VS Setup Project

Question

I'm creating a new Setup project for the first time and I have a couple of questions I'd appreciate help on: 1. How do I specify that I want the setup to always overwrite or uninstall any previous version of my app. That is I don't want to require the user to have to uninstall and then re-install when I provide updates. I noticed that the Project/Install menu action in Visual Studio does this very nicely but when I test my msi file directly it prompts the user to uninstall first and then re-enter the install. 2. Not really a Setup question but if I target version 1.1 of the framework will this likely work on the upcoming release version of 1.2? I know that apps developed with VS 2002 work this way - they automatically are work with both version 1.0 and version 1.1 of the framework. Once I get this install the way I want it - I don't want to have to do separate installs for 1.1 and 1.2.

That's exactly what I want to happen but the msi file I get does not lead to that behavior. Only when I test Install from within the Visual Studio IDE does it do that.

Hi I have created a simple sample app. in C# that shows me a dialog box. I then used the new Setup and Deployment Projects ' Setup Project within the same. After this when I try to reinstall my app with the previous one left as it is the setup removes the previous instance and installs the new one. By this I understand that the .NET Setup & Deployment project does check for the existing one and if exists uninstalls it and installs it. The user does not have to do any thing just start the installation process and the setup takes care of. For the second question not sure and also could not understand Thanks irfan
