title: how to add EntryCell to Xamarin.Forms Content
body: <p>I am new on <strong>Xamarin.Forms</strong> and I am trying to use <code>EntryCell</code> </p>
  
  <pre><code>AccountId = new EntryCell {Label="Account Id", Text = CustomersPage.staticCustomer.AccountId};
  </code></pre>
  
  <p>When I am trying to add <code>EntryCell</code> to content page:</p>
  
  <pre><code>Content = new StackLayout {
      Children = {
          AccountId              
      }
  };
  </code></pre>
  
  <p>I get the following error:</p>
  
  <blockquote>
    <p>The best overloaded Add method
    'System.Collections.Generic.ICollection.Add(Xamarin.Forms.View)'
    for the collection initializer has some invalid arguments</p>
  </blockquote>
  
  <p>Why can't I add <code>EntryCell</code> directly just like <code>Entry</code>?</p>
