    <p>Hi guys I created a service using WCF but when I test my services some completed successfully why some is giving me the error below. Any Idea on how to solve these ? Thanks</p> <pre><code>An error occurred while receiving the HTTP response to http://localhost:8733/PortOperation/Operator_Service/ws. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

    2. COYes, when that method is called it goes to my data layer to get the data, I don't know why the error because two of my services are working

    3. CODid you try running only this test without the other two? It looks like you might be opening too many connects in your tests without closing them, see the InnerException in your original post. I would try this and if it works, it's not the code per se, but likely the battery of tests running at once and not closing connections.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
