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>

I follow your suggestions but error still present in my server.
Could not load file or assembly 'System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
Please help me..
So am I - still getting the same error, and I've done everything. please help.
Are you guys sure you have .NET 4.0 installed?
Thanks for the post!
I solved my issue the same way last night, so today was searching for 'why' it worked and ran across your page. My hosting provider has IIS 7.5 and the 4.5 .NET Framework and I'm using the 4.0 .NET Framework on my local system.
I also found the System.Web.DataVisualization and System.Web.DataVisualization>Design dlls are not needed in the /bin directory.
Is the only section you removed? It was for me. I kept the , , and changes in the web.config file. What did you do with these other sections?
Sorry. I forgot that the section tags are HTML codes and get stripped. Here's the last paragraph corrected:
Is 'httpHandlers' the only section you removed? It was for me. I kept the 'pages', 'assemblies', 'handlers' and 'appSettings' changes in the web.config file. What did you do with these other sections?
thanks for your post. where is the web.config settings for the C:\TempImageFiles
