Windows 10: Running Code coverage in an UWP application

Hi, We are working on a UWP application. The application works just fine. We have included a unit test app universal windows and have written few testcases. The testcases are executed successfully, but we are unable to view the code coverage details. In the code coverage tab, we see the below errorEmpty results generated: No binaries were instrumented. Make sure the tests ran, required binaries were loaded, had matching symbol files, and were not excluded through custom settings.

[UWP] all UWP application windows are not displayed anymore after a lot of start/kill of any UWP application

Hello,

This issue seems linked to the Windows Anniversary Update (build 10.0.14393,
also reproduced on build 14905.rs_prerelease.160811-1739) and the new UWP lifecycle introduced with it, since this issue was not there before.

The test scenario is simple:

1. start any UWP application (in my example the windows calc.exe, the default Windows 10 calculator application)

2. wait 0.5 second

3. kill the same UWP application

4. repeat the 1-2-3 steps 5000 times

This scenario is basically reproducing an automated test environment.

The expected result is that the tested application will always be displayed correctly.

The actual result is that the tested application is not displayed anymore after a various number of loops (between 200 and 800). It looks like it is running in the background since the process can be seen in the task manager.

When the UWP application window can't be displayed, the scope of the issue is much more important: no UWP content can be displayed anymore (Edge browser or Windows settings, etc).

The way to recover from this is to log out from the user session and log in again.

Here is a python script to reproduce the issue:

Is it a known issue ? Any way to work around this (this is blocking our UWP automated testing environment)?

Mouse cursor not locked to crosshair in UWP applications

My mouse cursor isn't locked to my crosshair when I'm unpaused from Minecraft or other apps. I've tried reinstalling and resetting Minecraft, no good. Restarting my PC, no good.

Resetting UWP apps through Powershell seems to not work either;

Here's a short demonstration of the bug:

Such a mind boggling issue. Can't find a solution for this problem even on the internet.

Things I've tried that provided no solution:

• Resetting/Uninstalling Minecraft
• Reinstalling UWP apps to their defaults.
• Shutdown/Restarting my PC.
• Repairing my computer with SFC and DISM
• Repairing my PC with Windows Media Installation Tool (Upgrade PC Keep Files Option)
• Uninstalling/Reinstalling my mouse drivers.

I have tried recovering from a restore point and it seemed to fix the issue temporarily but the issue returned.
