I have following project:

MyForm unit(just empty form):

unit uMyForm;

interface

uses
System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs;

type
TMyForm = class(TForm)
end;

implementation

{$R *.fmx}

end.

App Unit:

unit App;

interface

uses
uMyForm,
Spring.Container;

type
TApp = class
private
_myForm: TMyForm;
public
[Inject]
constructor Create(myForm: TMyForm);
end;

implementation

uses
System.SysUtils;

{ TApp }

constructor TApp.Create(myForm: TMyForm);
begin
_myForm := myForm;
end;

end.

And build code:

procedure BuildProject;
begin
GlobalContainer.RegisterType<TApp>;
GlobalContainer.RegisterType<TMyForm>;
GlobalContainer.Build;

_app := GlobalContainer.Resolve<TApp>;
end;

Run BuildProject() causes Error: “Cannot resolve type: TMyForm”. I was testing same configuration on VCL platform and there everything is ok. Do you have any idea what is wrong here?

Edit1: I had to change problem description because I was wrong thinking that the problem occurs on both(VCL and FMX) platforms. @RudyVelthuis ‘s comment showed me that problem is only on FMX platform.
