holy moly, you are on to something here.
Yesterday, as you know, I had somewhat of a setback because of two issues.
The Visual Studio one is now fixed and was my fault because I downloaded Visual Studio Express 2013 for Windows Desktop (I don't know what "that" is for but the "for Desktop" is not able to open our stuff.
The second issue is still ongoing.
I have a high-end MSI laptop with I use for mechanical engineering apps like SolidWorks.
To make W8.1 games, I bought an inexpensive ACER Aspire. It has 6GIG of RAM and a Intel 4600 GFX chip.
That GFX chip is customized which means that I can't just download an updated driver from Intel.
To make things worse, ACER doesn't have an updated driver available.
The reason why this is important is because I can't test my C2 games on that machine.
Every time I press the mouse or touch the screen, it flickers.
Some capx files I have downloaded from this forum flicker right upon opening the app in a browser.
I would like to send "a" version of my piano app to Microsoft and then update it on a bi-weekly basis.
The play-back function would lift this app up several notches and is a "must add" feature for sure.
Let's think about this and in the meantime, I will try to tweak the app and sometime this evening, send it to Microsoft.
Let's hope it works on their end and they approve it.
