TODO:
You try to insert a record using the Entity Framework and get the following error:
"Unable to update the entityset because it has a defining query and no <UpdateFunction> element exists in the <ModificationFunctionMapping> element to support the current operation"
SOLUTION:
Add a primary key to the table. Also make sure the Concurrency Mode of the Primary Key is set to "Fixed" (right click column, choose properties)
