@Nitin sir : i have refered that link it explains a lot about my issue... @Apurba : i already done with that but it not helps me  because i need OWIN startup class and after adding Version 1.1.3 i am not able to find Owin. So i searched for further versions of signalr...

Hi Dinesh your Visual studio version 2010 and you are trying to install SignalR 2.1.0 Try installing a different version of signal r with this command (via nuget package console) 'install-package Microsoft.AspNet.SignalR -Version 1.1.3'. Latest version of signalr requires .net4.5 but you dont have that.

Microsoft ASP.NET SingnalR is fairly latest feature. If your organization (or you) want to explore and implement latest features with earlier version older tools that wouldn't be possible isn't it? I am not aware of size of your organization but it is possible to use up-to 5 installations of Microsoft Visual Studio 2015 Community Edition absolutely free if the turn-over of your organization is less than a million dollars. I have already seen the screen shot the error is quite clear. No need of any further explanation. Did you see the link I provided?

Looks complicated please refer tohttp://stackoverflow.com/questions/12390175/targeting-net-framework-4-5-via-visual-studio-2010 Any reason why you are not upgrading Visual Studio Version? Just curious.
