Where do I find reference dll for System.Web.UI.DataVisualization.Charting?

Question

We are upgrading a VS solution from SP2010 to SP2013. We are using VS2010 and Windows Server 2012 OS.

Can you tell me where is the DLL for System.Web.UI.DataVisualization.Charting; located? The error I get is:-

Error 7592 The type or namespace name 'DataVisualization' does not exist in the namespace 'System.Web.UI' (are you missing an assembly reference?) C:\dev\Project\MyPartsControl.ascx.cs

I was browsing for help and got this link which mentions to look under: c:\program files (x86)\Microsoft Chart Controls\Assemblies. There is no c:\program files (x86)\Microsoft Chart Controls directory in my computer.

Answer 1

It is present here

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5

When adding dll references click on Framework and scroll down, you should be able to see this:

Do you reference it in your web.config

•under the controls tag (path: "< system.web>") :

< add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

•under "< httphandlers>") :

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