container for a set of objects. It contains a key called Items (whose value is an array of the requested objects) along with other keys like Previous, Next and Limit which can be useful in future calls.</p></blockquote><p>It allows you to only receive a subset of all available data and dynamically check if more requests are required. The library supports <code>Paging<T></code> responses in two ways:</p><h2><a aria-hidden="true" tabindex="-1" class="anchor enhancedAnchor_2LWZ" id="paginateall"></a>PaginateAll<a class="hash-link" href="#paginateall" title="Direct link to heading">#</a></h2><p><code>PaginateAll</code> will query all remaining elements based on a first page and return all of them in an <code>IList</code>.
