Bug #: 243 (SQL Hotfix)



SYMPTOMS
Consider the following scenario. You fill a DataTable object that contains a String, Byte[], or Object column type. Then, you clear rows from the DataTable object. In this scenario, not all the memory that is used in the Microsoft ADO.NET 1.1 DataSet object is released.

When a row is removed or the DataTable object is cleared, the reference to the values is not released. This problem does not affect primitive values, such as Int32, Decimal, or DataTime data types. This problem only affects reference types, such as the String, Byte[], or Object data type.

Note This problem does not apply to Microsoft ADO.NET 2.0.
