The type or namespace name 'Windows' does not exist in the namespace 'System'

asp.net-mvc-3, c#

Solution

You are not missing any DLL , It seems like you are using the wrong type of project.

Problem

I am trying to code for pop up message box for displaying message for successful record insertion in C#.net Error : The type or namespace name 'Windows' does not exist in the namespace 'System' (are you missing an assembly reference?) Code : ``` global::System.Windows.Forms.MessageBox.Show("Test"); ```
