WACK Error after Converting WPF to UWP using Desktop App Converter

I was trying to convert my awesome WPF app to UWP using the Desktop App Converter. I converted the app using DesktopAppConverter successfully, installed on my local Windows 10 machine and works like a charm. All good so far.

However when I tried the Windows App Certification process, it fails with the below error.

• API _amsg_exit in msvcr100.dll is not supported for this application type.
• API _cexit in msvcr100.dll is not supported for this application type.
• API _commode in msvcr100.dll is not supported for this application type.

I actually use many essential functionalities via a CPP library which was created using some python code (which I don't have source code for).

(I guess "msvcr100.dll" is Microsoft C++ Re-distributable Package? )

Can any one help resolve this issue?

The WACK tool in the Windows 10 AU SDK is not applicable to Desktop Bridge app. You don't need to run it prior to submission. The error you are seeing here you can ignore.

Upcoming new versions of the SDK will have an updated WACK tool with specific support for Desktop Bridge apps.

Thanks!
