    <p>I enjoy and highly recommend <a href="http://www.idesign.net" rel="nofollow noreferrer">Juval Lowy's</a> - <a href="http://www.idesign.net/Downloads/GetDownload/1985" rel="nofollow noreferrer">C# Coding Standard</a>. Juval explicitly avoids rationale for each directive in order to keep the standard tight (see the preface). However, there are a few directives for which I find myself curious as to the rationale. </p> <p><strong>What is the specific rationale to the following directives from Lowy's C# standard?</strong><br> Hopefully there are hard (non-subjective) answers to these. </p> <p><strong><em>1.13 Avoid fully qualified type names. Use the "using" statement instead.</em></strong><br> Is this a performance issue? Sometimes I only need one instance of the fully qualified name and adding a <em>using</em> seems heavy.</p> <p><strong><em>1.26 Use empty parenthesis on parameterless-anonymous methods. Omit the parenthesis only if the anonymous method could have been used on any delegate.</em></strong><br> Actually I am just confused by the second sentence. Explanation with example(s) would help, thank you.</p> <p><strong><em>2.19 Avoid defining custom exception classes</em></strong><br> What are the considerations in minimizing their numbers? (He next gives guidelines if you do define them (in 2.20).)</p> <p><strong><em>2.29 Avoid using the ternary conditional operator</em></strong><br> Too hard for the reader to digest, or other considerations?</p> <p><strong><em>2.31 Avoid function calls in Boolean conditional statements. Assign into local variables and check on them.</em></strong><br> I don't think I do this, but I am curious...why not?</p> <p><strong><em>2.47 Avoid interfaces with one member.</em></strong><br> Because it is always/usually more prefereable to do what? One method interfaces work when?</p> <p><strong><em>2.53 Prefer using explicit interface implementation</em></strong><br> Why? Also, <a href="https://stackoverflow.com/questions/408415/why-explicit-interface-implementation">Jon Skeet disagrees here</a>.</p> <p>Thanks in advance! Robert</p>

    1. COI think this should be community wiki, as it will be a lot of single answers, and there is no 'correct' answer unless Juval himself pipes up.

    2. COI think SO experts might actually "know" the answers. Do I really need to break it up into 7 questions? I keep getting bitten by the community wiki bug, very frustrating.

    3. CORe: 7 questions. I'd say yes. Thus far no one has responded to all points and, frankly, why I haven't chimed in.

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).
