As pointed by <a href="https://stackoverflow.com/users/60188/anton-gogolev">Anton Gogolev</a>, attributes can be created using PostSharp.(note that CodeContract is using static method calls inside body of method) UPDATE Feb 2013: new 3.0 release of PostSharp (currently in Beta) will support <a href="http://www.sharpcrafters.com/blog/post/Validating-parameters-field-and-properties-in-PostSharp-3.aspx" rel="nofollow noreferrer">Validating parameters, fields and properties</a> 1) Article <a href="http://dpatrickcaldwell.blogspot.com.au/2009/03/validate-parameters-using-attributes.html" rel="nofollow noreferrer">validate-parameters-using-attributes</a> has implementation of <blockquote> public class NotEmpty : ParameterAttribute public class NotNull : ParameterAttribute [AttributeUsage(AttributeTargets.Parameter)] public abstract class ParameterAttribute : Attribute { <pre><code>public abstract void CheckParameter(ParameterInfo parameter, object value); </code></pre> } </blockquote> It also Required a method attribute with a method boundary aspect to process the parameter attributes. 2) In the comment to the article there are links to <a href="http://code.google.com/p/postsharp-user-plugins/wiki/DesignByContract" rel="nofollow noreferrer">very similar implementation</a> for NonNull/NonEmpty <blockquote> [return: NonNull] public SomeObject SomeMethod([NonNull] AnotherObject param1) </blockquote> The source code is located In <a href="http://postsharp-user-plugins.googlecode.com/svn/trunk/1.5/Torch/DesignByContract.Weaver/" rel="nofollow noreferrer">google code Torch/DesignByContract</a> 3) another more complicate example is described in <a href="http://badecho.com/2011/11/validating-method-parameters-with-postsharp/" rel="nofollow noreferrer">http://badecho.com/2011/11/validating-method-parameters-with-postsharp/</a>

Guidance

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.
