OnChange fires as I need, but I don\'t understand if it\'s possible to get the row which caus

Answer 1

Just use a cross-platform .NET 3.5 compatible and open-source SqlDependencyEx. It uses a database trigger and native Service Broker notification to receive events about the table changes. This is a usage example:

int changesReceived = 0;
using (SqlDependencyEx sqlDependency = new SqlDependencyEx(
          TEST_CONNECTION_STRING, TEST_DATABASE_NAME, TEST_TABLE_NAME)) 
{
    sqlDependency.TableChanged += (o, e) => changesReceived++;
    sqlDependency.Start();

    // Make table changes.
    MakeTableInsertDeleteChanges(changesCount);

    // Wait a little bit to receive all changes.
    Thread.Sleep(1000);
}

Assert.AreEqual(changesCount, changesReceived);

You can get change notifications as well as information which was changed. Please follow the link for details.
