Creating an entry point in a C# DLL to call from WIX

I am trying to find a way to create an entry point for my C# DLL. I am aware of how to call other DLL's in C# but cannot find how to create one. I need this in order to call it in my WiX installer as a customer action.

Solution

  • All you need to do is mark your method up with the CustomAction attribute.

    So:

    [CustomAction] 
public static ActionResult MyThing(Session session) 
{ 
  // do your  stuff...
  return ActionResult.Success; 
}

    As you are already calling other C# assemblies from WiX, it sounds like you have WiX 3.0, which supports the managed wrappers.
