error C2079 uses undefined class - WinRT/UWP? - c++

Question

So here is my code:
// 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:

It's basically copy paste from msdn and the answer to that question.
I'm compiling like this:
cl /diagnostics:column wrl-consume-component.cpp /link RuntimeObject.lib windows.networking.lib
Obviously I'm missing something huge here.
The error message is:
wrl-consume-component.cpp(40,27): error C2027: use of undefined type 'ABI::Windows::Networking::Vpn::VpnManagementAgent'
