.NET Support Policy

Last updated: May 18, 2023

.NET and .NET Core

.NET and .NET Core refer to several technologies including the runtime, the SDK, ASP.NET Core, and Entity Framework Core.

Supported versions

The following table tracks release and end of support dates for .NET and .NET Core versions.

Release schedule

Major .NET versions are released annually in November. Each .NET release is defined as either Standard Term Support (STS) or Long Term Support (LTS), at the beginning of the release.
STS releases are released in even-numbered years and LTS releases are releases in odd-numbered years.
The quality of all releases are exactly the same, the only difference is the length of support. LTS releases get free support and patches for 3 years.
STS releases get free support and patches for 18 months.

Patch updates are released monthly on the second Tuesday of each month, also known as Patch Tuesday. Within a release's support lifecycle, systems must remain current on released patch updates. Patches to releases are compatible, which eliminates risk adversely affecting applications.

For details, see the .NET and .NET Core support policy.

STS releases were previously known as Current releases.
