HRESULT	Description
S_OK	`SwitchToTask` returned 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 host can switch in another task as desired or needed.

Note

SwitchToTask does not specify which task the host should switch to; it specifies only the task that it should switch from.
