I’ve decided to add the new ASP.NET 4.0 Chart Control to one of my web apps. Everything worked fine during the testing on my local machine, but once I published it to remote IIS 7.0 server I’ve got the following error:

HTTP Error 500.23 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

Turns out that it occurs because ASP.NET modules and handlers should be specified in the IIS <handlers> and <modules> configuration sections in Integrated mode.

So the simple solution that worked for me was just to remove the following entry from web.config <system.web> section:

<httpHandlers>
<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,
    System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35"
    validate="false" />
</httpHandlers>

Also make sure that <system.webServer> section has the following:

<handlers>
	<remove name="ChartImageHandler" />
	<add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST"
        path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,
        System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</handlers>
