title: MVC - Insert data into multiple entities from same page
body: <p>I have a single page which collects related data into a series of input fields.</p>
  
  <p>When the user clicks submit I want to insert the data into two different database tables in one go. ie I want to get the primary key from the first insert, and then use it for the second insert operation.</p>
  
  <p>I am hoping to do this all in one go, but I am not sure of the best way to do this with the Models/Entities in MVC.</p>
