title: Create a typed dataset from code
body: <p>for the purpose of a test, I would like to mock my typed dataset. So I want to create it, with appropriate value, with C# code.
  But I don't know how to do that. Each tutorial I see, are about non-typed dataset.</p>
  
  <p>Has someone an example ? Or maybe a link that explain this ?</p>
  
  <p>Thanks in advance for your help</p>
