从vs2010迁移到vs2012后，Linq包含不起作用

Question

I just migrate my project from vs2010 to vs2012 and when I try to execute this method the statement seems to get no data. The same code works fine on vs2010.

var result2 = (dc.Table1
    .Where(p => p.Descripcion.Contains(descripcion) && p.Estado == 1)
    .GroupJoin(dc.Table2, 
        p => p.Codigo, 
        a => a.Codigo,
        (p, a) => new { p = p, a = a }
    )
    .SelectMany(
        temp => temp.a.DefaultIfEmpty(), 
        (temp, a) => new Listado() 
        { 
            codigo = temp.p.Codigo, 
            descripcion = temp.p.Descripcion, 
            alias = a.Descripcion, 
            id = a.Id 
        })
    )
    .ToList();

Any suggestion to fix the problem is welcome.

Answer 1

I solve it by upgrading to EntityFramework6, it seems that EntityFramework5 still has some bugs. I am using the same method and data but now I'm getting the expected data.

Answer 2

我认为在升级EntityFramework时遇到了类似的问题，结果我改用了.Any（）方法。
