使用WCF Web服务时“没有侦听端点可以接受消息”

Question

I've seen several questions about this, but they all seem to be from the perspective of someone hosting a web service. In my case, I am the consumer only to a web service being provided by another company that I don't have access/control over.

Basically the other company is hosting a WCF web service that has two methods that I need to call. I added the service reference to ac# console application using the URL/WSDL and it generated the necessary classes. So far, so good.

But when I call either of the methods via my app, it comes back with a "There was no endpoint listening at that could accept the message" and the inner exception says "The remote server returned an error: (404) Not Found."

When I checked the WSDL, I noticed there is no 'bindings' section and indeed no binding details have been automatically generated in my app.config. When I've consumed web services in the past, I've never had to worry about this part, so I'm not sure if it's normal.

So, my question is: Is this an error on the other companies part and do they have to provide this information to me, or is this something I should be able to configure from my end?

Answer 1

IIS server, hosting WCF service, filter incoming requests against some criteria's and reject request with a 404 Not found error page if some validation fail.

For example IIS will reject request with 404 not found page if request size is more than ~28.6MB (default value) or configured limit ( reference ).

You can check your call against some of the default limits and then can ask company for more details.
