E2532 Couldn’t infer generic type argument from different argument types for method ‘%s’

Reason for the Error & Solution

This occurs when a generic method cannot infer the type of its parameters based on their values.

program E2532;

{$APPTYPE CONSOLE}

uses
  SysUtils;

type
  TMyGenClass = class
    class procedure X<T>(A: T; B: T);  overload;
  end;

{ TSmoke }

class procedure TMyGenClass.X<T>(A: T; B: T);
begin
//
end;


begin
  TMyGenClass.X(1, '8'); //E2532 Fix: if the type constraint is the same for both, use the same type of parameters
end.
