No connection could be made because the target machine actively refused it?

Question

Sometimes I get the following error while I was doing HttpWebRequest to a WebService. I copied my code below too.

System.Net.WebException: Unable to connect         


        

Answer 1

In my scenario, I have two applications:

• App1
• App2

Assumption: App1 should listen to App2's activities on Port 5000

Error: Starting App1 and trying to listen, to a nonexistent ghost town, produces the error

Solution: Start App2 first, then try to listen using App1
