This is the error I get trying to run from IIS7... I can run fine it seems out of VS2008 Cassini.... So I'm not certain what the issue is, I have the 7/16/2009 trunk build of S#arp and MVC.Net 1.0. The piece of code it is failing on is in the global.asax.cs Init() method. I really am pretty frustrated with this issue, because I have only found one other post concerning this, and it was in test cases, where as mine is actually trying to run the website from iis7 and all my tests pass fine.

If anyone has any idea what may be causing this issue, that would be great, thank you.

Probably a threading issue?

Have you tried something like this in your app initialisation:

private static bool haveInit
if (!haveInit)
{
    lock (@lock)
    {
        if (!haveInit))
        {
            NHibernateSession.Init(...);
            haveInit = true;
        }
    }
}

I recently had the same problem. I used S#arp arch but used a normal asp.net website project (integrated in a cms). The whole problem for me was that Global.asax does not trigger on unknown filetypes or virtual urls. I solved it by writing my own HttpModule and loading it separately, this has the side-effect that NHibernate is initiated even though someone is only fetching an image. but for me it wasn´t an issue.

Hopefully that puts you in the right direction...

This sounds like IIS7 is not configured properly for ASP.NET MVC. See if this post on SO helps you in setting up IIS7 with ASP.NET MVC. I'm also using SharpArchitecture and after having IIS7 run in "integrated" mode, solved a bunch of issues.
