[IronPython] Calling WCF service

Hi,

We are using channel Factory for calling WCF service in ironpython. But when
we give call to a method in that service, the method is not called and it
shows CPU usage almost 100%.
This method takes the request object and returns response.


I am giving the code snippet here.


This is in config file

 

<client>
<endpoint address="net.tcp://127.0.0.1:9083/MessagingService/"
binding="netTcpBinding" bindingConfiguration="BusinessNetTCPBinding"
contract="OnlineAVL.Services.Messaging.Interface.IOnlineAVLMessagingService"
name="MessagingServiceEP" />
</client>


in program.py

import clr



clr.AddReference('System.ServiceModel')
clr.AddReference('System')



import System
import System.ServiceModel



from System.ServiceModel import *



clr.AddReferenceByPartialName('OnlineAVL.Services.Messaging.Interface.dll')

from OnlineAVL.Services.Messaging.Interface import *



_factory = ChannelFactory[IOnlineAVLMessagingService]("MessagingServiceEP")
service = _factory.CreateChannel();


# request object is populated here
req = Request();
req.ID=System.Guid.Empty
req.Version=0

print "calling"
#call to method
res=service.GetPeriodMessagesByOwner(req)

print res


When we execute this, on console it prints "calling" and after that CPU
usage goes up to 100%, and the machine becomes extremely slow and then gives
OutOfMemory Exception. It does not call the service method also.
Any solution to this problem?
Thanks in advance.
