I am tying to get the generic List of user List<User> object from my web service to my web application. probably this is common issue. i searched a lot but got different remedies with each link. so finally i decide to ask to chaps over here... anyways
I am using console application for fetching the data from my hosted wcf web service. where as my WCf web service having the Entity framework 4.1. am using objects from its model class. when i tried to add service reference to my web application , it typically generates the proxy in web app. i am able to post data means i could create user. but while getusers which is returning List , getting following exceptions...:
Exception:
An error occurred while receiving the HTTP response to http://myserver/AdminService/MyAdminService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.Inner Exception is :
The underlying connection was closed: An unexpected error occurred on a receiveand inner-inner exception is : Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
with message : An existing connection was forcibly closed by the remote host
Error Code :10054Where as Event log saying :

What should be this issue. me and team searching for this since 3 days. but unfortunately not overcome so far...
I tried lot of stuffs like add serializable attribute, endpoint modifications ... i can not recollect all :) ... probably you may give us right directions...
