Using windows MessageBox in ASP.NET

I have seen in the forums, lot of people are asking for using Windows MessageBox in ASP.NET. It's pretty simple. Just you need to Add System.Windows.Forms namespace to references. Follow these steps:

1) Right Click on References in your solution explorer
2) Click on Add References. Add References window will be open
3) Under .NET tab select System.Windows.Forms, Click Ok. Now it added to your reference library
4) Import the namespace System.Windows.Forms in your page
C#: using System.Windows.Forms;
VB.NET: Import System.Windows.Forms
5) Now you can use MessageBox.Show();
