我正在嘗試通過圖形 api 使用 Azure.Identity UsernamePasswordCredential 對 AD 進行身份驗證，但是每當我初始化憑據建構式時，它都會引發以下例外：
The method or operation is not implemented. at System.Diagnostics.Tracing.EventSource.GetSources ()
堆疊跟蹤：
System.TypeInitializationException: The type initializer for 'Azure.Core.Pipeline.LoggingPolicy' threw an exception. ---> System.TypeInitializationException: The type initializer for 'Azure.Core.Diagnostics.AzureCoreEventSource' threw an exception. ---> System.NotImplementedException: The method or operation is not implemented.

我的代碼是 graphService 女巫是一個標準庫 v2.1，它由 Xamarin.forms 專案中的 AuthViewModel 使用。
public class AuthViewModel: BaseViewModel
{
...
private async Task InnerGetUser()
{
try
{
this.IsBusy = true;
if (string.IsNullOrEmpty(this.Email) ||
string.IsNullOrEmpty(this.Password))
throw new ValidationException("Email e password devono essere compilati");
this._graphService.Init(this.Email, this.Password,
this._settingsService.GetStringSetting(Services.Settings.TenantId),
this._settingsService.GetStringSetting(Services.Settings.ClientId),
this._settingsService.GetStringSetting(Services.Settings.EventKeyword));
var user = await this._graphService.GetUser();
this._userService.CurrentUser = new UserDto()
{
Name = user.DisplayName
};
this._userService.InvokeOnLoginDone();
}
catch (Exception e)
{
await base.ShowError(e);
}
finally
{
this.IsBusy = false;
}
}
...
}
public class GraphService: IGraphService
{
...
public void Init(string username, string password, string tenantId, string clientId, string eventKeyword)
{
this._eventKeyword = eventKeyword;
Console.WriteLine("Creo credentials provider");
var userNamePasswordCredential = new UsernamePasswordCredential(
username, password, tenantId, clientId, new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
});
Console.WriteLine("Creo graph service client");
this._graphClient = new GraphServiceClient(userNamePasswordCredential);
}
...
}
奇怪的是，它在 net5 中的控制臺應用程式上運行良好。
掘金：
- Xamarin.forms 5.0.0.2125，
- Azure.Identity 1.4.1，
- Microsoft.Graph 4.6.0
環境：
- mac 作業系統 11.6
- Visual Studio for mac 8.10.10 (build 8)
軟體開發工具包：
- .NET 5.0.401，
- 單聲道 6.12.0.140，
- Xamarin.iOS 15.0.0.6。
有任何想法嗎？
謝謝。

我遇到了類似的問題，Azure.Storage.Blobs 遇到了例外
System.TypeInitializationException: The type initializer for 'Azure.Core.Pipeline.LoggingPolicy' threw an exception. ---> System.TypeInitializationException: The type initializer for 'Azure.Core.Diagnostics.AzureCoreEventSource' threw an exception. ---> System.NotImplementedException: The method or operation is not implemented.
我通過安裝Azure.Core解決了它。我希望它可能對你有用。

我將此作為 Not an answer 發布，因為我遇到了同樣的問題并且我嘗試了這個但沒有成功。我嘗試將所有診斷選項設定為 false。它確實有效果，因為當我創建 BlobServiceClient 時它停止拋出例外，但現在當我迭代列出 Blob 的結果時它拋出 System.NotImplementedException。
ClientSecretCredentialOptions options = new ClientSecretCredentialOptions();
options.Diagnostics.IsDistributedTracingEnabled = false;
options.Diagnostics.IsLoggingContentEnabled = false;
options.Diagnostics.IsLoggingEnabled = false;
options.Diagnostics.IsTelemetryEnabled = false;
