.NET 7이 이제 Linux on Power (ppc64le)에서도 지원됩니다. 즉 ppc64le 아키텍처의 Power 서버에서는 C# 언어도 지원하게 되었습니다. 이로써 microservices app 개발에 사용되는 5개 프로그래밍 언어가 모두 ppc64le에서 지원됩니다.
2021년 Stack Overflow에서의 개발자 설문에 따르면 .NET framework은 전업 개발자들에게 있어서 가장 중요한 프레임웍 및 라이브러리입니다.
관련 발표는 아래 URL에서 좀 더 자세히 보실 수 있습니다.
또한 .NET 7 ppc64le는 이미 고객 reference가 있습니다. 독일의 컴퓨터 설계 관련 기업인 SKM Informatik GmbH인데, 이 기업의 요청으로 .NET 7의 ppc64le 지원이 시작되었다고 합니다.

.NET 7은 github에 그 source code가 공개되니 직접 build 하셔도 됩니다만, .NET 7 for ppc64le는 Openshift container 이미지로 제공되고 또 RHEL 8.7 또는 RHEL 9.1에서 YUM repository를 통해서도 제공됩니다.
.NET 7 관련된 패키지들은 yum 명령어를 통해 패키지로 아래 예와 같이 설치하실 수 있습니다.

Hello, World!
다만 아래의 MS 홈페이지의 .NET download 사이트에서는 ppc64le 관련 패키지는 별도로 제공되지 않네요.
