I have a SignalR Hub (called SignalRHub) on which I have enabled tracing to diagnose intermittant delivery failures. When I install the hub into IIS 7.5 (Windows 3008 R2) the tracing outputs the following warning

SignalR.ReflectedHubDescriptorProvider Warning: 0 : Some of the classes from assembly "Microsoft.AspNet.SignalR.Owin, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" could Not be loaded when searching for Hubs. [C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\SignalRHub\4ccc0432\cdbbac63\assembly\dl3\8421904d\0082ca11_2b40d001\Microsoft.AspNet.SignalR.Owin.dll]
Original exception type: ReflectionTypeLoadException
Original exception message: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Has anyone seen this before and if so, is it an issue? I believe all the libraries are installed with the hub.

Any help would be most gratefully received.

  • As per exception message: `Retrieve the LoaderExceptions property for more information.` - what are the LoaderExceptions? – Pawel Feb 10 '15 at 21:24
  • Unfortunately I can't seem to find anywhere where I can catch this error, to look at the exception – rideintothesun Apr 29 '15 at 10:21
  • You can turn on Fusion logging which will log failures. See http://stackoverflow.com/questions/255669/how-to-enable-assembly-bind-failure-logging-fusion-in-net – Pawel Apr 29 '15 at 13:00
