In my Windows application I set the Title, Product Name and Company Name in the assembly.
I added a setup and deployment project to the solution and added the primary output of the Windows application to it.
When I launch the setup, it does not take the Title, Product Name and Company Name.
What am I doing wrong/forgetting?
In the Solution Explorer, click on your setup and deployment project and then click on the properties tab (or just press F4). The settings you are looking for are there.
