I have been tasked to write a program that will run during the installation of my companies software. Currently when installing our software a configuration program is launched and a form comes up with some options available. The user chooses which options they want and the program creates some settings in the registry. My boss wants this program rewritten and to run in the background during installation without any type of user interface. My question is this. Can I create a C# project that compiles to an exe without a user interface. The only option I see is to create a windows application and that is not what I want. Any suggestions on how I should handle this? As you can probably tell I am fairly new to programming. Thanks.
