Métodos Set (LINQ to Entities)

  • Artículo

La mayoría de los métodos Set de LINQ se admiten en consultas de LINQ to Entities, a excepción de las que usan EqualityComparer. Para obtener más información, vea Operadores de consulta estándar en las consultas de LINQ to Entities. La tabla siguiente enumera los métodos Set admitidos y no admitidos.
