Accepting invalid SSL certificates programmatically (C#)
This might initially sound like a very bad idea, because it undermines one of the fundamental reasons for using SSL in the first place. But it’s suprising how often I come across situations where this comes in very handy, especially during development and testing when v...
Sharepoint 2010 – access site usage statistics
OK, so you made the assumption that Microsofts Sharepoint team would have provided a simple way to access something as common (and not to mention extremely useful!) as site usage statistics. Which pages and resources are accessed at what time for how long how often the ...
Custom mapping? No, I use Automapper!
In the previous posts i wrote about web applications communicating with the backend through a JSON REST API. I mentioned that I like to design specific REST methods for the given Views. That means we have to do some mapping from the objects given by the backend to the v...
CORS = XmlHttpRequest to other servers – without JSONP
As Webstep guru Thor Halvor explained in the this excellent blogpost – there are security restrictions to prevent/limit cross domain access of XMLHttpRequest’s – the cornerstone of AJAX. Flash and silverlight has the same restrictions – and solves this by using c...

TransactionScope – atomic transactions in C#
From the world of databases we are familier with the term "atomic operation" : If not all operations succeed, don’t do any of them. An example is a banking system, where you move funds between accounts. If you deduct an amount from account #1 in operation 1, you...
ASP.NET MVC with Cleaner Data Annotations
While using data annotations with localization in your MVC model, you may end up with some untidy looking code like in this example, where all we do is adding display information and validation: 1: public class Character { 2: [Display(Name="Character_FirstNam...
LINQ – How to build a dynamic WHERE clause (C#)
LINQ is brilliant, and if you know how (and not to mention where, when and on what) to use it it will really improve the readability of your code and save you a hell of a lot of time. One thing that is missing though, is a direct implementation of the “in” statement, kn...
