ASP.NET is made up components that ship in both the .NET Framework and as external packages that ship outside of the .NET Framework.
Looking for the support policy for another part of the .NET platform? See .NET Support Policy.
Many parts of ASP.NET are a part of the Microsoft .NET Framework, these include ASP.NET Web Forms, Controls, Modules, Handlers, and more. For more information see .NET Framework support policy.
The support life-cycle policies for .NET Core and .NET 5, ASP.NET Core, and Entity Framework Core can be found in .NET 5 and Core support policy.
To help facilitate migrating applications to ASP.NET Core on .NET Core, the following ASP.NET Core 2.1 (latest patched version only) packages will be supported on the .NET Framework and follow the support cycle for those .NET Framework versions. ASP.NET Core 2.1 is defined as "Tools" in the Microsoft Support Lifecycle Policy. A "Tool" requires a minimum of 12 months notification prior to the end of support. For more information, please see this KB Article.
