Windows App Certification Kit hangs

Question

I have developed windows 10 App and uploaded that to windows store. However, I wanted to apply Windows Certification App Kit. The testing hangs during these two stages;

Direct3D trim after suspend In progress... UTF-8 file encoding In progress...

I don't use any of those features in my app, but I don't understand why it should hang during process?

Thank you!

I found solution for it. While running the test, simply un-check those tests which you haven't used in your desktop. — ARH, Dec 26 '15 at 04:14
Yes, I simply disable the 3D test as a workaround but sometimes I forget... :-( It would be better to have a solution instead... but at least it's working. — K232, Dec 26 '15 at 09:16
Same for me. "UTF-8 file encoding and" "Direct3D trim after suspend" hang and it is not possible to cancel the test. The only solution is to restart Visual Studio which is really annoying — pfedotovsky, Feb 29 '16 at 08:54

I ran into this exact same issue:

"Direct3D trim after suspend In progress... UTF-8 file encoding In progress..."

Problem was that I didn't try to run the Release Version locally first. It didn't run because I used preprocessor directives like so:

public static LicenseInformation licenseInformation = null;

...

#if DEBUG
        ...
        ...
        licenseInformation = CurrentAppSimulator.LicenseInformation;
#else
        licenseInformation = CurrentApp.LicenseInformation;
#endif

"CurrentApp" did cause an exception.. I use code like this now:

#if DEBUG
        ...
        ...
        licenseInformation = CurrentAppSimulator.LicenseInformation;
#else
        try
        {
            licenseInformation = CurrentApp.LicenseInformation;
        }
        catch (Exception)
        {
        } 
#endif

And when working with the licenseInformation somewhere I check if it is not null before I use it...

I also found some other issues (warnings) in my code by using "Run Code Analysis on Solution"..

So in my case it was a problem with my code.

WACK "Hangs" because it is waiting for the app to start.The problem occurs if you use packages that internally use native code. An example is SQLite (Written in C++).

SQLite for Universal Windows Platform requires this Directive to be included in Properties/Default.rd.xml. Otherwise the external code will throw exceptions when your app is run in native mode (Release build in Visual Studio).

<Type Name="System.Collections.ArrayList" Dynamic="Required All" />

For details about this directive and EntityFramework.Sqlite (EF7), see: https://docs.efproject.net/en/latest/platforms/uwp/getting-started.html
