    Hi, after installation perform these procedures related to the error does not occur, but when I compile the line of Telerik.charting in WebConfig, this returning, causing the error described. What can I do?

    Error: 1 The type 'Telerik.Charting.<SomeType> exists in both 'c:\WINDOWS\assembly\GAC_MSIL\Telerik.Charting\...\Telerik.Charting.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\...\RadChart.Net2.DLL'

    I try this:
    1) If you are migrating your projects to use RadControls "Prometheus" you may initially want to remove the reference to the Telerik.Charting.dll from your Web.config file. In this case you will be using the old ASP.NET Chart and will not need the Telerik.Charting.dll that comes with the Prometheus suite. The Telerik.Charting.dll is NOT required for the operation of the "Prometheus" controls other than Chart.

    and that
    2) If you are already using RadChart "Prometheus" then you will need to remove reference to RadChart.Net2.dll and continue using Telerik.Charting.dll

    Hello Silderado,

    The error suggests that you still have a reference to RadChart.Net2.dll in your project or you need to clear the ASP.NET cache. To clear the cache, please delete the content of this folder:

    c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\
