title: LINQ to SQL - Nullable INT in ForeignKey = "Cannot create an association..."
body: <p>I have a table that has a primary key that's an INT... I have another table, that has a foreignkey relationship to that first table, but it's a NULLABLE INT.</p>
  
  <p>This is perfectly ok, and 100% acceptable to SQL... however LINQ to SQL is complaining about mismatched types ("int to Nullable[int]").</p>
  
  <p>Error Message: Cannot create an association "Store_People". Properties do not have matching types: "PersonID", "ID".</p>
  
  <p>How do I solve this so that the designer stops yelling at a 100% correct usage of SQL?</p>
