The other day I had an interesting observation on the optional parameters in C# 4, whereby if you specify a parameter as optional on an interface you don’t actually have to make that parameter optional on any implementing class: 1: public interface MyInterface 2: { 3: void TestMethod(bool flag=false); 4: } 5: 6: public class …

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 …
