Custom html helpers in MVC 4

Question

I created the helper class

namespace SEM.API.Helpers
{
    public static class Navigation
    {
        public static string BuildSomething(this HtmlHelper h         


        

Answer 1

and added namespace to webconfig <add namespace="SEM.API.Helpers" />

Make sure you did this in ~/Views/web.config and not in ~/web.config.

Another thing to try is to add the @using directive to your view:

@using SEM.API.Helpers
@Html.BuildSomething()

Answer 2

In addition, you should add to the ~/Areas/[Area name]Views/web.config the same string if Areas used.
