I have an asp.net application assembly which I am trying to access from within the report designer. I have added the reference and copied the .dll and all the other stuff I think is supposed to happen, but now I am getting an error when the assembly is trying to access the keys it would normally find in the web.config file

"The value expression for the field ‘Value’ contains an error: The key 'ConnString' does not exist in the appSettings configuration section"

Where is reporting services expecting the appsetting tag to be?? I have copied the web.config file to the same location as the .dll, I have also tried adding the key to the RSReportDesigner.config file and the RSReportServer.config file.

Any help is greatly appreciated.

Thanks,

Don
