When we added a WCF service reference to the client, the information was as follows

An error occurred while downloading "Http://localhost:8001/WCFService".

If the service is defined in the current solution, try building the solution and adding the service reference again.

Solution:

1. View firewall settings. Do you have a service port open, such as 8001, if not, add a service port as a secure port;

2. Check that the service managed process is started, typically running service hosting programs for custom hosts to host services.

Re-add the WCF service reference. will be successful.
