(413) Request Entity Too Large
As we know by default the limit to send data to our WCF Service is 4mb. But when we try to transfer the data more than 4mb it throws the exception something like that The remote server returned an unexpected response: (413) Request Entity Too Large.
To fix this exception you have to increase the size of WCF Service call to maximun size in web service Web Config file.
Please add the following image code in your WCF Config file.
