azure-devops - ASPNETCore 2.1 MVC 应用程序的 Azure DevOps 构建失败

Question

我们正在使用 Azure DevOps，并且我们有一个持续集成的构建管道。当我将我的代码签入 Azure DevOps 分支时，我的构建管道启动并且运行良好。

我们公司是 .NET Core 的新手，因此在学习过程中，我将 ASP.NET Core 2.1 MVC 应用程序添加到我的解决方案中。本地一切正常。当我签入我的代码时，我的 Azure DevOps 构建管道启动，但它失败了。我们的构建管道是 VS Hosted 2017 代理。

我在 Azure DevOps 中遇到以下错误

您是否尝试切换到 VS 2019 代理？虽然我看不出有任何理由根据安装在 VS2017 代理 (1) 上的依赖项而无法正常工作。Microsoft 确实建议使用 VS2019 代理进行 DotNet Core 开发 (2)。

还有其他要研究的问题，您的解决方案中是否有其他项目引用了旧版本的核心，这可能会导致版本冲突？
