我有一个 .NET Framework (4.5.2) 类库，我想在我们单独开发 ASP.NET Core 应用程序时使用 Microsoft.Extensions.DependencyInjection。
我使用 nuget 安装它，当我使用 Visual Studio 构建时它工作正常，但尝试在 TeamCity 构建代理上使用 MSBuild 构建它给了我很多这样的信息:
MyClass.cs(32, 26): error CS0012: The type 'IServiceProvider' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.ComponentModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

一些 nuget 包(如 Microsoft.Extensions.DependencyInjection 本身)没有单独的 net452 程序集，只有 netstandard1.0 或 netstandard1.1。这可能是问题所在吗？我在构建服务器上安装了 .NET Core SDK 但没有效果。
最佳答案
我遇到了同样的问题，但在使用 NuGet Installer 作为构建步骤后，我的所有问题都得到了解决。
在构建项目之前，您只需要做一件事 - 只需添加一个构建步骤并选择 Runner type 作为 NuGet Installer
您可以从这个截图中查看:
