问题 On my forgot password form, the jquery ajax post is fired multiple times (one more after each submit). So if the user enters an invalid email 3 times, and then a valid email, the user gets 4 password-changed emails.

问题 When working with Viewmodels from linq to sql I have an architectural problem. When you have an object from your db (let's say "person"), and you load it in your viewmodel. After this in your view, when you try to acces referenced classes (let's say a person has children object which is a different table in db, and a different datacontext object). You get a "cannot access disposed datacontext object (or something) which is logical, because you loaded your object and disposed the datacontext.
