Azure.Identity.IMsalManagedIdentityInitializerOptions

Implemented by TokenCredentialOptions-derived types that need to customize the AcquireTokenForManagedIdentityParameterBuilder immediately before the token is acquired. This is used, for example, by the Azure.Identity.Broker package to attach WithAttestationSupport() (from the Microsoft.Identity.Client.KeyAttestation package) without forcing Azure.Identity itself to take a dependency on that package.
namespace Azure.Identity { internal interface IMsalManagedIdentityInitializerOptions { Action<AcquireTokenForManagedIdentityParameterBuilder> BeforeTokenAcquisition { get; } } }
