How can an Add-In interact with another Add-In?

Hi all!

Last year I developed an Add-In which works together with an Extension. In the Add-In code i get the extension with these rows:
Dim extensionID As New UIDClass()
extensionID.Value = "Id_of_Extension"
Dim pExtension As IExtension = pApplication.FindExtensionByCLSID(extensionID)

After these rows the Add-In calls methos from the Extension and this works fine.
But now we are converting the extension to an Add-In and I need a similar solution to get the Add-In. I don't find code examples on the ESRI sites. Maybe I use the wrong search words ;)
Is there a similar method to get an Add-In for working with it?
