PlatformPlugin异常在ASP.NET Core中使用MSAL获取仅应用程序令牌(PlatformPlugin exception getting app

PlatformPlugin异常在ASP.NET Core中使用MSAL获取仅应用程序令牌(PlatformPlugin exception getting app-only token using MSAL in ASP.NET Core)

我正在尝试创建一个使用MSAL作为客户端凭据流的ASP.NET Core应用程序。

尝试获取访问令牌时出现以下异常：

NullReferenceException: Object reference not set to an instance of an object. Microsoft.Identity.Client.Internal.PlatformPlugin.LoadPlatformSpecificAssembly()

以下示例验证身份验证： active-directory-dotnet-webapp-openidconnect-aspnetcore-v2

授权模仿此示例： active-directory-dotnet-daemon-v2

我的应用程序已注册Mail.Read应用程序权限。 以下是引发异常的代码：

string authority = $"https://login.microsoftonline.com/{ tenantId }/v2.0"; ConfidentialClientApplication client = new ConfidentialClientApplication( authority, appId, redirectUri, new ClientCredential(appSecret), null);//new TokenCache()); AuthenticationResult authResult = await client.AcquireTokenForClient( new string[] { "Mail.Read" }, null); return authResult.Token;

还尝试使用“ https://graph.microsoft.com/.default ”作用域，如守护程序示例中所示。

I'm trying to create an ASP.NET Core app that uses MSAL for the client credentials flow.

I get the following exception when trying to get an access token:

NullReferenceException: Object reference not set to an instance of an object. Microsoft.Identity.Client.Internal.PlatformPlugin.LoadPlatformSpecificAssembly()

Authentication is modeled after this sample: active-directory-dotnet-webapp-openidconnect-aspnetcore-v2

Authorization is modeled after this sample: active-directory-dotnet-daemon-v2

My app is registered with the Mail.Read Application permission. Here's the code that throws the exception:

string authority = $"https://login.microsoftonline.com/{ tenantId }/v2.0"; ConfidentialClientApplication client = new ConfidentialClientApplication( authority, appId, redirectUri, new ClientCredential(appSecret), null);//new TokenCache()); AuthenticationResult authResult = await client.AcquireTokenForClient( new string[] { "Mail.Read" }, null); return authResult.Token;

Also tried with "https://graph.microsoft.com/.default" scope, as in the daemon sample.
