VC访问EventLog的问题

[zrcat]

源代码：
#using <mscorlib.dll>
#using <System.dll>

using namespace System;
using namespace System::Diagnostics;
using namespace System::Threading;

int main(){
if(!EventLog::SourceExists(S"MySource")){
EventLog::CreateEventSource(S"MySource", S"MyNewLog");
Console::WriteLine(S"CreatingEventSource");
}

// Create an EventLog instance and assign its source.
EventLog* myLog = new EventLog();
myLog->Source = S"MySource";

// Write an informational entry to the event log.
myLog->WriteEntry(S"Writing to event log.");

}

提示错误：
atal error C1190: managed targeted code requires '#using <mscorlib.dll>' and '/clr' option

请高手指点！

看MSDN里C1190怎么解释
