How To Create an Icon for Visual Studio with just MSPaint and Visual Studio

Creating an icon in MSPaint works just fine. Here's how you should proceed to get it to work.

In Visual Studio

• Open Resources.resx from Solution Explorer (it's in the Properties folder)

• Choose Icons from DropDown Menu on the left [Ctrl+3]

• Choose Add New Icon from the DropDown Menu Add Resource

• Enter a name for the Icon Resource file

• Right click on all the icons in the left panel - one at a time - and choose Delete Image Type (The last icon cannot be deleted - Leave it for now)

In MSPaint or an image program of your choise (I prefer Microsoft Paint 3D)

• Create/Open the image that you would like to use (It could be a screenshot of your program)

• Resize the image to 256x256 pixels

• Select the full image [Ctrl+A] and then copy the image [Ctrl+C]

In Visual Studio

• Right click in the left panel (the icon panel) and choose New Image Type... [Ins]

• Choose Target Image Type 256x256, 24 bit

• (Select the New Target Type and) Paste [Ctrl+V] the image you copied from your image program

In your image program and in Visual Studio

• Repeat the above Image Copy (image program) and Target Paste (Visual Studio) process for the 24 bit icon size's 128x128, 64x64, 32x32 and 16x16 (and/or the ones you like to support)

• Don't forget to delete the last icon you couldn't delete before

In Visual Studio

• Save the icon file (.ico) (by closing its tab or using [Ctrl+S])

• Add the icon to your forms

• Right click your project file in the Solution Explorer and choose Properties
  (You'll also find it in the Visual Studio Menu Debug -> "Your Project Name" Properties...)

• Choose the Application section

• Under Resources - Icon and manifest browse to and select the icon file you just created.

All set...
