Web Api 2 - FromBody object always null when a variable contains ampersand

I have an endpoint specified that reads the request body using [FromBody], but, the value is always null when one of the fields contains an ampersand (&). The client in question is passing XML to the endpoint.

public IHttpActionResult CreateStage([FromBody] JobStageWrapper stage)

The JobStageWrapper object

public class JobStageWrapper
{
    public JobStage job { get; set; }
}

The Stage object

public class JobStage
    {
        public string jobno { get; set; }
        // Job Stage
        public string jobStage { get; set; }
        // Stage Date
        public DateTime StageDate { get; set; }
        public string Memo { get; set; }
    }

So, for example:

<memo>My name is Adam & I live in England</memo>

Returns null

<memo>My name is Adam and I live in England</memo>

Returns a populated object

Is there a way I can intercept the request body to replace these special characters so that the object is always fully populated?

Thanks!
Adam

The client should make sure that the xml is escaped. Ampersand should be passed as &amp;

This is not a valid xml element

<memo>My name is Adam & I live in England</memo>

but this is

<memo>My name is Adam &amp; I live in England</memo>

See List of XML and HTML character entity references -> Predefined entities in XML section for a list of special characters in XML that need to be escaped.

Or here is the list copied from this previous answer on SO What characters do I need to escape in XML documents?.

"   &quot;
'   &apos;
<   &lt;
>   &gt;
&   &amp;
