    Hello Frieds..

    I am using .net framework 4.0 and upgraded to 4.5. and install Signal R of Version 2.2.0.

    so its installed successfully. but i m not getting user interface for add owin startup class file.

    so i have added manually owin startup class file. but  getting this error 

    'Owin.IAppBuilder' does not contain a definition for 'MapSignalR' and no extension method 'MapSignalR' accepting a first argument of type 'Owin.IAppBuilder' could be found (are you missing a using directive or an assembly reference?)

    Hi Dhruvik Sathvara,

    According to your description, I suggest you could try to re-install the owin package.

    Update-Package Owin -Reinstall

    If this still couldn't solve your issue, , I suggest you could try to run below command in the package management console.

    Microsoft.AspNet.WebApi.OwinSelfHost

    Hi Dhruvik Sathvara,

    I suggest you could try to create a new asp.net and install the signalr package and test again.
