Accepted Answer

In C#, when using the legacy `Microsoft.Azure.Services.AppAuthentication` library to authenticate Azure resources using Managed Service Identity (MSI), you must instantiate an **`AzureServiceTokenProvider`** and then invoke its **`GetAccessTokenAsync`** method to retrieve the access token string. Since the constructor of the `TokenCredential` class in this SDK expects an access token as a string, `GetAccessTokenAsync` is the only method that returns the correct type (`Task<string>`), while `MSITokenProvider` and its methods return an `AuthenticationHeaderValue` object.
