As great as LINQ is and how it has transformed the way we interact with data in .Net to the point many of us wonder how we had managed without it all this time! There are however, some pitfalls one can fall into, especially with the concept of delayed execution which is easily the most …
This one took me by surprise a little but there’s something about the Enumerable.Except method which you ought to know about. At first you might have assumed (as I did) that given an array as the base set and calling the Except extension method with a second array will return all the items in the …
You know how Visual Studio neatly collates all the relevant files (the XAML and the code behind file in this case) for you whenever you create a new user control or page in WPF: needless to say, in any sizable UI project this makes life hell of a lot easier navigating through the solution! However, …
When you have a generic interface such as: It’s easy to check whether a given instance implements the IInitializable interface with a specific T: But what if you want to find out if a type implements the IInitializable interface of an arbitrary T? You won’t be able to simply get away with this: Instead, you …

Another good question on StackOverflow, and even better answer from Steven (miles better than what I managed!), the question was around how to implement an extension method to check whether a certain method has a particular attribute applied to it, mainly for the purpose of unit testing. In his answer, Steven provided a couple of …
Came across an interesting question on StackOverflow on how one might be able to throttle the number of requests across multiple servers running the same WCF service. So for instance, if you have 3 servers sitting behind a load balancer and for one reason or another you can only allow 5 requests to be made …
Stumbled across this question on StackOverflow the other day, definitely one for the interview! The question goes: How do you convert a string such as “01110100011001010111001101110100” to a byte array then used File.WriteAllBytes such that the exact binary string is the binary of the file. In this case it would be the the text “test”. …

One of the less known aspect of the DataContractSerializer is its dependency on the order in which fields are serialized and deserialized. As this article points out, the basic rules for ordering include: If a data contract type is a part of an inheritance hierarchy, data members of its base types are always first in …

Another gem I found on StackOverflow today (I’ve been spending a lot of time there these last couple of days..), this time in the form of a question on how to append or prepend a single value to an IEnumerable<T>. Greg provided an elegant solution to this particular problem, and here’s his answer: Which you …

Before you get your hopes up, sorry, there’s no built-in support to allow you to restrict the usage of your attribute to a type easily. That’s not to say that it’s impossible though! If you’re reading this, I assume that you’ve tried to write a custom attribute yourself and realised that the options available in …
