Hi

I'm getting warning:
While testing against 06.00.00 it was detected that a DotNetNuke core SQL object (TestQualifier_Modules) was modified by this extension

I think it applies to SQL script that create foreign key:
ALTER TABLE {databaseOwner}[{objectQualifier}GS_ADProUserDirectory_Properties]
ADD CONSTRAINT FK_{objectQualifier}GS_ADProUserDirectory_Property_ModuleID FOREIGN KEY (ModuleID) REFERENCES {databaseOwner}[{objectQualifier}Modules](ModuleID)

How can I add foreign key constraint without warning message?

I fully understand the consequences. 

Do you have a working strategy to delete records from the content of a custom module when the module itself is deleted by admin/cleanup/recycle bin? There is no such thing as a OnDeletModule event you can subscribe to...
