Compiler Error Message: BC30560: 'Chart' is ambiguous in the namespace 'dotnetCHARTING'

protected dotnetCHARTING.Chart Chart;
|

Rename the chart or page.

Your VS project references a dotnetCHARTING dll that is not the same as the dotnetCHARTING dll in the project's bin folder. For instance if you have the server version installed and the website dll resides in your bin folder.
SOLUTION 2
Delete the dotnetCHARTING reference and specify the correct dll.
