Using UWP APIs in Win32 C++ Apps RRS feed

  • Question

  • I am not sure if this is the correct forum to ask this question. I am aware that it is possible to use Universal APIs in Win32 apps using Universal API contract. I am tying to do a sample app service app based on the git.ie. a UWP app talking to Win32 c++ app  https://github.com/microsoft/DesktopBridgeToUWP-Samples/tree/master/Samples/AppServiceBridgeSample_C%2B%2B

    My question is ,it is sufficient to include the below locations in C++/General/Additional #using Directive  setting in the Win32 C++ app?

    $(SystemDrive)\Program Files (x86)\Windows Kits\10\References\Windows.Foundation.UniversalApiContract\
    $(SystemDrive)\Program Files (x86)\Windows Kits\10\UnionMetadata
    $(SystemDrive)\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcpackages
    $(SystemDrive)\Program Files (x86)\Windows Kits\10\References\Windows.Foundation.FoundationContract\

    I have all these installed in my system. Still I am getting error with the below includes/statements on the Win32 C++ side.

    #using <Windows.winmd>
    #include <iostream>
    #include <string>
    #include <ppltasks.h>
    #include <windows.h>
    #include <appmodel.h>

    using namespace concurrency;
    using namespace Platform;
    using namespace Windows::ApplicationModel::AppService;
    using namespace Windows::ApplicationModel::DataTransfer;
    using namespace Windows::Foundation;
    using namespace Windows::Foundation::Collections;

    fatal error C1190: managed targeted code requires a '/clr' option. But the Win32 C++ app in the original git sampel doesnt have clr support. How to fix this one?

  • Hi,

    If you try to turn on /clr support, will the same problem occur? And I notice that the original git sample set the /zw option, have you also set it? If these still don't fix the issue, can you please provide a simple sample for us to test?

    Best Regards,
