Aqu\u00ed tienes un ejemplo de un sistema de login y autenticaci\u00f3n simple en C# utilizando ASP.NET Core. En este ejemplo, utilizaremos Entity Framework Core para acceder a la base de datos y ASP.NET Identity para manejar la autenticaci\u00f3n y la gesti\u00f3n de usuarios. Aseg\u00farate de haber configurado Entity Framework Core y haber creado una base de datos antes de comenzar.<\/p>\n\n\n\n
