The URI prefix is not recognized.

I have downloaded the latest code & just tried to run the project "mpost.SilverlightMultiFileUpload" in VS 2010 with Silverlight 4.0 installed in it. It is giving error "The URI prefix is not recognized." while uploading file in following line

 HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(httpHandlerUrlBuilder.Uri);

in class HttpFileUploader : IFileUploader



 Can you please help me, I am stuck..

Many Thanks.

Hi, lovely control... Good work.

I'm trying to embed this into my silverlight 4 application, I convert it to .Net4 & Silverlight 4... Works on my Dev machine but not under IIS (with correct App Pools) with ReadHttpCallBackResponce errors. So I took it back to .net3.5 and SL3 with correct app pool and it works, under IIS. Is there something I am missing?

The Silverlight control is already Silverlight 4. Silverlight runs on the client so that can't be the problem.

Maybe your HttpHandler that receives the files is not working properly? Try debugging it.
