MS Chart Visual Studio 2008 Add-On - Error executing child

I installed MS Chart Add-On for Visual Studio 2008, compiled the project and hit the "Play" button and received a yellow error screen as the below.

To fix this issue, what you have to do is to simply add an additional "verb" to the "httpHandlers" section within the "system.web" section of the ROOT web.config file.

See below for an example

<add verb="GET,HEAD,POST" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />

I found this fix at handy Stack-Overflow. Click here
