This is an upcoming web seminar with Scott Gu, organised by the good folks at Linked .Net User Group (http://www.lidnug.org). I attended one of their previous presentations with Joe Albahari on the new features in C# 4.0 (the recorded presentation can be viewed here) and thoroughly enjoyed that! A FREE web seminar with someone as …
I spent a bit of time on Ayende’s blog today, finally catching up with a series of performance-related blog posts he made whilst working on the .Net profiler (the man’s a living legend, the quality AND quantity of his posts is without equal!) 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 …
Some time ago I read about (might be on DotNetRocks) a little gem coming out of Microsoft’s research lab called Pex, which is a framework for doing automated White Box Testing in .Net. It’s still in its early days (despite having been around for more than 2 years now) but packs a bag of potential …
I came across this blog post the other day which introduced to me a cool addition to the DataContract serializer – the ability to generate XML by reference rather than by value: http://www.zamd.net/2008/05/20/DataContractSerializerAndIsReferenceProperty.aspx Not much for me to add to it really, just read the blog to see how it works.
Using entity classes in your application and WCF is complaining about the circular references between your classes? Well, I had the exact same problem not long ago, and I found this post on James Kovac’s blog about circular references and how to get around them: http://www.jameskovacs.com/blog/GoingAroundInCirclesWithWCF.aspx The key things to note from this post is …
The Dispose pattern is something we’ve all seen before, and it’s so tried and tested most of us (especially myself!) have been more than happy to apply without question. Whilst reading various blogs/articles I came across some differing opinion about this well known pattern and started to question what I had taken for granted myself. …
Over the last couple of years, there have been many discussions/debates on DataSet vs Collections, and there was a very good article in MSDN magazine on just that: http://msdn.microsoft.com/en-gb/magazine/cc163751.aspx#S7 To add to the Dark Sides of DataSet, there is a little known feature/bug/annoyance in the DataTable.Select() method – every time you call the Select() method …
I did some performance optimization work a little while back, and one of the changes which yielded a significant result was when I migrated some server side components (which are CPU intensive and performs a large number of loops) from using ADO.NET DataSets to using POCOs (plain old CLR object). The looping was then done …
