Can't figure out how to use the @mention via these classes.

[ClintBritt]

I can create my own Json to send via a WebHook that supports @mention, Works OK, but I can not seem to be able to form the same Json using AdaptiveCards class:

The following works perfect for me, just need to know haow to use the SDK to do this same thing!!!

{
"type": "message",
"attachments": [
{
"contentType": "application/vnd.microsoft.card.adaptive",
"content": {
"type": "AdaptiveCard",
"body": [
{
"type": "TextBlock",
"size": "Large",
"weight": "Bolder",
"text": "BUILD NOTIFICATION",
"Color": "Good"
},
{
"type": "TextBlock",
"size": "Medium",
"weight": "Bolder",
"Color": "Accent",
"text": "A build was kicked off at "
},
{
"type": "TextBlock",
"text": "This is a build notification for: name1, name2"
}
],
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"version": "1.0",
"msteams": {
"entities": [
{
"type": "mention",
"text": "name1",
"mentioned": {
"id": "name1@somecompany.com",
"name": "name1"
}
},
{
"type": "mention",
"text": "name2",
"mentioned": {
"id": "name2@somecompany.com",
"name": "name2"
}
}

            ]
        }
    }
}]

}
