ASP.NET Zero vs ASP.NET Core: What are the differences?
Developers describe ASP.NET Zero as "Base solution for web applications". It is a starting point for new web applications with modern UI and SOLID architecture. It saves time by providing common application requirements as a pre-built Visual Studio solution (with full source code). On the other hand, ASP.NET Core is detailed as "A cross-platform .NET framework for building modern cloud-based web applications on Windows, Mac, or Linux". A free and open-source web framework, and higher performance than ASP.NET, developed by Microsoft and the community. It is a modular framework that runs on both the full .NET Framework, on Windows, and the cross-platform .NET Core.
ASP.NET Zero and ASP.NET Core can be categorized as "Frameworks (Full Stack)" tools.
ASP.NET Core is an open source tool with 16.2K GitHub stars and 4.29K GitHub forks. Here's a link to ASP.NET Core's open source repository on GitHub.
