Namespace could not be found

[LucaNitti]

I tried to create a generalized function to create a csv file from every class omitting the object field (only string, number, boolean date etc etc)

when i run it i get the following error

Line 157: The type or namespace name 'it' could not be found (are you missing a using directive or an assembly reference?)

and in the Stacktrace is

in FileHelpers.Dynamic.ClassBuilder.ClassFromString(String classStr, String className, NetLanguage lang, List`1 additionalReferences)

in FileHelpers.Dynamic.ClassBuilder.CreateRecordClass()

The namespace of my application is something like
it.mycompany.client.project.main.lib.Model.ModelEdmx for autogenerated class

it.mycompany.client.project.main.web.Management.AsyncTask for the class where the function is.

The class has using it.mycompany.client.project.main.lib.Model.ModelEdmx
