这简直要了我的命。我已经清除了有问题的程序包，卸载了程序包，重新安装，尝试添加<PackageReference>，尝试使用<targetFrameworks>针对多个框架。。。所有这些，我在运行时仍然会遇到这个错误。
我有一个。NET Standard 2.0库，该库正由。NET Framework 4.8项目。该框架项目没有引用任何IdentityModel。令牌/Jwt对象。我已经手动将程序集从中的包位置复制到有问题项目的bin文件夹中，它似乎没有改变结果。

在对其进行了额外的观察之后，发现引用的根项目文件(我们做的事情有点不同(。NET Framework项目需要对未加载的程序集的引用。
不知道为什么，但可能与MVVM有关，并使用根项目作为应用程序的包装器/驱动程序。
