Configure ASP.net 4.5 for Charting - asp.net

Question

I need a way to configure ASP.net 4.5 for Charting.
Error in line:
<assemblies>
<add assembly="System.Web.DataVisualization, Version=4.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</assemblies>
Error code:

Charting comes built in to ASP.NET 4+. Unfortunately, there are still some glitches with adding it to projects. The easiest way I found to add charts was to actually drag the item out of the Toolbox into an aspx page. It did some background operations to the Web.config file and the page I added the control to.
Here's what it added to the Web.config file:
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.5">
<assemblies>
<add assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</assemblies>
</compilation>
</system.web>
</configuration>
Here's what it added to the aspx file to which I added the control:
<%# Register Assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Namespace="System.Web.UI.DataVisualization.Charting" TagPrefix="asp" %>
Unfortunately, it still did not work as is. I had to make a couple more adjustments to the Web.config file:
<configuration>
<appSettings>
<add key="ChartImageHandler" value="storage=memory;timeout=20;" />
</appSettings>
<system.webServer>
<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>
</system.webServer>
</configuration>
