<Description>Code snippet to help you make properties based on 'Dependent&lt;T&gt;', an Update Controls class that represents a value computed based on one or more Independents. Note: in most cases you should just write a normal property instead of using Dependent&lt;T&gt;. Dependent&lt;T&gt; is useful to cache the result of a computation when the value of the property is expensive to compute.</Description>
