title: Bogus, AutoFixture, others(?): How to fill a nested model with fake data and set rules for specific properties?
body: <p>I have a very nested model that I want to create thousands of with fake data. But, also, some properties in the model need to be in a specific range or have specific rules. I looked at these two fake data generators:</p>
  
  <p><strong>AutoFixture</strong> only seems to generate fake data for everything.</p>
  
  <p><strong>Bogus</strong> can set rules like ranges for properties but all other properties remain null - or you have to define rules for all of them.</p>
  
  <p>Did I miss something or is it not possible to fill the models with fake data and only set rules for specific properties?</p>
