adal - 'Microsoft.IdentityModel.Clients.ActiveDirectory.Authenticator' 的类型初始化程序引发异常

Question

使用 OpenId Connect 中间件 (dnxcore50; 1.0.0-beta6-* coreclr x64) 处理 AAD SSO ...

app.UseCookieAuthentication(options => { options.AutomaticAuthentication = true; });
app.UseOpenIdConnectAuthentication(options => {
    options.ClientId = ClientId;
    options.Authority = Authority;
    options.PostLogoutRedirectUri = PostLogoutRedirectUri;
    options.AutomaticAuthentication = true;
    options.SecurityTokenValidators = new[] { new UnsafeJwtSecurityTokenHandler() };
    options.Notifications = new OpenIdConnectAuthenticationNotifications {
        AuthenticationFailed = OnAuthenticationFailed,
        AuthorizationCodeReceived = OnAuthorizationCodeReceived
    };
});

在 OnAuthorizationCodeReceived 中，以这种方式获取 Graph API 的上下文...

string userObjectId = notification.AuthenticationTicket.Principal.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value;
ClientCredential credential = new ClientCredential(ClientId, AppKey);
AuthenticationContext authContext = new AuthenticationContext(Authority);
AuthenticationResult result = await authContext.AcquireTokenByAuthorizationCodeAsync(notification.Code, new Uri(BaseAddress), credential, "https://graph.windows.net");

适用于 dnx451 1.0.0-beta4 clr x86，但不适用于 dnxcore50 1.0.0-beta6-* coreclr x64

The type initializer for 'Microsoft.IdentityModel.Clients.ActiveDirectory.Authenticator' threw an exception.

ClientId、AppKey、Authority、notification.Code 和 BaseAddres 的值应该没问题……它们在两个运行时之间没有改变。依赖是...

"Microsoft.IdentityModel.Protocol.Extensions": "2.0.0-*",
"Microsoft.AspNet.Mvc": "6.0.0-*",
"Microsoft.AspNet.Authentication.Cookies": "1.0.0-*",
"Microsoft.AspNet.Diagnostics": "1.0.0-*",
"Microsoft.AspNet.Server.IIS": "1.0.0-*",
"Microsoft.AspNet.StaticFiles": "1.0.0-*",
"Microsoft.AspNet.Tooling.Razor": "1.0.0-*",
"Microsoft.IdentityModel.Clients.ActiveDirectory": "3.1.203031538-alpha",

"Microsoft.AspNet.Authentication.OpenIdConnect": "1.0.0-*",
"Microsoft.AspNet.Identity": "3.0.0-*",

我也在 AzureAD/azure-activedirectory-library-for-dotnet 发帖，但答案似乎慢慢地到达那里。如果在这里回答，我会在那里更新+关闭。

我也遇到这个问题，我的场景是我在库项目中引用了这个包，然后我在控制台应用程序中调用该方法，然后控制台应用程序会抛出这个异常。

查看控制台应用的debug文件夹，发现漏掉了

Microsoft.IdentityModel.Clients.ActiveDirectory.Platform.dll

所以解决方法是我也在控制台应用程序中引用这个包。
