    <p>This post is in continuation of <a href="https://stackoverflow.com/questions/1842636/why-cannot-c-generics-derive-from-one-of-the-generic-type-parameters-like-they-c">this one</a>.</p> <p>I am trying to understand if I am the only one who misses and needs the ability of a .NET generic type to inherit one of its generic parameter types.</p> <p>The challenge is to collect compelling reasons in favour of this feature or, alternatively, get to know that there are none.</p> <p>I give my reason to have it as an answer to this question - see below.</p> <p>I am asking folks out there to add theirs as answers to this post.</p> <p>If you disagree that the feature is useful or have no good reasons in favour - please refrain from posting anything here, though you can do so in the original post that has started it all - <a href="https://stackoverflow.com/questions/1842636/why-cannot-c-generics-derive-from-one-of-the-generic-type-parameters-like-they-c">here</a>.</p> <p><strong>P.S.</strong></p> <p>Some C++ patterns are irrelevant in .NET. For instance, in his excellent book <a href="http://rads.stackoverflow.com/amzn/click/0201704315" rel="nofollow noreferrer">Modern C++ Design</a> Andrei Alexandrescu describes how to create a list of types evaluated at the compile time. Naturally, this pattern is irrelevant for .NET, where if I need a list of types I just create <code>List&lt;Type&gt;</code> and populate it with types. So, let us try to come up with reasons pertinent to the .NET framework and not just blindly translating C++ coding techniques to C#.</p> <p><strong>P.P.S.</strong></p> <p>Of course, this discussion is strictly academic. Even if a hundred compelling reasons for the feature in question is surfaced it is not going to be implemented, ever.</p>

    1. COIs it me or does this seem like a new approach to the same question: http://stackoverflow.com/questions/1842636/why-cannot-c-generics-derive-from-one-of-the-generic-type-parameters-like-they-c *without* really offering anything new?

    2. COThis post starts with a phrase - "This post is in continuation of this one.", where "this one" is a hyperlink to the post you are mentioning in your comment. Both posts are created by the same person - me. The first post is a general discussion with pros and cons, whereas here I hope to collect indications from people that this feature is missed by them as well, not just me.

    3. COI think you should move your own starting reason to an answer rather than including it in the question. Your question is much more painful to read as it is now.

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.
