Net48 到 net60 迁移：无法加载文件或程序集“System.Runtime，版本=6.0.0.0...”

Question

我正在将我的应用程序从 net48 迁移到 net60。在迁移过程中，我必须更新自定义 NuGet 包以支持 net60 并将其添加到我的应用程序中，但在构建过程中，我收到错误：

WcfWrapperGenerator.targets(36, 5)：无法加载文件或程序集 'System.Runtime，版本=6.0.0.0，文化=中性， PublicKeyToken=b03f5f7f11d50a3a' 或其依赖项之一。这 系统找不到指定的文件。

实际出错的地方（第36行）：

<GenerateWrappers ContractsAssemblies="@(_source)"
                  ContractsReferences="@(_references)"
                  OutputNamespace="$(GenWithNamespace)"
                  OutputPath="$(GenWrapperFilesPath)">

我该如何修复它？

此外，在尝试进行代码分析时，我看到一个错误：

另一种可能性是解决方案中的 .licx 文件。 licx 中的 API 已转移到不同的许可证验证方法，并且我没有更新代码。问题是在 API 的 nuget 更新后开始的。
