For a hex literal that’s not prefixed you can quite easily convert it using int.Parse in C#: But as you’ve probably noticed, most hex literals are prefixed with 0x (e.g. “0x142CBD”) which would throw a FormatException if you try to parse it using the above code. In order to parse a 0x prefixed hex literal …
Definition: Domain Driven Design (DDD) is an approach to software design which puts the focus on the problem domain and provides a structure for making design decisions to accelerates software development for complicated domains. The key components in DDD include: Domain: the subject area to which your program is applied Model: abstractions that describe aspects …
Use ReSharper? Notice every time ReSharper sees code like this: it complains, and tells you to get rid of the ex for the reason ‘Exception rethrow possibly intended’? The reason ReSharper is warning you about an ‘exception rethrow’ is that when you rethrow an exception it replaces the stack trace of the original exception with …

Consider the example below, where the …
This is an upcoming web seminar with Scott Gu, organised by the good folks at Linked .Net User Group (http://www.lidnug.org).

Whilst reading through the various posts, I came across an unfamiliar term …
When dealing with concurrency/threading issues in .Net, the normal approach is to use lock() to lock a dedicated sync object like this: This is an efficient, simple and well proven way to get thread-safety in .Net and is probably all you’ll ever need in your project. However, as this approach ensures only one thread can …
In Linq To Objects, there are two ways you can join two sequences together, using either Concat() or Union(), and as I was wondering how the two differs I came across this post: http://weblogs.asp.net/fbouma/archive/2009/03/04/choose-concat-over-union-if-possible.aspx The main thing to take away from this article is: “If you care about the duplicates, Union() is necessary. However, in …
