OCCI + VS2010 + C++/CLI - help!

 I have a basic "prove you can connect" app written in C++ under VS2010 using a console app - it works.

The same code adapted to a C++/CLI Windows Forms app will not link.

#include <iostream>

#include <occi.h>

namespace oc = oracle::occi;

int main()

{

try

{

oc::Environment* env = oc::Environment::createEnvironment(); 

oc::Connection* conn = env->createConnection("user", "pword", "svr"); 

oc::Statement* stmt = conn->createStatement("select * from core.master_cmdy"); 

oc::ResultSet* res = stmt->executeQuery();

while(res->next())

{

std::cout << res->getString(1) << std::endl;

}

stmt->closeResultSet(res);

conn->terminateStatement(stmt);

env->terminateConnection(conn);

oc::Environment::terminateEnvironment(env);

}

catch(const oc::SQLException& e)
