Using HangFire to call action delegate produces exception - hangfire

Question

I'm trying to use HangFire to call an action method on a class. From the code below, the action method works correctly if called outside of HangFire, but throws an exception when using HangFire. I also tried using Invoke() as stated by other similar posts.
Expression body should be of type
'MethodCallExpression'(Parameter'methodCall')'
I'd like to figure out how to have HangFire execute this type of method if possible.
class Program
{
static void Main(string[] args)
{
var a = new ActionTest();
// Calling this method prints out Hello World correctly
a.DoAction();
GlobalConfiguration.Configuration.UseSqlServerStorage(#"Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=Test;Integrated Security=True");
// Call this method from HangFire produces exception: Expression body should be of type 'MethodCallExpression'(Parameter'methodCall')'
BackgroundJob.Enqueue<ActionTest>(a => a.DoAction());
}
}
public class ActionTest
{
public ActionTest()
{
DoAction = WriteHello;
}
public Action DoAction;
public void WriteHello()
{
Console.WriteLine("Hello World");
}
}

Answer 1

I don't see any other way than wrapping the call to DoAction in a genuine method :
public class ActionTest
{
public ActionTest()
{
DoAction = WriteHello;
}
public Action DoAction;
public void InvokeAction()
{
DoAction();
}
public void WriteHello()
{
Console.WriteLine("Hello World");
}
}
then
BackgroundJob.Enqueue<ActionTest>(a => a.InvokeAction());
