Can I use CustomActionAttribute in classes that inherit from System.Configuration.Install.Installer? I want my class library to support both WiX and Visual Studio setup project.
The reasons for not doing it are: you can't have methods with same names in your custom actions assembly custom action method calls in WiX And the DTF methods and VS setup project methods are different in signature. Also, as I've understood, VS setup project CAs don't use Session object, unlike DTF CAs.
