E2020: Object or class type required

This error message is given when the syntax 'Typename.Methodname' is used, but the typename does not refer to an object or class type.

program Produce;
type
  TInteger = class
    Value: Integer;
  end;
var
  V: TInteger;
begin
  V := Integer.Create;
end.

Type Integer does not have a Create method, but TInteger does.

program Solve;
type
  TInteger = class
    Value: Integer;
  end;
var
  V: TInteger;
begin
  V := TInteger.Create;
end.

Make sure the identifier really refers to an object or class type - maybe it is misspelled or it is hidden by an identifier from another unit.
