Question

这是我的代码：

// wrl-consume-component.cpp

// compile with: runtimeobject.lib
#include <Windows.Foundation.h>
#include <wrl\wrappers\corewrappers.h>
#include <wrl\client.h>
#include <stdio.h>
#include <windows.networking.vpn.h>

using namespace ABI::Windows::Foundation;
using namespace ABI::Windows::Networking::Vpn;
using namespace Microsoft::WRL;
using namespace Microsoft::WRL::Wrappers;

// Prints an error string for the provided source code line and HRESULT
// value and returns the HRESULT value as an int.
int PrintError(unsigned int line, HRESULT hr)
{
    wprintf_s(L"ERROR: Line:%d HRESULT: 0x%X\n", line, hr);
    return hr;
}

int wmain()
{
    // Initialize the Windows Runtime.
    RoInitializeWrapper initialize(RO_INIT_MULTITHREADED);
    if (FAILED(initialize))
    {
        return PrintError(__LINE__, initialize);
    }

    // Get the activation factory for the IUriRuntimeClass interface.
    ComPtr<VpnManagementAgent> uriFactory;
    HRESULT hr = GetActivationFactory(HStringReference(RuntimeClass_Windows_Networking_Vpn_VpnManagementAgent).Get(), &uriFactory);
    if (FAILED(hr))
    {
        return PrintError(__LINE__, hr);
    }

//    VpnManagementAgent vpn;
auto profiles = uriFactory->GetProfilesAsync().get();
wprintf(L"Found %d profiles\n", profiles.Size());
for (auto vp : profiles)
{
    wprintf(L"Found profile %s\n", vp.ProfileName().c_str());
}}
/*
Output:
Domain name: microsoft.com
*/

基本上是从msdn复制粘贴内容和该question的答案。

我正在这样编译： cl /diagnostics:column wrl-consume-component.cpp /link RuntimeObject.lib windows.networking.lib

很明显，我在这里错过了很多东西。

错误消息是：

wrl-consume-component.cpp(40,27): error C2027: use of undefined type 'ABI::Windows::Networking::Vpn::VpnManagementAgent'

错误C2079使用未定义的类-WinRT / UWP？
