OnChanged doesn't work after some time

[viveknuna]

I have implemented Table Depedendy in my code. It works fine but after some time it does not work. It doesn't call the OnChanged event.
I need to restart the application to make it work.

Is there any permanent solution to this problem?

SqlTableDependency<MyTable> _myTable = null;
_myTable = new SqlTableDependency<MyTable>(connectionString, "MyTable");
_myTable.OnChanged += OnChanged;
