Remarks
Several predefined specialized subclasses are provided for common standard tables. Subclasses for additional standard tables or custom tables are not necessary, but they are easy to create and make the coding experience much nicer.When creating subclasses, the following attributes may be useful: «see T:WixToolset.Dtf.WindowsInstaller.Linq.DatabaseTableAttribute» , «see T:WixToolset.Dtf.WindowsInstaller.Linq.DatabaseColumnAttribute»
