# ICorProfilerCallback::AppDomainShutdownStarted Method

Notifies the profiler that an application domain is being unloaded from a process.

## Syntax

HRESULT AppDomainShutdownStarted(
[in] AppDomainID appDomainId);


## Parameters

appDomainId
[in] Identifies the domain in which the application's assemblies are stored.

## Remarks

The value of appDomainId is not valid for any information request after the AppDomainShutdownStarted method returns — this is the profiler's last chance to get information about this application domain.

## Requirements

Platforms: See System Requirements.
