title: framework for ASP.net to have users and transactions
body: <p>I want to create users who then can be tied to transactions.
  Think ebay, where there are users who are tied to a sell/buy.</p>
  
  <p>And then I would want to have a url that points back to the transaction.</p>
  
  <p>Is there an ASP.net framework that already does this?</p>
  
  <p>I am thinking about having a SQL table that has the transaction and also has keys to point to users but if there is a model or framework that already does it I don't want to redo that.</p>
