I'm pretty new in ASP.NET MVC (about 3 months) and i've the followin issue:

I have a Entity Class called 'Usuario' in a ClassLibrary referenced as 'Core' and, when i create a strongly-typed view and add a html.textboxfor<> like:

<%= Html.TextBoxFor(u => u.Login) %>

it raises the following error:

Error   3   The call is ambiguous between the following methods or properties:
'Microsoft.Web.Mvc.ExpressionInputExtensions.TextBoxFor<Core.Usuario,string>(System.Web.Mvc
.HtmlHelper<Core.Usuario>, 
System.Linq.Expressions.Expression<System.Func<Core.Usuario,string>>)' and 
'System.Web.Mvc.Html.InputExtensions.TextBoxFor<Core.Usuario,string>(System.Web.Mvc.HtmlHel
per<Core.Usuario>,     System.Linq.Expressions.Expression<System.Func<Core.Usuario,string>>)'
