    <h2>Edit 1</h2> <p>I am confused with the statement below, taken from <a href="http://odetocode.com/articles/305.aspx" rel="nofollow noreferrer">What ASP.NET Programmers Should Know About Application Domains </a>:</p> <blockquote> <p>You’ve created two ASP.NET applications on the same server, and have not done any special configuration. What is happening?</p> <p>A single ASP.NET worker process will host both of the ASP.NET applications. On Windows XP and Windows 2000 this process is named aspnet_wp.exe, and the process runs under the security context of the local ASPNET account. On Windows 2003 the worker process has the name w3wp.exe and runs under the NETWORK SERVICE account by default.</p> </blockquote> <p>He said that there is one worker process spawns 2 application domains--one application domain for each asp.net application.</p> <p>But when I see the running processes as follows, </p> <p><strong>Image 1</strong></p> <p><img src="https://i.stack.imgur.com/qnBL7.png" alt="enter image description here"></p> <p><strong>Image 2</strong></p> <p><img src="https://i.stack.imgur.com/TiMJ0.png" alt="enter image description here"></p> <p><code>w3wp.exe</code> is said as IIS Worker Process rather than application pool or application domain.</p> <h2>Questions:</h2> <ol> <li>Is application domain equal to application pool?</li> <li>The confusing thing is in image 1. Why does <code>Host Process Windows Service svchost.exe</code> spawns 2 <code>IIS Worker Process w3wp.exe</code>? In my understanding, a process can only contain application domains, not other processes.</li> </ol>

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.
