I have deployed a feature (wsp) on our new production server but get the following error:
error CS0234: The type or namespace name 'DirectoryServices' does not exist in the namespace 'System'
The feature had been working fine on the test system. Have I forgotten something? Does deploying directly from VS2010 do something different than deploying by hand?
More Information The feature is a replacement for the smallSearchBox. The error message is written to the log and my search box does not appear. The deployment in test is done via VS2010. In production the WSP is copied and installed by hand.
