WCF : System.Net.Sockets.SocketException (0x80004005): An existing connection was forcibly closed by the remote host

WCF : System.Net.Sockets.SocketException (0x80004005): An existing connection was forcibly closed by the remote host

Exception:  'System.Net.Sockets.SocketException (0x80004005): An existing connection was forcibly closed by the remote host'

I  recently encountered WCF socketException and found that there could be majorly two reasons for this issue

• Service Proxy was ideal for almost 10 minutes and after we can try to use the same service proxy.
• Service is slowness, in this case, Service response time is crossed the default value of receiving timeout 

Considering the above two points, I made following changes in service config file, after that refreshed the client proxy with latest settings

1.       Increased the ReceivingTimeout   value to infinity

       <binding name="netTCPBinding"   receiveTimeout= "infinite" >

2.       Increased the inactivityTimeout value to infinity in reliable session setting

<reliableSession inactivityTimeout="infinite" enabled="true" />
