[wix-users] how to call a c# custom action from a dll which is installed along with the product

[Hoover, Jacob]

I think what you are missing is that your install is required to be installed before you run this "CA". When I said exe, I was leaning towards an exe that you run, from the installed folder.  (Loading an assembly from something other than the original ApplicationBase is not trivial).

Note, having this as an exe means whatever you are changing with it, you should configure your package to attempt to clean up in the case of an uninstall.

dont get me wrong, i think you misunderstood my scenario, I don't have an exe, i have  a c# dll that i needs to be deployed in the machine. There is one CA i needed to execute from it and since this dll CA requires supporting dlls i cant put this dll in the binary table and execute. Is is possible, can you provide any sample code or any way to do it, it will be much helpful.
