When connecting to a WCF project in the same solution (hosted in IIS) I get this 415 error (Silverlight reports as a 404, but Fiddler tells the truth)

HTTP/1.1 415 Cannot process the message because the content type 'text/xml; charset=utf-8' was not the expected type 'application/soap+xml; charset=utf-8'.

Is this expected, and how might it be caused? I'm using a basicHttpBinding and endpoint that's pointing at my machine with a name instead of localhost.

Problem with byte order mark:

Using Fiddler to debug the communication between Silverlight 2 and my Oracle server I've managed to nail the problem:

Silverlight 2 proxy adds a byte-order-mark when creating the UTF-8 SOAP message. This is caousing the Oracle XML parser to fail.

Is there a way to plug into the Silverlight WCF pipeline to pervent it from adding the BOM to the request?

Got it working:

BasicHttpBinding binding = new BasicHttpBinding();

binding.TextEncoding = new UTF8Encoding(false);

EndpointAddress address = new EndpointAddress("youServiceUrl");

serviceClient = new GetNewsClient(binding, address);

The problem is the default UTF8Encoding constructor will make it emit the BOM. You can change this by setting the TextEncoding of the binding to a new UTF8Encoding object, where you pass in false in the constructor to make it NOT emit the BOM when serializing the request.

Hi Eugene, I've read your post and it's really one of the best I've seen early in the net. But even according all your recomendations it's still a problem to get my services work with my silverlight application.

The issue is ProtocolException error I'm getting when calling the service. At first I have ran a WebDevelopment Helper and it showed me the first problem you talking about - Hi Eugene, I've read your post and it's really one of the best I've seen early in the net.

The issue is ProtocolException error I'm getting when calling the service.

I have tried to fix it with different variations from the net... At first I have ran a WebDevelopment Helper and it showed me the first problem you talking

about - it was Cross-Domain Issue and there were no files like clientaccesspolicy.xml or crossdomain.xml. So WebDevelopment Helper showed me 404 response for

these two files. I have created these files and put into a root catalog. This solved the 404 error in WebDevelopment Helper. And now it shows 200. So seems

to be ok. But now when I running my SL application and it calls to webservice it show me "The remote server returned an unexpected response: (404) Not Found." ProtocolException was unhandled by user code. I have checked all situations from the net that may be the reason of this issue, cheked web.config, ServiceReferences.ClientConfig, clientaccesspolicy.xml and crossdomain.xml files but nothing helps... Now I really do not know how to get it work. Could you please help me in this issue? Any suggestions will be appreciated. Thanks in advance!!!

I was testing out some typography with Silverlight and figured I’d try grab some text from Wikipedia
