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

I just faced this right now...

Here on my end, I have 2 separated Visual Studio solutions (.sln)... opened each one in their own Visual Studio instance.

Solution 2 calls Solution 1 code. The problem was related to the port assigned to Solution 1. I had to change the port on solution 1 to another one and then Solution 2 started working again. So make sure you check the port assigned to your project.
