There are two ways to add Windows Media Player to a WinForms project. However, the second method didn’t work for me:

1. Using the Toolbox:

   • Right-click the Toolbox in Visual Studio and select Choose Items.
   • In the COM tab, locate and add the Windows Media Player component.
   • Drag the component onto the WinForm. This will automatically add the required references to the project.

2. Manually Adding a Reference (did not work in my case):

   • Right-click the References folder in the project tree and select Add Reference.
   • Go to the COM tab, find and select Windows Media Player, and add it to the project.
