Converting Remoting to WCF

Question

I have converted my remoting service to WCF. 

 

I unable to access server methods from client & getting below error:

 

Could not connect to net.tcp://localhost:8000/UserManagement. The connection attempt lasted for a time span of 00:00:00.9997717. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000. 

 

 

 

Please help me to come out.
