UWP Tile Text Color - winrt-xaml

I am trying to set the text color on my UWP app's primary Start Menu tile so that it is black. (I am doing this because my app's icon calls for a white background, and you cannot see white text on a white background.) I found the answer to this question, but it discusses Windows 8 apps, and the UI described in the answer does not seem to exist anymore when developing for Windows 10. Does anyone know how to do this on a Windows 10 UWP app?

The way of doing this in a UWP app has changed slightly. Set the ForegroundText attribute to "dark" in the VisualElements node.

How to create a taskbar application similar to Touch Keyboard on Windows 8.1?

On Windows 8.1, if you right-click on the taskbar and point to Toolbars you can turn on Touch Keyboard, which makes a small image of a keyboard appear at the far right of the task bar just to the left of the notification area.
I want to develop an application that can make a presence here with a dynamically updating display of a time string (a count down application).
Can anyone advise if this is possible using C# .NET?
From various research I've discovered it is extremely difficult to determine exactly what Microsoft refer to this utility as. I have seen 'deskbar', 'deskband' and obviously it's under 'toolbars' in the task bar context menu. It also seems every major OS release changes the terminology and functionality completely. So bonus points if anyone can clear up what it's called on Windows 8.1 in addition to what term to research or MSDN article to read about developing an application that sits there.

Xamarin iOS Black screen only after update UnifiedAPI. apparently all resources not loading

After migrate Xamarin iOS project to Unified API, the app shows black screen only.
Apparently all resources are not loaded at all.
Not only all images including icon, splash are not loaded, but also all XIBs are not loaded.
Now only default black window screen is shown.
Any advice to solve this?
In some cases XI 8.6.0 new msbuild-based build system can forget to copy some files into the app bundle.
This is fixed in the service release (8.6.1) which is in the alpha channel (right now). You might want to try it to see if this is the issue (if not then please file a bug report so it can be investigated).

Difference between Launcher and Theme in Android

I'm currently working on launcher based Android app,can any one tell me the difference between launcher vs theme(Which we usually downloaded from App Stores)?
theme is the general look of a phone's UI like the shape, size and color of icons the look of the menu, the background photo or color but the Launcher is an application itself a third-party user interface (UI) programs which take over the duties performed by the factory UI.

Universal App Windows Phone Orientation

Recently I was developing a Universal app for both the Windows Phone and Windows Store. In that app, I was trying to fix the Orientation of the App to Landscape. But in WinRT based apps of Windows Phone 8.1, I failed to find any Orientation option.
In the Silverlight apps, we can fix the Orientations as we want. But is there any way to fix the Orientation to Landscape mode in the Universal Apps?
It will be very helpful if someone help me in this regard. Thanks in advance. :)
Under WinRT you can have a look at DisplayInformation class, where you will find probably all you need.
You can also declare your supported rotations in Package.appxmanifest file in Supported rotations.
Here you can download an example of an App with three Pages, each with different orientation.

Opt-out from Supporting iPhone 5 Layout

This sounds to be a weird question, but I would like my App not to support iPhone 5 layout at this moment.
I know, to support iPhone 5 layout, I have to add a Default-568h#2x.png as Launch Image, then the XIB will be resized and supports iPhone 5.
The current issue is, the layout we currently have does not have iPhone 5 4-inch layout. If iPhone 5 4-inch layout is enabled, the buttons are disabled. After discussed with co-workers, we decide not to support iPhone 5 layout at this moment, i.e. we prefer to leave black borders on top & bottom of the App. Is it possible to submit an App without Default-568h#2x.png ?
Yes, that's possible. The Default-568h#2x.png is just a flag to trigger iPhone 5 support and we've successfully submitted fixes to Apps without adding the Default-568h#2x.png file. Apple will currently not reject your App update for not supporting iPhone 5.
Of course you should update the App over time and I would not be surprised that Apple will change this policy in the future, especially for new Apps. But for now you're okay!
