Initializes the common language runtime (CLR) into a process.
|HOST_E_CLRNOTAVAILABLE||The 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. If a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.|
In many scenarios it is not necessary to call
Start, because the runtime will initialize itself automatically upon the first request to run managed code. You can, however, use
Start to specify exactly when the runtime should be initialized.
