Run a.dyn from a Revit add-in?

Okay I have it running.

Don’t use a transaction in the Plugin code, let dynamo handle the transaction independently.
I had to reference a lot of .dlls (see the image below) I may have went overboard.
You can only have one version of dynamo installed (2.x).

namespace DynamoTest
{
    [Transaction(TransactionMode.Manual)]
    [Regeneration(RegenerationOption.Manual)]
    public class RunDynamo : IExternalCommand
    {
        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
        {
            //Get application and documnet objects and start transaction
            UIApplication uiapp = commandData.Application;
            Document doc = uiapp.ActiveUIDocument.Document;           

            string Journal_Dynamo_Path = @"C:\Path To .Dyn\Test.dyn";
            DynamoRevit dynamoRevit = new DynamoRevit();

            DynamoRevitCommandData dynamoRevitCommandData = new DynamoRevitCommandData();
            dynamoRevitCommandData.Application = commandData.Application;
            IDictionary<string, string> journalData = new Dictionary<string, string>
            {
                { Dynamo.Applications.JournalKeys.ShowUiKey, false.ToString() }, // don't show DynamoUI at runtime
                { Dynamo.Applications.JournalKeys.AutomationModeKey, true.ToString() }, //run journal automatically
                { Dynamo.Applications.JournalKeys.DynPathKey, Journal_Dynamo_Path }, //run node at this file path
                { Dynamo.Applications.JournalKeys.DynPathExecuteKey, true.ToString() }, // The journal file can specify if the Dynamo workspace opened from DynPathKey will be executed or not. If we are in automation mode the workspace will be executed regardless of this key.
                { Dynamo.Applications.JournalKeys.ForceManualRunKey, false.ToString() }, // don't run in manual mode
                { Dynamo.Applications.JournalKeys.ModelShutDownKey, true.ToString() },
                { Dynamo.Applications.JournalKeys.ModelNodesInfo, false.ToString() }

            };

            dynamoRevitCommandData.JournalData = journalData;           
            Result externalCommandResult = dynamoRevit.ExecuteCommand(dynamoRevitCommandData);
            return externalCommandResult;

        }
    }
}
