Edited Unassigned: @helper - wrong class name [171]

I have a razor helper in App_Code/MyHelpers.cshtml

The generated class name in obj/CodeGen is "public class _App_Code_MyHelpers_cshtml"

And of course all my views throw compile errors when referencing "MyHelpers.Something"

Adding @* GeneratePrettyNames : true *@ does not fix the issue since the namespace is invisible in view-code.
