MohammadSabbir: you have to have using with extension namespace in your controller.
For example, if your FlashMessageExtensions.cs is in namespace Something.Extensions, you have to add using Something.Extensions; in your controller.
The "jQuery.flashMessage.js" javascript no longer works properly if you use latest version (v3.1.1) of jquery! Hopefully someone who knows javascript will post an update :) By the way, great utility I found it very helpful.
I'm using one of the fixes done to the original code (by thomkaufmann) and wanted to know the license terms if the code snippet can be used in other projects.
Thanks

whould you please add references.
'System.Web.Mvc.RedirectToRouteResult' does not contain a definition for 'Success' and no extension method 'Success' accepting a first argument of type 'System.Web.Mvc.RedirectToRouteResult' could be found (are you missing a using directive or an assembly reference?
i can't remove this problem
