VS2013 Express错误：无法识别名称空间

Question

I have three projects: BLL, DAL and mycv. after to reference DAL inside BLL, BLL inside mycv, I tried to call a funcion installed inside BLL which is existing.

I am using Visual Studio 2013 Express, MVC5, AngularJS (I added as nuget) and JQuery libraries (I added as nuget).

I installed Target Framework as 4.0 version.

When I use using BLL, the namespace is not recognized.

I give you the structure of my solution and you'll see all the references:

DAL code is:

public class DatosPersonales
{
    public Entities.DatosPersonales getDatosPersonales_DAL()
    {   
        return new Entities.DatosPersonales();
    }
}

BLL code is:

public class DatosPersonales
{
    public Entities.DatosPersonales getDatosPersonales()
    {
        return DAL.DatosPersonales();
    }
}

Finally, in mycv project I call BLL class of DatosPersonales:

public ActionResult Index()
{
    var clase = new DatosPersonales();                
    return View();
}

With that error I can not compile succesfully.

If you need something more to add let me know and I will give you more information.

What is wrong?

Answer 1

Have you checked that your DAL layer i building successfully. Try cleaning the layers and build them one by one. First DAL, then BLL and finally the main layer.

Sometimes if your most inner layer (or DAL in your case) doesn't compiles successfully, it affects the other layers as well.
