WebApi Help Page: don't escape HTML in XML documentation

问题

I am using XML Documentation for my ASP.NET Web API Help Page as shown here. I would like to know if there is a way to include html in the comments such that it will be rendered on the web page, instead of it being removed/ignored/escaped.
Specifically, I am looking for a way to create a newline, but being able to create bulleted lists, etc. would be great!

Ex/ I would like to be able to do something like this:

/// <summary>
/// CRUD operations for SalesDocument<br/>
/// This is a new line
/// </summary>
[RoutePrefix("api/SalesDocument")]
public partial class SalesDocumentController : ApiController

And have it show on the help page like this:

CRUD operations for SalesDocument 
This is a new line.

Instead of this: (in this case, <br/> gets removed somehow - if I try using <p> tags, they are just escaped)

CRUD operations for SalesDocument This is a new line.

*I have already tried the <para> tag as suggested by multiple posts for tooltips, but this does not work on my help page.

Any suggestions are greatly appreciated!

In the installed XmlDocumentationProvider.cs file at Areas\HelpPage, you can look for a method called GetTagValue. Here modify the return value from node.Value.Trim() to node.InnerXml.

private static string GetTagValue(XPathNavigator parentNode, string tagName)
{
    if (parentNode != null)
    {
        XPathNavigator node = parentNode.SelectSingleNode(tagName);
        if (node != null)
        {
            return node.InnerXml; 
        } 
    }

    return null;
}

Now open the installed file Areas\HelpPage\Views\Help\DisplayTemplates\ApiGroup.cshtml and modify the following line from:

<p>@controllerDocumentation</p>

to

<p>@Html.Raw(controllerDocumentation)</p>

@controllerDocumentation does not work for me, but changing the line to@api.Documentation works. i.e. @html.raw(api.Documentation).
