I am trying to prototype a Rpc Call to a JBOSS webserver from Silverlight (4). I have written the code and it is working in a console application - so I know that Jboss is responding to the web request. Porting it to silverlight 4, is causing issues:

let uri =  new Uri(queryUrl)

// this is the line that hangs
let request : HttpWebRequest = downcast WebRequest.Create(uri)

request.Method <- httpMethod;

request.ContentType <- contentType

It may be a sandbox issue, as my silverlight is being served off of my file system and the Uri is a reference to the localhost - though I am not even getting an exception. Thoughts?

Thx

UPDATE 1

I created a new project and ported my code over and now it is working; something must be unstable w/ regard to the F# Silverlight integration still. Still would appreciate thoughts on debugging the "hanging" web create in the old model...

let uri = Uri("http://localhost./portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas")

// this WebRequest.Create works fine
let req : HttpWebRequest = downcast WebRequest.Create(uri)

let Login = async {
    let uri =  new Uri("http://localhost/portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas")

     // code hangs on this WebRequest.Create
     let request : HttpWebRequest = downcast WebRequest.Create(uri)

     return request
}

Login |> Async.RunSynchronously

I must be missing something; the Async block works fine in the console app - is it not allowed in the Silverlight App?
