net48至net60迁移：无法加载文件或汇编＆＃x27; system.runtime，版本= 6.0.0.0 ...＆＃x27;

Question

我将申请迁移到Net48到Net60。在迁移期间，我必须更新我的自定义Nuget软件包以支持Net60并将其添加到我的应用程序中，但是在构建过程中，我会遇到一个错误：

wcfwrappergenerator.targets（36，5）：无法加载文件或汇编 'System.Runtime，版本= 6.0.0.0，culture =中性， publicKeyToken = B03F5F7F11D50A3A'或其依赖项之一。这 系统找不到指定的文件。

错误的实际位置（第36行）：

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

我该如何修复？

另外，在尝试获得代码分析时，我会看到一个错误：

Answer 1

解决方案中的另一种可能性，.licx文件。 licx中的API移至其他许可证验证方法，我没有更新代码。问题在nuget更新api之后开始。
