Hi drl,
When I hit the Validate Connection button, I get the error that "Invalid URI, the hostname
could not be parsed".
Can anyone help?
According to your publish setting and error message, I guess you type the wrong message when you create the publish profile.
Since I don't know how you set your IIS and your IIS website application name, I create a test WCF application and publish it to IIS.
I suggest you could refer to my publish step:
1.Create a IIS web site:

Remember the site name and port.
2.Publish the application:

Best Regards,
