In LinqPad simple query the Customer as I have pictured above with a Guid and LinqPad will generate the Url it is using for you.
Pseudo sample code for LinqPad:
var myId = new Guid("5C60F693-BEF5-E011-A485-80EE7300C695");
Customer.Where(c => c.CustomerId == myId);
Click on the Request Log as pictured above and you will see the correct syntax.
