How to store razor helpers globally

ASP.NET MVC Razor helpers are a great way of reducing duplicated code by containing code snippets in a View which can then be called multiple times.

<div>
    @DisplayGreeting("Curtis")
</div>

@helper DisplayGreeting(string name)
{
    <span>Hello @name</span>
}

However what if you wish to call this same helper on another View?

In which case the helper can be stored in a seperate View in the “App_Code” folder.

For example create a new View in the “App_Code” folder called “MyHelpers.cshtml”:

Move the helper code into this file:

Then the helper can be called from the previous view by using MyHelpers.DisplayGreeting:

<div>
    @MyHelpers.DisplayGreeting("Curtis")
</div>

This way any View within the same ASP.NET MVC Application can then make use of this helper.
