DTC escalation on calling ContinueWith

bug?
1

Hi,

With Hangfire Pro 1.4.8 and Hangfire 1.6.8, I’m seeing any calls to ContinueWith within a TransactionScope escalate to a DTC transaction. Presumably this is because of 2 simulataneous connections, as in https://github.com/HangfireIO/Hangfire/issues/442.

You can replicate it with this minimal code:

[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void TestMethod1()
    {
        using (var ts = new TransactionScope(TransactionScopeOption.Required, TransactionScopeAsyncFlowOption.Suppress))
        {
            JobStorage.Current = new SqlServerStorage(@"Data Source=.\sqlexpress;Initial Catalog=blah;Integrated Security=True;Application Name=Background;Connection Timeout=120");
            GlobalConfiguration.Configuration.UseBatches();
            var batchClient = new BatchJobClient();

            var batchId = batchClient.StartNew((client) => client.Schedule(() => Test.Method1(), DateTimeOffset.Now));

            batchClient.ContinueWith(batchId, c => c.Enqueue(() => Test.Method1()));
        }
    }

    public static class Test
    {
        public static void Method1()
        {
            
        }            
    }
}

Any workarounds or fixes would be much appreciated.
