It is an important concept in C# that is related to how the compiler handles different kinds of variables in memory. Knowing how the compiler handles the various types allows you to avoid unexpected side effects in your code. This article explains what boxing is, how it works and how it can negatively effect your code if you don't pay attention to it.

Interesting Observation of ON Clause on LEFT JOIN

Mon, 16 Mar 2009 21:16:19 GMT

Very simple explanation of : Although the placement of such predicates does not make a difference for INNER joins, they might cause a different result when OUTER joins are involved. This is because the predicates in the ON clause are applied to the table before the join, whereas the WHERE clause is semantically applied to the result of the join.

Unit Testable HttpModule and HttpHandler - Kazi Manzur Rashid's Blog

Thu, 12 Mar 2009 23:31:11 GMT

With the new System.Web.Abstraction namespace we can now easily write unit testable HttpModule and HttpHandler. In this post, I will show you how to write unit testable HttpModule and HttpHandler. Prior the release of System.Web.Abstraction the problem with unit testing of these web infrastructural items is HttpContext, it is sealed, no way to mock it with Rhino or Moq. The only option is to create the wrapper objects of these non-mockable objects but it has a very long tail like HttpRequest, HttpResponse, HttpSessionState, HttpServerUtility etc etc. And this is the exact thing that the System.Web.Abstraction provides, all wrappers around the non-mockable objects of HttpContext. But still, both the HttpModule and HttpHandler depends upon the original HttpContext which I hope will change in ASP.NET 4.0. till then we need to create a super layer for making it Unit Testable.
