Now my issue is i am unable to generate proxy through net.tcp binding but i can generate it through http. http://testsrv.com/RewindService/RewindTest.xamlx?wsdl. then i am unable to call receive operation method. Although it is workking fine with local console Host.

Answer 1

As we know that workflow service is similar to wcf service. So I decided to reconsider my deployment steps. I found a very good link about it and follow and check each and every step carefully and able to resolved my problem.

My configuration is ok and updated the tcp port no. it works like a charm.
