Our friends with WiX (principally blogger Rob Mensching) had some questions about the schema changes. One of those questions was:
Will there be an updated ICE and _Validation table that supports the schema changes?
Windows Installer 4.5 supports adding a new bits
Component table, Attribute column,msidbComponentAttributesUninstallOnSupersedence and msidbComponentAttributesShared bits
Yes, we do have updates to our SDK Tools before we call development complete. We have planned for this work to happen after the engine changes are complete. Our habit is to make sure the engine changes are complete before we shift to SDK tools.
