I have an ASP.NET MVC app which uses NH (2.1) and RSB (compiled from
git). I would like to push database work and message sending into one
transaction. That's why I open a TransactionScope in the
Application_BeginRequest and dispose in the Application_EndRequest.
protected void Application_BeginRequest()
{
HttpContext.Current.Items[TransactionKey] = new
TransactionScope
();
CurrentSessionContext.Bind(factory.OpenSession());
}
protected void Application_EndRequest()
{
if (CurrentSessionContext.HasBind(factory))
CurrentSessionContext.Unbind(factory).Dispose();
var scope = (TransactionScope)HttpContext.Current.Items
[TransactionKey];
if(scope != null)
{
scope.Complete();
scope.Dispose();
}
}
In the controller action I have some stuff like:
public ActionResult Submit(NewSolutionForm model)
{
var submission = new Submission
{
// omitted for clarity
};
session.Save(submission);
bus.Send(new JudgeSubmission {SubmissionId =
submission.Id});
return this.RedirectToAction(x => x.ViewStatus
(submission.Problem.Contest.Id));
}
session is injected by the container.
The problem is I get InvalidOperationException:
The operation is not valid for the current state of the enlistment.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

I was not able to reproduce the bug in a separate application. There
it works just fine.
Any clues why this happens?
Any ideas if I should put the database work and message sending in one
transaction at all? Anybody did that successfully?
