c# - 最新的 ADAL 无法生成不记名 token

Question

我正在尝试使用以下代码使用最新版本的 ADAL 包 (3.13.9) 生成 authcontext，但出现异常。但是，我将 ADAL 版本降级到 v2.22.302111727，它可以正常工作。我使用的是 Visual Studio 2017。3.13.9 有什么问题吗？

authContext = new AuthenticationContext(authority, true);

System.TypeInitializationException occurred HResult=0x80131534
Message=The type initializer for 'Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext' threw an exception.

听起来您可能遇到了这个问题:

我正在使用isabekyan's workaround ，因为这已经解决了我的问题。

他们建议在使用authenticationContext之前添加对以下代码的调用

  private static void SomeMethodToLinkPlatform()
    {
        var creds = new UserPasswordCredential("testUser", "SomePassword");
    }
