Deployment Strategies for Visual Studio Applications Without Installation: A Portable Solution Based on ClickOnce
This paper explores how to implement a deployment solution for C#/.NET applications that can run without installation. For tool-type applications that users only need occasionally, traditional installation methods are overly cumbersome. By analyzing the ClickOnce deployment mechanism, an innovative portable deployment approach is proposed: utilizing Visual Studio's publish functionality to generate ClickOnce packages, but skipping the installer and directly extracting runtime files to package as ZIP for user distribution. This method not only avoids the installation process but also maintains ClickOnce's permission management advantages. The article details implementation steps, file filtering principles, .NET runtime dependency handling strategies, and discusses the application value of this solution in development testing and actual deployment.
