title: Debug using attach to process of windows installer
body: <p>I have my <em>.msi</em> windows installer project with multiple services to install. I have a <code>NullReferenceException</code> during installation and I would like to debug installation process to figure out what is going on. I tried <strong>Debug > attach to process</strong> but it didn't hit any breakpoint. <code>Debugger.Break()</code> didn't help me as well. Can somebody explain how to solve this problem?</p>
