.NET Support and Compatibility for Linux Distributions

.NET is supported by Microsoft and by various commercial vendors and the community on multiple Linux distributions.

.NET can typically be run on any Linux distribution, via:

  • The Microsoft build, which is built to be broadly compatible.
  • Distribution-specific builds, which are built specifically for a given distribution version (like Red Hat Enterprise Linux 9 or Ubuntu 22.04).

General dependencies

Microsoft builds have multiple dependencies that must be installed:

libc compatibility

Microsoft builds supports both glibc-based and musl libc-based Linux distributions, per the following minimum version information.

You can use the following pattern to determine the libc version provided for your distribution.

On Alpine 3.16:

# ldd --version
musl libc (aarch64)
Version 1.2.3

On Ubuntu 22.04:

# ldd --version
ldd (Ubuntu GLIBC 2.35-0ubuntu3.1) 2.35

OpenSSL compatibility

Microsoft builds support both OpenSSL 1.x and 3.x and can be run on distributions with either version of this package. For example, Ubuntu 22.04 only includes OpenSSL 3 in its official package archive.

Microsoft builds will generally load the highest OpenSSL version it finds, but can be configured to use a specific version.

Red Hat Enterprise Linux Family support

Microsoft builds support multiple Red Hat versions. New .NET versions will typically only be supported on RHEL era distributions in active support.

  • RHEL 7 era distributions are considered in maintenance.
  • RHEL 8 era distributions are considered in active support.
  • RHEL 9 era distributions are considered in active support.

Red Hat family distributions include: AlmaLinux, CentOS, Oracle Linux, Red Hat Enterprise Linux, and Rocky Linux.

Red Hat Commercial Support

Red Hat supports .NET via Red Hat Enterprise Linux, per the following.

  • .NET 6 is supported in RHEL 7+.
  • .NET 7 is supported in RHEL 8+.

Ubuntu Commercial Support

Canonical supports .NET on Ubuntu via APT archives, per the following.

  • .NET 6 is supported in Ubuntu 22.04+.
  • .NET 7 is supported in Ubuntu 22.10+.
