Visual Studio 2005 Project Property Change Event

[bong]

Hello

I'm trying to add a functionality for visual studio add-in in which it will
synchronize a project's pom.xml if there are any changes in the project
properties.
unfortunately all I could find is an event listener only for
OnReference_Removed, Reference_Added or Reference_updated  these are only
for references
and not for project properties.

I hope if someone has any Idea how to do this.


Thanks
Bong
