Shared declarative html helpers between projects in Asp.Net MVC

Question

Is it possible to put the declarative html helpers in an assembly different than the application web project?

Currently, the only place where I know I can put my declarative html helpers is in the folder 'App_Code' of my application web project.

After a couple of months of development, I now have a lot of these declarative html helpers and the only one solution I have to shared it among all my projects is with a the very bad practice of 'Copy Paste Driven Development'.

Any other ways?

P.S.

Just not to be confused by the definition of what is declarative html helpers, here is a code sample to makes the difference compared to c# extensions that extend the System.Web.Mvc.Html type:

@using Microsoft.Web.Mvc.Html

@helper YesNoRadioButton(System.Web.Mvc.HtmlHelper html, string name, bool value, bool disable = false)
{
   @html.RadioButton(name, true, value, id: name.Replace(".", "_") + "_Yes", disabled: disable) @:Oui 
   @html.RadioButton(name, false, !value, id: name.Replace(".", "_") + "_No", disabled: disable) @:Non   
}

@helper YesNoRadioButton(System.Web.Mvc.HtmlHelper html, string name, bool? value, bool disable = false)
{
   @html.RadioButton(name, true, value.HasValue && value.Value, id: name.Replace(".", "_") + "_Yes", disabled: disable) @:Oui 
   @html.RadioButton(name, false, value.HasValue && !value.Value, id: name.Replace(".", "_") + "_No", disabled: disable) @:Non   
}

Make a class library of those helpers and then share it among projects.It will be better if you put your helpers in a custom created folder Helpers. This is what I do.
