I build the above code and i get the following error.

C:\\Labs\\CallBusinessRules\\Class1.cs(58): The name ‘xmlReader’ does not exist in the class or namespace ‘CallBusinessRules.CallBusinessRules’
C:\\Labs\\CallBusinessRules\\Class1.cs(67): The type or namespace name ‘xmlReader’ could not be found (are you missing a using directive or an assembly reference?)

Any help greatly appreciated!!!!!!!!!!!
