SecurityRulesAttribute Exception

  1. working on moving a well functioning app from .net 3.5 to .net 4

    I am getting the following exception; The type or namespace name 'SecurityRulesAttribute' does not exist in the namespace 'System.Security' (are you missing an assembly reference?)

    that is somehow related to using XslCompiledTransform.

    Has anyone seen an error like this?

    This app works fine on Winhost server under .net 3.5 and works fine on local server under .net 4
