    <p>I could have sworn that I've used NUnit's Assert.Throws to determine whether or not a particular exception gets thrown from a method, but <a href="https://stackoverflow.com/questions/2388827/can-anyone-explain-why-dictionary-in-c-doesnt-work-like-mapt-u-in-stl">my memory has failed me before</a>. I read <a href="https://stackoverflow.com/questions/1609536/nunit-assert-throws">this post here on SO</a>, but it didn't answer my question, as I know the correct syntax, and I don't want to do anything with the exception that gets returned (I don't want to look at the Exception's members, though this could be useful down the road).</p> <p>I wrote unit tests to prove my lack of understanding in the use of Dictionary, and couldn't get it handle the KeyNotFoundException that gets thrown. Instead of NUnit catching it and passing the test, I get an unhandled KeyNotFoundException error when I run. I verified that I don't have the VS IDE set up to break on thrown .NET exceptions.</p> <p>I've tried this two ways:</p> <pre><code>Assert.Throws( typeof(KeyNotFoundException), () =&gt; value = prefs["doesn't exist"]); </code></pre> <p>and</p> <pre><code>Assert.Throws&lt;KeyNotFoundException&gt;( () =&gt; value = prefs["doesn't exist"]); </code></pre> <p>but both result in an unhandled exception. What am I missing here?</p> <p><strong>UPDATE</strong> seems like others can't reproduce this. Here's a screenshot:</p> <p><a href="http://i47.tinypic.com/2qs2hhz.jpg" rel="nofollow noreferrer">alt text http://i47.tinypic.com/2qs2hhz.jpg</a></p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
