POCO in ADO.NET Entity Framework 4.0 has been discussed in many places. Here I am not going to talk about it. However, I created a small sample to demonstrate the capability of POCO in much more cleaner “code-only” approach. <<Apology for this blog post issue>>. There were some images, due to which it was not… Read more
In .NET Framework 4.0 Stopwatch.Restart() is new addition. Stopwatch sw = new Stopwatch(); sw.Start(); //Do something //…. //ERROR!!! //Then Restart the Stopwatch sw.Restart(); Namoskar!!!… Read more
In .NET Framework 4.0 we have a new class called SortedSet<T>. This helps us to sort the elements without explicitly we implementing any sort method. var sSet = new SortedSet<int> { 2, 4, 6, 8, 9, 1, 3, 5, 7 }; //Getting directly the sorted output foreach (int iVal in sSet) { Console.WriteLine(iVal);… Read more
The question often arises what is so special in C# 4.0 about COM Interop. To me it is a lot. I will try to explain why.. Assume you are trying to get the list of proccess running locally in your machine and creating them using Excel chart and copying that chart to Word. … Read more

Here I am going to talk about the feature called Covariance and Contravariance. To show you the example I will use delegate. Now what is it? This would be a big question and with no hesitance I must say that you should visit Eric’s blog. There are some articles which will help you understand. To… Read more
While browsing the features I found an interesting extension method called “Zip”. How it works, let’s check it. List<string> names = new List<string> {“Debajyoti”, “Sumitra”, “Wriju” , “Writam”, “Tupur” }; List<int> ages = new List<int>{ 67, 58, 30, 24, 26 }; var zipped = names.Zip(ages, (name, age) => name + ” is “… Read more
For methods having numerous arguments we tend to get confused. And this is also pain for others while reviewing the code. C# 4.0 gives us an opportunity to pass parameters with name. How it works, let’s check it. Suppose you have a method like below, public static class TestClass { public static void ParamMethod(string… Read more
Days of creating multiple overloads to avoid parameters are gone. You no more have to create many methods and pass the default one there. C# 4.0 brings to us the concept of “optional” parameters. How it works, let’s check it. Suppose you have a method like below, public static class TestClass { public static… Read more
“Working with dynamic objects statically” – Anders Hejlsberg When you work with C# 4.0 you get to work with many unmanaged world “dynamically”. What does that mean to you? It means you do not do things “statically” as you used to do in C# or in VB.NET. There are many benefits in static programming like… Read more
I am super excited to see Anders demonstrating C# 4.0 for first time in public. I am a real fan of him and downloaded the public bit to tryout. Here is my first Dynamic C# 4.0 program. There is nothing much to be excited from my Program but I am very much after hitting… Read more
