[wix-users] Calling DLL Interfaces from Wix

[Jayaprakash, Bs]

Thanks. I heard from few folks saying "Difx" will not be supported by Microsoft going forward. So I am trying to write DLL which uses windows APIs to install the driver.

Regards,

Not sure if this will help, but WiX comes with an extension to install
drivers:
http://wixtoolset.org/documentation/manual/v3/xsd/difxapp/driver.html

But back to your question, you might have to 'wrap' your C DLL with a C++ or
C# custom action DLL, i.e. use DllImport

i.e.:
[DllImport("advapi32.dll", EntryPoint = "CloseServiceHandle")]
        public static extern int CloseServiceHandle(IntPtr hScObject);
