Hi,

I started working my way through the book without any problem when suddenly I started getting the error below upon doing CTRL F5:

Failed to start ASP.NET development server on Port: 1109
Error: Only one usage of each socket address is normally permitted.

The error above is followed by

Unable to connect to the configured Web server.

Hi there,

This error is new for me. It looks like that specific port is already taken. You can choose a new port by looking at the Properties Grid for the project (click the project in the Solution Explorer and hit F4).

Hope this helps,

Imar
