Errors in Visual Studio

Question

Visual Usage Studio Express 2013 for Web.

I don’t know much about him, I’ve been learning in practice.

It indicates many errors as if my class had not determined attribute.

I noticed that this happens mainly when you change a class by adding some attribute. The new attribute seems not to be interpreted.

And you see, if I have a Build, there is no error, the project is compiled in its entirety. I can run and nothing wrong will happen.

Minutes later, in the Error List errors start to appear indicating that those new attributes are not part of the class such. And on the screen, in the View where that attribute was used, or in the Controller, it appears underlined indicating a possible error.

Now an example: This is my class:

public class ContaAReceber 
{
    [Key]
    public int ID { get; set; }

    [Required]
    public int TipoReceitaID { get; set; }
    public virtual TipoReceita  TipoReceita { get; set; }

    [Required]
    public int CentroCustoID { get; set; }
    public virtual CentroCusto  CentroCusto { get; set; }

    public int? HonorarioID { get; set; }        
}

In the class it can be seen that there is an Honorarioid attribute.

Now look at the image of my VC showing as if there was no attribute:

it is as if VS had saved and compiled the class in its initial form and not renewed it.

Can someone tell me what’s going on and how to make it stop.

Thanks in advance.
