Return Value

HRESULT Description
S_OK SetAppDomainManager returned successfully.
HOST_E_CLRNOTAVAILABLE The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.


The AppDomainManager provides the host with a mechanism to bootstrap into managed code and to control the creation and settings of each AppDomain. The AppDomainManager is loaded into each AppDomain when that AppDomain is created. If it chooses, the CLR notifies the host that the application domain has been created by setting the value of the pUnkAppDomainManager parameter.

In its implementation of the SetAppDomainManager method, the host can set the assembly name and type for the application domain manager.
