Entity Framework Non-nullable column is mapped to a nullable entity property

Question

I am getting this nullable column error message in Entity Framework 4.1 - when the column is not actually nullable: ``` Non-nullable column MyView.RunningTotal in table TransactionListView is mapped to a nullable entity property. ``` But you can see from the screenshots below that the column is not nullable and that the entity property is not nullable either. So why is this error occurring?

Accepted Answer

The straight-forward solution is to manually specify Nullable parameter to True.
