I am working on a Wpf desktop application, whenever i run my application it shows me a window and associated tab in the task bar(Normal windows feature). My problem is that the tab is using window's icon for unknown file-type, I tried with Icon property of Window, Icon gets assigned but still problem is when I run application, task bar Tab initially displays window's icon for unknown file-type and when window-load completes it changes to the Icon assigned. I want Icon there from beginning. Any help?
Edit:
I tried with .csproj --> Properties --> Application Tab --> Icon and set it to a .ico file. It works but I need to run my application by .exe file. It doesn't work in development environment(while running through visual studio). I need to set Start-Project option then. Is there any other way to solve this problem?
Check the properties of your main Window project.. You should be able to set an icon there.
Update: Is it such a problem that your icon does not show in debug mode? As long as it works when you deliver the program to your customer, its all alright, not?
On a side note: You could check some things though. Perhaps your icon is not included in your project, or it isnt copied when building to your Debug folder?
Update 2: You also need to set the Main Form's Icon for it to show in Debug. If you also set the icon for the main form, it will display in the Taskbar during Debug / Runtime.
I had a similar issue and google led me to this article. I forgot one simple thing, and that was my Main Form's Icon. If you also set the icon for the main form, it will display in the Taskbar during Debug / Runtime.
For WPF applications, use the attribute
Icon="Images\Logo.ico" for the Window element in XAML to have the window show the icon.
I know this is old, but I found that I could get the icon to show in the taskbar in Debug mode if I went to the project's properties and checked the "Enable native code debugging" box on the "Debug" page
That worked for me. In a VB application, go to Debug screen of Project options (of the UI project) and select Enable unmanaged code debugging. Not sure if there are any negative side effects, but it sure showed the icon during debug. Thanks.
This is old but you can also change the shortcut icon in the setup projet, this is what worked for me (when viewing file system by right clicking the setup project).
