Resolve WCF "This may be due to a service endpoint binding not using the HTTP protocol, which may also be caused by the server aborting the HTTP request context (possibly due to service shutdown)" exception

Recently, the architecture of the system has been optimized to invoke WCF with the WinForm impersonation client, a bus from WCF that pushes the received message to each sub side.

It would have been simple to invoke the relationship, and after the WCF service was deployed to IIS, it had been reported that an error occurred while receiving the HTTP response to Http://lenovo-y460:8099/Service.svc. This may be due to the fact that the service endpoint bindings are not using the HTTP protocol. This may also be caused by the server aborting the HTTP request context (possibly due to a service shutdown). For more information, see Server logs. "Exception, as shown in the effect:

Exception, the exception is excluded by the control variable method.

The elimination process is as follows:

1. The Publish method invocation of the ESB, which is invoked by the client in the WCF debug state, proves that the push of the ESB is not a problem;

2. Use WinForm to invoke the test method of WCF deployed on IIS (does not include bus. Publish method) invocation succeeds, proving that the WCF service is no problem;

3. Calling the Bus.publish method call of WCF deployed on IIS with WinForm fails to report the above exception;

4. Invoke the bus in WCF debug state with WinForm . The Publish method call succeeded.

The final result (degree Niang said what class is not serialized, mercilessly put me in the hole): it is probably the cause of IIS.

Since WinForm can invoke the WSDL address in WCF Debug state, why can't I invoke the WSDL address that WCF deploys on IIS? Most likely because IIS has insufficient permissions, the solution is as follows:

IIS Manager--Application pool--Select target app pool--Advanced settings--process model----and custom account----Input native Administrator level user name, password, The configuration is as follows:

This bug was tuned for 3 days, and today it's settled, and it's a very fulfilling feeling.

I hope that my explanation can help you to improve.
