Windows App Certification Kit 10.0.18999.0

Question

I'm getting this error when running Windows App Cert Kit 10.0.0.18362.1

Error Found: The supported APIs test detected the following errors:

• API __CxxFrameHandler4 in vcruntime140_1_app.dll is not supported for this application type. Microsoft.Graphics.Canvas.dll calls this API.

This is a provided answer:

"This is a false positive error.  This has been fixed in Windows App Certification Kit 10.0.18999.0 or greater.  You may ignore this error as the Windows store has been updated and will not report this error."

Where can I download this version of the WACK?  

The latest Windows 10 SDK does not include it.

Hi,

Currently, the official SDK download website only provides Windows 10 SDK 10.0.18362 which means the 18999 is not released. The new SDK could not be downloaded unless it is released.

Are you running the WACK test in local, right? If so, I'd suggest you upload the package to the store because it will run another online WACK test when you upload the package to the store.

Best regards.

Roy

I can confirm that this is still happening, in-case anyone else is coming across this issue recently or in the new year. Just happened to me on a project I haven't updated since 08/2019. Using the online WACK through submission worked fine whereas local WACK gave me this same error. 

Seems like we still need to wait for SDK 18999, but I haven't seen an update on when it'll be out. 

Anyways, good luck bug hunting! 

Answer 3

Still seeing this (Jan 16, 2020)

The fix is on the App store, so this error will not cause a submission to fail. 

It would be nice to get the new SDK so that the local certification test can pass and I don't need to dig through the results to see if anything else has failed.
