Attribute constructor has a parameter of type '<type>', which is not an integral, floating-point, or Enum type or one of Char, String, Boolean, System.Type or 1-dimensional array of these types

A custom attribute definition includes a constructor that specifies an invalid data type for a parameter. Attributes can take only certain data types as parameters, because only those types can be serialized into the metadata for the assembly.
