Enterprise Library 5 Logging block throws SynchronizationLockException

Inside Global.asax.cs I get: Object synchronization method was called from an unsynchronized block of code

protected void Application_Start()
    {
        InitContainer();

        AreaRegistration.RegisterAllAreas();

        RegisterRoutes(RouteTable.Routes);

        ControllerBuilder.Current.SetControllerFactory(typeof(UnityControllerFactory));
        CheckForAndMinify();
        Logger.Write("test"); //exception
       // if (System.Diagnostics.Debugger.IsAttached)
           // MvcContrib.Routing.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes);
        //RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes);

    }

Environment:

• Asp.net Mvc2
• VS2010
• Windows7 Enterprise 64bit
• Unity framework starts up before this logging code

I'm trying to make sure the logger works on application startup so that the app doesn't startup, look correct and then dies as soon as the first attempt to log something happens.

The logging xml configuration has not changed, it was previously working. The major change was adding Unity, and switching the app from linq to sql. I have not confirmed if this code works in the deployment environment, so it could be that it works in the proper environment for some reason and not locally.

If you run the app outside of Visual Studio, does it crash? What you're seeing is an issue with Unity and something about how it creates singletons. If you set vs to only show unhandled user exceptions then you wont see it any more. I had the same issue just now. It's retarded. I didn't see this in Enterprise Library 4, just in 5.
