I replaced all the images everywhere (by this I mean in drawable folders and all Windows Assets folders and iOS Resources folder), but it still shows me the default Xamarin icon for the app. I tried this code, too, but it doesn't seem to work either. Can someone tell me the solution?
[assembly: Application(Icon = "#drawable/icon")]
Updating Icon and Name (Android)
If you changed the icon file name please ensure you update the Icon reference in MainActivity.cs:
[Activity(Label = "MyName", Icon = "#mipmap/myicon", Theme = "#style/MainTheme"]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
}
You should also update the names of icon.xml and icon_round.xml in the mipmap-anydpi folder to match to new icon name. If launcher-foreground.png was renamed then update the value of <foreground...> in corresponding icon.xml.
Summary (Android)
Replace the png's in mipmap folders with your new icon
If name was changed, update Icon value in MainActivity.cs
If name was changed, update name of (or create a new copy of) icon.xml and icon_round.xml
If name of launcher-foreground.png was changed then update value in icon.xml. Eg:
<adaptive-icon xmlns:android="http://schemas.android.com/apk/res/android">
<background android:drawable="#color/my_launcher_background"/>
<foreground android:drawable="#mipmap/my_launcher_foreground"/>
</adaptive-icon>
If name wasn't changed and you've cleaned and re-built project but still your new icons are not deploying: Delete obj folder from Android project directory
Details and Issues if not updating (Android)
Xamarin Forms/Android puts 2 icons in each mipmap folder (mipmap-mdpi, mipmap-hdpi, mipmap-xhdpi, etc) - icon.png and launcher-foreground.png.
Replace both these images in each of the mipmap folders. I kept the same names but it should be possible to use a different name.
If you rename launcher-foreground.png then you must update the values in icon.xml and icon_round.xml (or their equivalent new names). The value in the <foreground...> tag references the icon/png. So, if launcher-foreground.png was updated to my_launcher-foreground.png this should be reflected in the icon.xml (see step 4 in summary above).
If the icons still don't update even after cleaning/re-building it could be that the original/default icons still existed in the Android project obj folder. The solution is to delete the obj folder from the Android project directory.
iOS
For iOS, please see Managing Icons with Asset Catalogs. A summary taken from the linked page is provided below:
For icons, a special AppIcon image set can be added to the Assets.xcassets file in the app's project.
To use an Asset Catalog, do the following:
Double-click the Info.plist file in the Solution Explorer.
Click on the Visual Assets tab and click on the Use Asset Catalog button under App Icons.
From the Solution Explorer, expand the Asset Catalog folder.
Double-click the Media file to open it in the editor.
Under the Properties Explorer the developer can select the different types and sizes of icons required.
Click on given icon type and select an image file for the required type/size.
Click the Open button to include the image in the project and set it in the xcasset.
MacOs
The guide for MacOs is Application icon for Xamarin.Mac apps. You need to consider the following steps:
Required image sizes and filenames
Packaging the icon resources
Using the icon
detailed in the linked docs above.
For Android try to set the icon app like this:
[Activity(Icon = "#drawable/icon")]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
{
.....
}
Make sure that you have changed all the icon images on all drawable folders ( drawable, drawable-hdpi, drawable-xhdpi and drawable-xxhdpi ).
For iOS I like set the app icons and splash screen with Asset Catalogs, here you can find a guide to how to use it:
https://developer.xamarin.com/guides/ios/application_fundamentals/working_with_images/app-icons/
For iOS in visual studio...
Step1: Generate all the app icons from https://appicon.co/
Step2: In solution explorer, under iOS project, expand 'Asset Catalogs' and double click on 'Assests'. You can change the existing 'AppIcon' icons or Add a new Asset and attach the icons.
This is how you add a new asset...
Step3: In solution explorer, under iOS project, double click on Info.plist.
Go to 'Visual Assets' tab, click on 'App Icons' and change the 'Source' to the
asset that you just created.
Done.
Hope this helps someone!
Answer is deprecated
If I understood you correctly, for iOS project: Properties -> iOS Application
For Android: Properties -> Android Manifest
I had the same problem, but the following helped resolve it:
Go to MainActivity.cs (in the Solution Explorer)
Look for where it says 'Icon ='
Change the location of the Icon, but don't include the extension, i.e. jpg, png, etc. (For ex. Icon = "#drawable/weatherIcon")
Save the file
Restart debugging (the little restart icon beside the stop and pause icon around the top right-hand side of your screen)
If you get stuck on any part of this check out this short video from 02:47 onwards https://youtu.be/5g8lWPQZFxs?t=167. It helped me a lot.
Try to replace all the icon on iOS project > Properties > iOS Application > Iphone Icons/IPad Icons.
I change all of them, the settings icon do change. Images that on Resouces can be created by just insert images on there.
Tested this today and noticed that you only need to change the icon images in all drawable folders,
drawable,
drawable-hdpi,
drawable-xhdpi
drawable-xxhdpi.
Depending on the device it's going to use different images. For me i used "Visual Studio Android Emulator" using:
- 5" KitKat(4,4) XXHDPI Phone (Android 4,4 - API 19)
Did not need to uninstall and reinstall the app in the emulator, it updated on it's own after starting the project with "build" checked in the menu Build/Configuration manager.
On top of that no code changes were made!
If you replace the Icon.png and still nothing changed on the device, than change "Copy to Output Directory" propertiy to "Copy if newer" or "Copy always".
That was my solution.
All of these solutions are great, but
THE SIMPLEST WAY:
You can now just use ResizetizerNT's nuget package and upload one svg file and set IsAppIcon to true. That should generate everything needed.
If the existing app icon is icon.png, just name the svg to icon.svg and it should automatically work.
Alternatively, you can also add another SVG for the background in order to support adaptive icons on Android.
Context: ResizetizerNT was created by the Xamarin.Forms/MAUI Engineering Manager, Jonathan Dick

I've created a WinForm application with .NET 4.6.1 and C#. I'm using Visual Studio 2017, with latest fixes updated (up to 29-Sept-2018).
The application uses a custom icon, and it's correctly shown: exe file is displayed with the proper icon.
I've created an Installer Project using the "Microsoft Visual Studio 2017 Installer Projects" extension. The installer copies sets of files in different locations (under Program Files, under the user's App Data, etc), and the files are correctly copied. EXE files correctly display the custom icon I've set.
Now, here comes the problem.
I've set a shortcut on the desktop.
The shortcut is created and actually works, but the icon is wrong: the default windows icon is shown instead.
I've tried several solutions and read from several forums.
1- I've tried to "Create New Shortcut" from the File System view (Desktop folder), and then set the Icon from the Properties window.
2- I've tried to right-click the output exe and select "Create a shortcut to primary output", and then dragged the shortcut to the desktop folder.
3- I've tried to select the icon referencing directly the Application Output exe: the wizard allows me to select the correct icon, I select it and confirm.
4- I've tried to select the icon referencing the source ICO file: once again, the wizard allows me to select the correct icon, I select it and confirm.
Any solution I've tried, I ALWAYS obtain a shortcut displayed with the default icon and NOT with the custom icon.
Whatsmore, if I try to manually "Create a shortcut" by right-clicking on the EXE, in window's File Explorer, the shortcut is created using the correct custom icon! So, it's strange that Visual Studio (or the installer) is not able to do the same thing during the installation.
Do you have any idea of the cause of the problem, and how to fix it?
Thanks!
I had the same issue, and tried every combination the OP also tried.
In the end my issue was down to the fact my .ICO file did not have the correctly sized images for the desktop shortcut. (It would have been nice if Visual Studio had told me that!!!!)
Oddly like the OP generating a shortcut by hand did make the icon appear, so I find the above a bit strange!
Anyway I was generating my .ICO file using GIMP to convert a PNG. I had clearly got this stage wrong.
I'd suggest trying a different .ICO file first and see if that is the cause.
It was for me and I solved it by using the following site:
http://icoconvert.com/
I then ticked the relevant boxes for the sizes, used this new .ICO file and hey presto it all works
I'd the same problem.
I had fix it simply select the main ouput (.exe) and not the .ico in the shortcut property icon option. I suppose installer not recognize the .ico file correctly.
I encountered the same problem. Just ensure you set the icon for the project to the same icon file as for the desktop shortcut and user program shortcut.
The icon file must follow the dimensions of Windows 7.
You can use http://icoconvert.com/ for changing the icon dimensions.
I had the same problem, using VS 2019 with the Visual Studio Installer extension.
I checked my icon had the correct dimensions (16x16, 32x32 and 48x48 within the ICO file), so it wasn't this.
Also, I had previously installed the app and the icon had worked fine. I'm using the "replace previous version", but I'm not sure if this is cause.
I double-checked the installers Outputs, and yes, the .ico was being copied/included... however I found that the defined shortcut (in VSI editor) did not have the icon property defined anymore - it had reverted to "(None)".
1
I resolved it in VSI, by using the Properties window for the shortcut, on the Icon property, select Browse from the DDL, then set the .ico from the source file. (The VSI detail tab still shows the default "text doc" icon, but result after install is the one I wanted/selected).
This is not the first time VSI has done this to my projects, so I'm guessing it is a slight bug of this otherwise great extension.
The problem for me was that the .ico was compressed with PNG.
Do not export using Vista PNG compression! Use normal BMP frames instead.
Yes I did my homework first. And I'm still stuck. First let me express my irritation at Microsoft for deprecating the Installer project type. Shame on them.
Back to my issue, Here is the error:
Error 3 -3204: Cannot extract icon with index 0 from file <some_path>\obj\Debug\MyProject.Gui.exe.
Attempt #1: InstallShield: cannot extract icon with index 0 vb.net
-- The answer says to include an object of type icon in my exe and rebuild. To do this, I tried the following:
right clicked on my windows forms project, add new item, icon, save all
open the icon file in step 1, draw some text in it, save all
right click the project and select rebuild (no errors, looks good)
left click on 'Specify Application Data'->'Files', select the *.ico in the project (Note: I can see it clearly listed, and it appears in the dialog as index0)
left click on 'General Information'-> 'Display Icon' -> browse for the *.ico (located in project folder for MyProject.Gui.exe)
save all and rebuild all
...I still get the same error message.
How does one "Recompile your EXE to include an icon and the message will go away"?
I had the same issue. Your problem is because you need to embed the icon into your executable. The way you do this is in Project Properties window in Visual Studio (Alt-Enter or right click ->properties for project root in solution explorer).
In the project properties under Application, there's a group box called Resources. Add your icon as shown below and install shield will build fine.
Hope that helps.
I was getting this problem, I try a lot of solutions on the web, but the only way that works for me:
Expand the deploy solution (+) on the right panel (Solution Explorer)
Expand the menu "Configure the target system"
Double click on Shortcuts folder
Here you will find 2 output you set up in the project wizard.
Select one of them, and find the property Icon, click to (...) to browse the propertly icon.
Do the same with the second one output built solution.
Rebuild your project!
Regards,
You need to copy the icon file to the debug folder of your windows application to successfully compile.
Go to Shortcuts/Folders under configure the Target System.
Select your application from the tree.
Select the icon and change the index to 2 (or something other than 0)
Build it.
If the problem is that you associated the icon with the installer and you embedded it into your application but you are still getting this error, try adding a folder exception to your antivirus software. The exception should be the folder where your source is located and the executable is output.
The symptom is that you randomly get this error during a build. It is caused by your antivirus software preventing the installshield icon extractor from accessing your application executable.
This happened with me also. My application runs in the background so I didn't create an Icon for it. When this error occurred I assigned an icon and everything built okay.

If you want to play along, you can create a Visual Studio project named NaiveTextMovement
and add the 14-point Segoe UI Mono font to the Content directory. The fields in the Game1
class are defined like so: "
how to add 14-point Segoe UI Mono font to the Content directory?
iv tried creating a folder in the solution and placing the font in it then i try to load it using Content.Load ... but it doesnt work. how is that?
You need to create a content project, then create a font description file. Reference the content project from your main XNA project.
In fact, a content project should already have been generated for you.
The font description file is an XML file. Editing it will be self-explanatory once you open it, as it will be auto-generated and well-commented.
When you create a new Windows Phone 7 game project, the template creates two different projects in your solution. One is the WindowsPhoneGame project and the other is the WindowsPhoneGameContent project.
The Game project is where you'll be adding all your code and the Content project is where you'll be adding all your game assets like sprites, textures and spritefonts.
You can see in the image below the two projects shown in the Solution Explorer (that's the pane in the upper right if you have the default configuration for Visual Studio).
The "Content" project is the one highlighted in the above image.
To add a SpriteFont, simple right click on the Content project and select "Add" and then "New Item" from the Add menu. This will open up the below dialog.
From the "Add New Item" dialog, simply select SpriteFont and give it the name you want. That will add a new SpriteFont object to your Content project and to your game.
I have a small app with a setup project.
If I create a shortcut to my Primary Output, then this gets a standard Win7 icon and not the icon specified in my exe's Application Icon?
Whats the best way to make sure my desktop shortcut icon is the same icon as my exe?
e.g. If I change the exe's icon then I'd like the Setup icon to change as well.
If you set the icon for the shortcut you can set a primary output as source. In the file system editor of the setup project, click on the "(Icon)" combobox in the properties pane of the shortcut, then option "(Browse...)", button "Browse...". You'll see this:
Then add output and select the primary output of the exe.
You can add an icon from your target.exe file to the shortcut... in File System On Target Machine, browse to the shortcut in the folder you want to add the icon to (User's Desktop,etc). Right click the shortcut and select Properties Window. You'll see an Icon line... click it, select Browse, then browse to Application Folder/yourExe.exe (change from ICON to Exe files) and say OK. It will show you the icon from yourExe.exe that it has selected, say OK. You basically have to do the same thing for your Add/Remove Icon (appears in Control Panel/Uninstall)... properties page for your setup project. You have to do it for all shortcuts in different folders (User's Desktop, User's Startup, etc.) All icons good now!
To add to Gert's answer: make sure you build your project first. Otherwise the setup app will not see the icon.
Very simple way using IWshShortcut (works in .net 2 too):
WshRuntimeLibrary.IWshShortcut MyShortcut = (IWshRuntimeLibrary.IWshShortcut)WshShell.CreateShortcut(fullPathLnk);
string iconLoc = MyShortcut.IconLocation; // <- example: "c:\icon.ico,0"
I use to check if iconLoc still exists, fix if not, you can use to find and read icon file, etc etc
I changed my Application's icon for a new one, by going to: "Project/MyProject Properties/Icon and Manifiest", and load the new icon. Now, in my debug folder the icon of my .exe file appear with the new icon, which is ok, but when I execute the .exe, the application icon in the taskbar still showing the old one.
Please advice.
You have two place to change your icon.
First place
The first place is in the project.
Right click on the project
Select Property
Go in Application Tabs
Choose Icon and Manifest and select the icon you want
Second place
The second place is in the property of your Winform.
Open the Form
Click on the Form
Press F4 or go in the property of the Form
Go down in the property to find "Icon"
Select the icon you want.
The reason you have a different icon in the taskbar than your application (.exe) icon is that the taskbar use the current form icon to display in the taskbar.
After encountering the same problem, I resolved it by doing the following:
Just stop your explorer.exe from task manager and rerun the explorer.exe again.
As a commenter mentioned, you should set in the properties of the *.ico file: Copy to Output Dir: Copy if newer.
This property is not absolutely required. I developed a winform application and tested it without icon. Then I created and added the icon. The icon showed when running with the VS debugger. I copied the bin/debug directory to another pc and there it ran with showing the icon.
But the icon did not show on the development machine when the app started by clicking the *.exe file.
Logout/login windows did not cure this.
Change the Copy To Output Dir property on the icon file to Copy If Newer, and rebuild the application, did help. Now I can start the app by clicking the *.exe and the icon shows nicely.
Conclusion:
It is not always required to build the app with the icon file copied to the output directory, but with this measure you will increase your chances.
Make sure that your *.ico file contains an icon of the proper size (like 16x16 for small task bars).
Copy your new icon in Project Properties --> resources --> icons
In your Main_Load function add:
this.Icon = Properties.Resources.newIcon;
Check this out for icon information and sizes it supports. Assuming this is just a simple error that you are getting check if your ico's are as per what is specified here http://msdn.microsoft.com/en-us/library/ms997636.aspx
I had the same problem and none of the above solved it.
In my case, I had defined the icon different for two different langages (default language english and german). You can see this if there appear two resources files: FormX.resx and FormX.de.resx
With the accepted answer only default icon was changed. But when running the application on my pc the german icon was used.
So I had to change the icon for both resources. In Visual Studio you can change the current resource language by switching the language item (in the forms properties) from default to another language.
I had the same problem. The "first place" mentioned by Patrick is about the file icon, i.e. the .exe aspect. The "second place" is about the form (in the upper left corner).
Restarting windows file explorer seemed to be a satisfactory solution too. But all this didn't work today. I didn't restart the computer, by the way.
This is what really displayed the new icon in the task bar: I realized that there was an old shortcut of the .exe on the desktop. Deleting the shortcut did the job.
