UWP Windows-10 WACK tests Errors

Question

I am new to Windows app development. I have built a C# app targeting, Windows 10 desktop & mobile platforms. My C# app calls into Windows Runtime Component written in C++ (c++/cx).

I followed this MSDN Link to run WACK test.

I have Windows App Certification Kit 10.0 installed on my machine. To run the test, I do Validate Store App -> Select my app from list of installed apps on the machine. My app is installed in release mode. When I run WACK test, Supported API test fails with following:

On further googling, I found these Link-1 and Link-2

The possible solution in the above links is to uninstall KB 2976978 update & rerun WACK tests MS Support Error Link
My machine doesnt seem to have this KB 2976978 update though.
Control Panel\Programs\Programs and Features View Installed Updates or Search Installed Updates doesnt seem to find the above update.
I have checked this: SO post As mentioned in this SO post even in my case everything compiles fine with /ZW /EHsc /D flags
My VS details are:

MS Visual Studio Professional 2015 

Version 14.0.25123.00 Update 2 

MS .NET Framework 

Version 4.6.01038

Any help will be highly appreciated.

Answer 1

The problem was that, my C++ native lib was referencing Desktop CRT dll's(vccorlib140.dll) instead of store CRT dll(vccorlib140_app.dll).

The app was referencing Desktop CRT because, I was linking my app with libs from this location:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\lib

Turns out to build a store app we need to reference libs from this location:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\lib\store
