Hosting a SignalR application in Classic Mode on IIS

Question

I am currently working on signalr in asp.net 4.0

 

My entire scenario working fine on VS2010 but when I host it on IIS in classic mode then it showing "Internal server error 500"   .Strange is that when mode is integrated then it working fine. But problem is that my entire project is in classic mode so i want my signalr code also work in classic mode .

 

If any one have solution then please help me.

 

Thanks in advance.
