c# - An unsecured or incorrectly secured fault was received from the other party -

I have a Windows program called WCF service. After some time this service is slow and in the end This error will be encountered. Restart once again after starting the service. with honesty.

You probably are not closing the connection to the WCF service.

WCF has 10 connections default and one minute expiration.

What happens next is that the first 10 hits got cured, the 11th has to wait for an available connection, after one minute when the time of 1 connection is over.

Therefore the solution is to ensure that you are closing the WCF connection
