.NET Framework 4.5
ICLRRuntimeHost::Start Method

Initializes the common language runtime (CLR) into a process.

HRESULT Start();
Return Value

HRESULT

Description

S_OK

Start returned successfully.

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.

Remarks

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.
