Hi voolster,

Welcome to the ASP.NET forum

C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler.exe Error ASPPARSE: Unknown server tag 'asp:CHART'

About this issue, I think first you could confirm that you set the code below in your web.config.

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

Or you can register the controls on the page you are using them.

Further information please refer to the link below.
