.NET Core 2.2 End of Life Is Dec. 23
Microsoft has advised developers that .NET Core 2.2's support life will end next Monday, Dec. 23, so they should upgrade.
For .NET Core 2.2, the supported upgrade path is to .NET Core 3.1, which shipped a few weeks ago as a long-term support (LTS) release, meaning it will enjoy free Microsoft support for three years.
In the Microsoft scheme, non-LTS releases -- also called "Current" releases -- are supported for three months after a subsequent release, so, because .NET Core 3.0 was released on Sept. 23, .NET Core 2.2 is supported until Dec. 23. "After that time, .NET Core patch updates will no longer include updated packages of container images for .NET Core 2.2," Microsoft said earlier this month. "You should plan your upgrade from .NET Core 2.2 now."
Migrating from 2.2 to 3.1 is straightforward, Microsoft said, simply requiring developers to update a project file to use v3.1 rather than v2.2. For other likely migrations, the above-referenced post includes links to instructions on migrating from .NET Core 2.0 to 2.1 and migrating from ASP.NET Core 2.2 to 3.0.
Here's Microsoft's explanation of the support policy:
LTS releases include features and components that have been stabilized, requiring few updates over a longer support release lifetime. These releases are a good choice for hosting applications that you do not intend to update often.
Current releases include features and components that are new and may undergo future change based on feedback. These releases are a good choice for applications in active development, giving you access to the latest features and improvements. You need to upgrade to later .NET Core releases more often to stay in support.
