linq-to-entities
Problem returning Entity models: "the entity or complex type ... cannot be constructed in a LINQ to Entities query"
I am trying to return a list of the objects generated by Entity Framework DataBase first but I get this error:
The entit ... ength(100)]
public string nome { get; set; }
public virtual ICollection<TB_LEMBRETES> TB_LEMBRETES { get; set; }
}
Are there any differences between first and Single? [duplicate]
this question already has an answer here :
... two queries equal?
And in terms of performance between the two is the same?
Which of the two expressions is better to use?
Left Join with LINQ

I al ... from m in tmpMapp.DefaultIfEmpty()
select a;
In SQL would be
SELECT a LEFT JOIN b on a.Codigo = b.Codigo
