OWIN in ASP.NET MVC5 WebAPI vs Upgrading to ASP.NET Core The decision to continue using OWIN in your ASP.NET MVC5 WebAPI or to upgrade to ASP.NET Core depends on several factors, including the size of your project, the time and resources available for the upgrade, and the specific needs of your application. OWIN (Open Web Interface for .NET) is a standard for an interface between .NET web applications and web servers. It's a middleware that helps inject pipelines to pre-process requests in stages. It's important to note that while ASP.NET Core is not built on OWIN, it is OWIN-compatible. This means you can still use OWIN libraries in your ASP.NET Core applications if you choose to upgrade . ASP.NET Core, on the other hand, is a modular, portable, open-source framework with a new implementation of the Common Language Runtime. It's designed to be a more modern, flexible, and configurable version of ASP.NET. It also has built-in support for OWIN, which means you can leverage OWIN-based servers' features, like WebSockets, in your ASP.NET Core applications. However, upgrading to ASP.NET Core from ASP.NET MVC5 can be a significant undertaking, especially for large projects. The migration process may involve changes to the middleware pipeline, the startup file, and potentially other areas of your application. It's also worth noting that the authentication infrastructure in ASP.NET Core has changed, and you may need to adjust your application's authentication logic accordingly. Conclusion: if your application is currently working well with OWIN in ASP.NET MVC5 and you don't have a pressing need for the features and improvements offered by ASP.NET Core, it may be more practical to stick with your current setup. However, if you're looking to take advantage of the new features and improvements in ASP.NET Core, and you have the time and resources to handle the migration process, then upgrading could be a worthwhile investment.
