Error sending large byte array

Question

I have WCF service through which I am adding data in DB. It works fine, but when I try to send large byte[] it returns "remote server returned an error: NotFound".

Answer 1

The 404/Not Found is the error Silverlight reports for all server errors. If you want to know the actual error being returned from the server you can use something like Fiddler to view what is being sent and received, including the headers which contain the actual error code and error message returned by the server.

Answer 2

I think you should apply the same

<readerQuotas ...

On the client.
