使用 C# 构建的 Gitlab CI

Question

我创建了一个 C# 项目 ( C# 7.0& .net framework 4.7.2)，并添加了一些单元测试 ( NUnit 3.11.0)。

该代码存储在 Gitlab 存储库中，我可以在本地运行测试和构建。但现在我想通过 Gitlab CI 自动执行此操作。根据这篇stackoverflow 帖子和互联网上的很多文章，您应该在 Windows 计算机上创建自己的运行器。

但其中大多数答案已经很旧了，Gitlab CI 现在可以使用 Docker 镜像。但后来我遇到了我的问题。我应该为这个跑步者使用什么图像？我尝试过microsoft/dotnet-framework和microsoft/dotnet但这些都不起作用。

给出microsoft/dotnet-framework错误消息：No such image: microsoft/dotnet-framework

并且microsoft/dotnet图像不包含.net 4.7.2库，因此它不能用于构建。

Gitlab CI + Docker 镜像 + C# 构建？

是否仍然无法使用用于 C# 构建（控制台应用程序）的 Docker 映像创建 Gitlab CI 运行器？或者我只是在这里做错了什么？

我当前的 .gitlab-ci.yml

image: microsoft/dotnet-framework

stages:
  - build

before_script:
  - 'dotnet restore'

app-build:
  stage: build
  script:
    - 'dotnet build'
  only:
    - master

更新

感谢@Andreas Zita 我现在有了一张图片 ( dsfnctnl/gitlab-dotnetcore-builder:0.15.0)。不幸的是，这给了我与microsoft/dotnet. 这可能是我的构建脚本中的一个错误（或者我希望如此），但我似乎找不到它是什么。

错误：

Mono 图像正在帮助我在 GitLab 中构建 C# 应用程序。

    image: mono:4.4.0.182

     stages:
      - build
    app-build:
      stage: build
      script:
        - MONO_IOMAP=case xbuild/t:Build/p:Configuration="Debug"/p:Platform="x86"
          myApp.sln
    only:
       - master

平台可能会根据构建配置（如 AnyCPU）而改变。
