My app icon is not visible in share menu windows 10 - UWP - c#

Icon is not being displayed in Share menu next to my app name. But its displayed correctly in icon
I have added icons to all the options in visual studio

The assets you are using are right. At first, I didn't see any problem when I used RTM OS version (Version 1511, OS Build 10586.494). However, from your screenshot, it seems you are using Insider Preview Build. So I tested it again on Windows 10 Insider Preview Build 14393 and I can reproduce your issue.
Actually, your app icon is not invisible. It seems that System has cached the app icon used in Share menu when your app is deployed for the first time. After this, even we reset the app icon and redeploy the app, the icon in Share menu still won't change. I guess you've run your app with the default assets before you set your own assets. So in Share menu, it still use the default icon, but in Start panel, it is correct. You can created a new project with your own assets and then run this new project, you icon should be able to display in Share menu correctly.
This issue seems only affect Insider Preview Build. For Insider Preview issues, please feel free to share feedbacks with Microsoft. You can report this issue with Windows Feedback app. Your feedback has made Windows better!

All Logos Related to UWP are stored in Package.appxmanifest. Edit it using an xml editor. See if there is any image that is still a default icon.

Android emulator in Xamarin Visual Studio does not show the app

I made a new Xamarin Project in Visual Studio , I chose the Single View App .
Then I did not make any changes.
I just pressed the Run Button.
The emulator started ,
but the app was not appeared in the menu of the phone of the emulator.
Is there anyone who know what cause the problem?
On Windows you have a couple of options to accelerate the Emulator. Read more here: https://learn.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/hardware-acceleration?pivots=windows
Using HyperV: Make sure to install the Windows Hypervisor Platform:
Right click on the Windows button and select ‘Apps and Features’.
Select Programs and Features on the right under related settings.
Select Turn Windows Features on or off.
Select Hyper-V and click OK.
You probably need to restart your computer after.
Intel HAXM: If you are not using HyperV and don't intend and don't run other hypervisors such as VMWare, VirtualBox etc. then you can install Intel HAXM.
In the Android SDK manager, in tools, download Intel HAXM. After that is done, go to the folder where the Android SDK is installed. There should be an extras folder where there will be an installer for Intel HAXM.
On macOS, Intel HAXM is the way to go. Read how to install it here: https://learn.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/hardware-acceleration?pivots=macos
Should be as easy as running sh ~/Library/Developer/Xamarin/android-sdk-macosx/extras/intel/Hardware_Accelerated_Execution_Manager/silent_install.sh from a command-line.
Either of these approaches should significantly speed up the Android Emulator.
If you have issues deloying to the emulator, sometimes the default configurations have very limited space and installing anything may fail due to the emulator running out of storage. Go to the Android AVD and increase the internal storage size.
For other failures, check the Deploy Output window in Visual Studio and provide more information of what is going wrong. Otherwise it is just a guess.
This might be just a bug. Create a new project. If still blank wait 5 minutes. Maybe your computer is slow so it takes time to load.
If you start using xamarin for the first time
Create device from dropout menu (don't just let it create it from pressing run button).
Select device from dropout menu.
Run up.
if it didn't added just restart Visual Studio (should change "Run" into name of the device)

UWP Scenario - Is there a way to have a UWP app on the same computer both from the Store and from Visual Studio at the same time?

My question is really simple: I’m a UWP developer and I developed some UWP app for the Win Store.
The problem is that I would want to use these apps on my own too, but I can’t, because I have to have deployed version from Visual Studio for testing new features and new versions.
To the point... is there a way, for an own UWP app, to have both “Store” and deployed version of it, right on the same PC with the same user?
For your scenario, we could make a project copy, and regard the copy as developer type, open the project with Visual Studio and double click Package.appxmanifest file then find Packaging tab option modify the package name to another. click the Local Machine button. You will find the new app in the start menu and the app will not override the store version.

ClickOnce app icon didn't update in some cases

I help maintain a WPF application deployed via ClickOnce. When I first installed it, we were using Icon #1 as our app icon (specified by clicking Properties on the Project and setting the "Icon" field); this is the icon that shows up as the Desktop shortcut.
Recently our company's logo changed so I updated the icon to Icon #2 and deployed a new release to the ClickOnce server. On some of the computers running the software, upon receiving the updated release, the icon changed as expected. However, on a few, the old icon is still showing, even though I can see the program has updated to the latest version deployed in ClickOnce.
Why is this? Has anyone else encountered this? And what can I do to fix it? By the way, the program is self-signed; not sure if that makes a difference.

XAML layout changes not updating on build

I have a Windows Phone 8 project that I am working on in VS2012.
Its been doing this for a while, but I haven't got to the bottom of it.
If you make any changes to the XAML, like moving a grid, and then deploy it to the phone.
But the changes are not applied when the viewing the app on the phone, the grid hasnt moved. The only way to apply it, it is uninstall the app from the phone and deploy again, or delete the 'Release' folder which it has built and build again.
C# code changes are deployed ok though.
Does the project name contain (or the folder it is in) any spaces?
In my case, removing spaces solved the problem.

Change Windows Forms application icon in Add/Remove Programs

I have one Windows Forms application, and I deployed that using ClickOnce. I changed the project icon. After publishing and installing, that icon is appearing on the desktop. That much is OK.
But when I search that application in Add/Remove programs in the control panel, it shows one default icon and not mine. How can I change that icon or is it not possible?
According to the thread in the MSDN forum, Missing Icon in Add/Remove Programs for ClickOnce Application, it seems to be possible.
I'm pretty sure ClickOnce does not give you ability to change the icon. I use Visual Studio Setup Project in my deployment, and if you go to the Properties, the first one is 'AddRemoveProgramsIcon', where you can specify what icon you want to be used there.
