Answer 1

Hello, Silverlight doesn't support WS2007HttpRelayBinding. It doesn't even support BasicHttpRelayBinding. However, you can use BasicHttpRelayBinding on the service side, and turn off ACS, so it will have the same behavior as BasicHttpBinding. On the client side, you can just use a BasicHttpBinding to access the service.

Hi Thanks for your reply.

I have tried with basicHttpRelaybinding  but i was getting the same error.

this error is not happening for every method, it is only coming for some methods in the service, where we were using entity frame work to get the data .

 

Answer 3

Try to use Fiddler to monitor the response. Does the response contain a correct xml representation of the entity?

Hi ,

No the xml response is breaking after some point.on premaise  i am getting  the complete response without any issues.

But i f i use servciebus end point i am getting this error,

Onpremise we were using </binarymessageencoding> in the custome  binding. but in any  of the basicHttpRelaybinding,wsrelayBinding,webhttpRelayBinding ,the same was not supporting .

Is there anything we can do to get the complete xml message without getting deserialization error.

Thanks !

Answer 5

Yes. Service Bus is incompatible with Silverlight's binary message encoding. You have to use text encoding.

Answer 6

Hi thanks for your responses. so by default is using text encoding.

Can we do anything in  service or client configurations to get the complete data with out de serialization error ?

or

do we need to  change anything from code side ?

Please suggest me any solution about this issue?

Thanks !

Answer 7

Are you using text encoding or binary encoding now? If you use text encoding, you should not have deserialization problem. If you use binary encoding, then you have to switch to text encoding.
