Sql Dependency With Service Broker

I have written a windows service for one of our local servers. This service works like a gem on my local machine, does what it's supposed to (ACCP to exchange db data), but I'm not

Solution 1:

Be careful using the SqlDependency class to monitor changes in the database tables - it has the problems with the memory leaks. However, you can use your own realization with DDL triggers and SQL Service Broker API or use one of an open source projects, e.g. SqlDependencyEx:

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);

Hope this helps.
