COM is a platform-independent, distributed, object-oriented system for creating binary software components that can interact. COM is the foundation technology for Microsoft's OLE (compound documents) and ActiveX (Internet-enabled components) technologies.

Step 1: Create Class Library project. Add Interface and call in your class.

[Guid("321A78B5-53F6-499A-9333-1A18A1A87F1B")]
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
[ComVisible(true)]
public interface IAmazonService
{
}
[Guid("29C0007F-ED96-4141-986C-A50DA1AC3CAD")]
[ClassInterface(ClassInterfaceType.None)]
[ComVisible(true)]
public class AmazonOrderService : IAmazonService
{
}

You must be defining all the property and Methods you need to create are public.

[Guid("321A78B5-53F6-499A-9333-1A18A1A87F1B")]
    [InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
