Comentarios

Cuando el tiempo de ejecución carga un ensamblado, no establece la KeyPair propiedad . El captador de la propiedad solo es útil si el usuario establece la propiedad antes de usar el AssemblyName objeto para crear un ensamblado dinámico y, posteriormente, desea recuperar el par de claves.
