Windows Phone app's icon not changing - visual-studio

I am extremely close to publishing my Windows Phone app. However, even though I changed the ApplicationIcon and Background images, the Windows Phone emulator doesn't use them.
Any ideas of why this is not working?

Try uninstalling your app from the emulator then stop and restart it before finally deploying again. Seems to get cached sometimes.

Well, I figured it out.
I needed to unpin the app from the Start screen, then repin it.
Hope this helps someone.

What is the reason for xamarin app style change?

I'm from Ukraine, so I immediately apologize for my crooked English. I got one very incomprehensible problem with which I can not figure it out. I have created a mobile application for Android and IOS. Absolutely normal application. I tested it on the emulator on several phones. But on one of them, the app didn't look like itself. For some reason it became dark and looked strange (I attached the screenshots). The normal version is white-green, this version was dark. I can't figure out what is the reason. Immediately I will say that the phone is normal and the light theme is enabled on it, the phone has standard settings. And everything else on this phone except this application is displayed normally. Please tell me what is the reason
I tried to change the themes and settings of the phone, and found out that the problem is definitely not in them

Windows Phone 8.1: App crashes in fast app switcher when not attached to debugger

I have been developing this app for quite a long time, and have had little or no issues. But when I decided to test it without the debugger attached, it caused problems with the fast app switcher. Whenever I switch the app with fast app switcher (or by pressing Start button), it causes the app to crash.
I am using VS2015 and tried enabling break for all exceptions, but still nothing happens while debugging, so I can't understand what the actual problem is.
Any ideas how can I solve this??
P.S. There seem to be a solution for this in this thread: Fast App Resume crashing on WP8.1 when not attached to debugger, but it is intended for Windows Phone 8 and doesn't match with the 8.1 api. Any similar solutions for WP8.1??
have you tried to implement the NavigationHelpers in your app ?

Windows 8.1 Task Bar Context Menu Error

I'm sorry if this is the wrong place but I really don't know where to go for something like this.
I did a fresh install of Windows 8.1 on my new SSD and the context menus for the task bar looks like this now...
I realize this may not be the right place to post, but could you point me in the right direction? Thanks!
The solution was to uninstall Windows Update KB3072318.

You get this graphical glitch because you use a custom Windows 8 theme under Windows 8.1. Microsoft changed the format a bit. StartIsBack+ (for Windows 8.1) fixes this issue and restore the Win7 Start menu for a better Windows 8.1 UX.
Ok, forget my previous answer! It's got nothing to do with the SSD.
I just found a fix/workaround:
Just make a clean install with the internet completely disconnected and only connect after the setup is fully finished.
Also, this way, you won't even see the windows 10 upgrade notification on the setup.
Hope this helps...

The parameter is incorrect exception

I'm working on a Windows Phone 7.1 project and got most of my work done and decided to add to the project the images for my tiles (62x62 and 173x173 PNGs) plus the JPG file for the splash screen (SplashScreenImage.jpg 480x800).
Before adding these images to the project my project was running fine! After adding them and setting the tiles images to the 2 new files, my project still builds ok, but when running on the 7.1 simulator (my acer laptop doesn't have hardware assisted virtualization enabled in order to run the wp8 emulator) the app crashes when trying to load MainPage with "The parameter is incorrect" exception (in the Application_UnhandledException handler).
I've been trying to find a solution on the web for the last 1-2 days, found few mentions of this error and few possible causes, but none of my findings helped so far. The exception doesn't say anything helpful and it's getting really frustrating considering that most of the serious work is done and I'm very close to releasing the app to the marketplace.
Did anybody run into this issue before? Any ideas what could have gone wrong and how I could solve this exception? Any help is much appreciated!
Thank you in advance!

Whenever I wish to change the Splashscreen and other images, here is what I do:
Locate the file on disk using Windows Explorer.
Open the file using some image editor (I use Paint.NET)
Remove the default image and replace with your image maintaining the dimensions.
Save the image and return to Visual Studio.
Rebuild the entire project.
This works seamlessly without any errors. ;)

How to fix "Unable to activate Windows Tailored application" on Win8

I get "Unable to activate Windows Tailored application" error in Metro app when I'm running it under debugger of Visual Studio 11. I installed Windows 8 x64 Developer Preview on my Dell E6510 laptop.
I googled it and found out many people saying it happens when screen resolution is smaller than 800x600 but it's 1920x1280 in my case.
The app itself contains nothing. It's just empty wizard created application which is nothing but windows with black background.
Any ideas? It seems like very common issue.
The solution was quite bizarre but I figured it out.
It turns out not a single Metro application works under Administrator account including my apps. I'm talking about built-in Administrator account that is disabled by default (but which I enabled).
It gives "Access denied" error so I suspect it's somehow related to the way WinRT COM objects were registered or something like that. Go figure.
I hope somebody from Microsoft is reading this.
Best solution is to wait 2 weeks for the next release. The developer preview is full of fun bugs like this. I've seen this error caused by invalid app.xaml. Double check that you really haven't changed anything. I've also seen this error sometimes resolved by rebooting. Have fun!
