.NET is a free and open-source, managed computer software framework. It is a cross-platform successor to .NET Framework and released under the MIT License.

Adding FreeBSD Support to .NET is currently a work in progress with most work taking place in the following issues:

• dotnet/source-build: GitHub Issue #1139: Building the .NET Core SDK on FreeBSD
• dotnet/runtime: GitHub Issue #14537: Support for FreeBSD

Notably, building .NET requires an existing and working dotnet cli SDK to bootstrap the build, as mentioned in the Workflow Guide: FreeBSD Requirements documentation/

Producing this binary natively for FreeBSD is the aim of upstream issue #1139 mentioned above.

Until native boostrap is available officially from upstream, FreeBSD .NET builds can be produced using either:

1. An existing freebsd dotnet cli binary.
2. A dotnet cli binary built on FreeBSD under Linux Emulation.
