ASP.NET Versions

ASP.NET is a web platform that provides the services that you require to build server-based web applications. It is built on the .NET Framework, so all .NET Framework features are available to ASP.NET applications. To create ASP.NET web applications, you can use Visual Studio. The tools and options in Visual Studio Community that are designed for creating web applications are referred to collectively as ASP.NET:
ASP.NET 4.7.1 (a stable release)
It is built from the ground up for building modern cloud-based web applications and is part of the .NET Framework 4.7.1 using Visual Studio Community 2017.

ASP.NET 4.5
It is part of the .NET Framework 4.5 using
  • Visual Studio 2013 Express and
  • Visual Studio 2013 Express for Web.

ASP.NET 3.5
It is part of the .NET Framework 3.5 using
  • Visual Studio 2008 Express and
  • Visual Web Developer 2008 Express Edition.

ASP.NET 2.0
It is part of the .NET Framework 2 using
  • Visual Studio 2005 Express and
  • Visual Web Developer 2005 Express Edition.
Again, ASP.NET 4.7.1 is different from ASP.NET 2.0, but unlike ASP, the ASP.NET 2.0 applications/programs can still work on ASP.NET 4.7.1. However, most ASP.NET tutorials such as ASP.NET QuickStart Tutorial still uses ASP.NET 2.0/1.0. Our ASP.NET class demonstrations will use ASP.NET 4.7.1, but the slide materials will use both ASP.NET 2.0 and 4.7.1.
