           Summary: Removing a constraint from a DataTable does not
                    nullify it from DataRelation
    Classification: Mono
           Product: Mono: Class Libraries
           Version: 2.6.x
          Platform: x86

            Status: NEW
          Severity: Normal
          Priority: P5 - None

- When removing a ForeignKeyConstraint from a DataTable, any related
DataRelation's ChildKeyConstraint property should be nullified.
- When removing a UniqueConstraint from a DataTable, any related DataRelation's
ParentKeyConstraint property should be nullified.


Reproducible: Always

Steps to Reproduce:
1. Create a DataSet, a parent DataTable, a child DataTable and a DataRelation
relating the 2 tables.
2. a UniqueConstraint will be created on the  and a ForeignKeyConstraint.
3. Remove the UniqueConstraint from the parent table. This should cause
DataRelation.ParentKeyConstraint to become null.
4. Remove the ForeignKeyConstraint from the child table. This should cause
DataRelation.ChildKeyConstraint to become null.

Actual Results:  
DataRelation still has a reference to the ChildKeyConstraint and
ParentKeyConstraint, even though those constraints don't exist on the
DataTable.

Expected Results:  
- When removing a ForeignKeyConstraint from a DataTable, any related
DataRelation's ChildKeyConstraint property should be nullified.
- When removing a UniqueConstraint from a DataTable, any related DataRelation's
ParentKeyConstraint property should be nullified.
