//1. Set the path of the XAML workflow to invoke.

string workflowFilePath = @"..\..\..\WorkflowLib\Training\TestWorkflow.xaml";

//2. Optionally add any parameters required by the workflow

//3. Call ExecWorkflow or ExecWorkflowInDES if connected to a DES database.

//var response = WorkflowUtil.ExecWorkflowInDES(workflowFilePath, exchangeParams);

WorkflowUtil.ExecWorkflow(workflowFilePath, exchangeParams);
