This post serves as a tutorial for creating a MSI installer for your WPF Applications in Visual Studio. For this we use WiX (recommended by Microsoft). Prerequisites I assume you already have a Visual Studio solution containing a WPF Project. And I assume you have some experience with Visual Studio and XML. You do not need any prior knowledge of WiX. Step 1: Install Wix We are going to need WiX to generate our MSI. If you don't already have Wix installed, go ahead and download it from here . You'll be redirected to the relevant GitHub releases page where you can download the .exe file to install WiX.
