This post only applies if you’re using ASP.NET Core on .NET Framework.

ASP.NET Core users on .NET Framework should update to the latest ASP.NET Core 2.3 release to stay in support. This update enables ASP.NET Core 2.2 users to update to a supported version by doing a NuGet package upgrade instead of a downgrade. ASP.NET Core 2.1 users updating to ASP.NET Core 2.3 should experience no change in behavior as the packages contain the exact same code. ASP.NET Core 2.2 users may need to remove any dependencies on ASP.NET Core 2.2 specific changes. Any future servicing fixes for ASP.NET Core on .NET Framework will be based on ASP.NET Core 2.3.

Microsoft making changes for something five years out of support (the 2.2 version).
