When sending the following json to a MS Teams Webhook I can change the color bar above the message with the themeColor Option:

{ "$schema": "http://adaptivecards.io/schemas/adaptive-card.json", "type": "MessageCard", "themeColor": "ff0000", "version": "1.2", "title": "Alarm!", "text": "Test Message" }

How is this possible with the .NET AdaptiveCards SDK that ist available via nuget?
