Why not to have a static const in c#

This is just a thought, that I was thinking why can't we have a constant with static in C#, and the answer is 'NO'; That we cannot have a static constant; e.g: I created a class as below: public class Constants1 { public const string Const1 = "Hello"; public const string Const2 = "World"; public static string Static1 = "Hello Static"; } When we compile the program into IL, the C# compiler does a magic in IL, that the constants converts into static literals, of course it has to, that's why we are able to access the constants as Constants1.Const1

pjax with MVC, and form post like pjax

Last weekend I was working on a interesting project, and came across an interesting JavaScript library called pjax. More information on pjax: https://github.com/defunkt/jquery-pjax/ http://pjax.heroku.com/ pjax loads HTML from your server into the current page without a full reload. It's ajax with real permalinks, page titles, and a working back button that fully degrades, It just enhances the browsing experience. I just loved the way we could use it with MVC; Below code sample explains how we could use the same with MVC. Clientside code would look as below: Since the Form post is not handled with pjax, we can do a work around as below. Updated _ViewStart.cshtml as below: @{ if (Request.Headers["X-PJAX"] != null || Request.Headers["AJAX-FORM"]!=null) { Layout = "~/Views/Shared/_PjaxLayout.cshtml"; } else { Layout = "~/Views/Shared/_Layout.cshtml"; } } _PjaxLayout.cshtml ...
