可以加载文件或程序集 Microsoft.IdentityModel.Tokens.dll/Microsoft.IdentityModel.Tokens.Jwt.dll

如何解决可以加载文件或程序集 Microsoft.IdentityModel.Tokens.dll/Microsoft.IdentityModel.Tokens.Jwt.dll

这让我很伤心。我已经清除了有问题的软件包，卸载了软件包，重新安装，尝试添加 <packagereference>，尝试使用 <targetFrameworks> 定位多个框架......所有这些，我仍然在运行时收到此错误.

我有一个 .NET Framework 4.8 项目正在使用的 .NET Standard 2.0 库。框架项目不引用任何 IdentityModel.Tokens/Jwt 对象。我已手动将程序集从包位置复制到有问题项目的 bin 文件夹中，但结果似乎没有改变。

解决方法

在对其进行额外检查后，结果证明引用 .NET Framework 项目的根项目文件（我们做的事情略有不同）需要对未加载的程序集的引用。

不知道为什么，但可能与 MVVM 以及使用根项目作为应用程序的包装器/驱动程序有关。
