There is no checking in System.Data.DataRowCollection.Add(DataRow row)
that there is no violation of the unique constrains.
Steps to reproduce the problem:
1. Add DataRow to a DataTable that has a uniqueConstraint on one of the
2. Try to add a second DataRow that has the same value in the
uniqueConstaraint column.
Actual Result:
The row is added to the table.
Expected Result:
A ConstraintException should be thrown.
Enclosed is a small test case and a patch.
