Does anyone have experience with or information about using CUPI in a .NET environment? 
 
I know AXL for CUCM requires a proxy class to work in .NET.
 
Most helpful would be an example of connecting to CUPI and performing basic operations in C#.NET.
 
Thanks,

I was able to get the GET method to return all CUC users using C#.NET and following the examples you posted.  I just had to add credentials and invoke ServerCertificateValidationCallback to get around validation of the local cert on the CUC box.
 
But when I try to add or update a user following the examples in the wiki on this site, CUPI returns "<405> Method Not Allowed".  "Protocol Error".  I tried confirming the method and parameter names in the WADL, and both seem to match up.  I tried calling the CUPI methods using both HttpWebRequest and WebClient classes in C#.NET with no success.
 
Any ideas?

Thanks, Matt.
 
I got it working by forcing basic authentication in the message header as follows:
 
byte[] authorizationHeaderBytes = System.Text.Encoding.UTF8.GetBytes("<user>" + ":" + "<password>");
string authHeader = "Basic " + Convert.ToBase64String(authorizationHeaderBytes);
client.Headers.Add("Authorization", authHeader);
 
The above code replaces the previous authentication line:
client.Credentials = new System.Net.NetworkCredential("<user>", "<password>");
 
The next challenge is to enable and add an address to the SMTP notificaiton device type for each user.  Users created with CUPI in my testing have an SMTP notification type already that is disabled.  Maybe this comes from the template?
 
Could you post an example of updating a user's SMTP notification device to set "Active" to true and write to the "SmtpAddress" value?
