDevice();
synth.Speak("This example demonstrates a basic use of Speech Synthesizer");
return "number = " + number.Next(1, 100).ToString() + " number ";
}
Problem now is when I publish to Azure. How do I make the DLL available to my app running in Azure?
When I call the GetNumber() method it works fine but any call to GetNumberAsString() fails because of the additional code.
ServiceReference1.RandomNumbersClient client = new ServiceReference1.RandomNumbersClient();
Console.WriteLine("Starting .... ");
Console.WriteLine(client.GetNumberAsString());
How do I actually inspect the logs for the Webservice running on Azure so I can make a start at finding out what the problem is.
