What's new in Visual Studio 2008 vs 2005 or C # 3.0 vs C # 2.0?

Question

I looked through the Hidden Features of C # question and thought I would try one of the functions that I am not familiar with. Unfortunately, I am using Visual Studio 2005, and this feature was introduced later. Is there a good list for new features in C # 3.0 (Visual Studio 2008) and C # 2.0 (Visual Studio 2005)?

Answer 1

This is not an exhaustive list, but these are some of my favorite new C # 3.0 features:

Initializers of a new type. Instead of this:

Person person = new Person();
person.Name = "John Smith";

I can say the following:

Person person = new Person() { Name = "John Smith" };

Similarly, instead of adding individual elements, I can initialize types that implement IEnumerable as follows:

List<string> list = new List<string> { "foo", "bar" };  

- . , :

people.Where(delegate(person) { return person.Age >= 21;);

:

people.Where(person => person.Age >= 21 );

:

public static class StringUtilities
{
    public static string Pluralize(this word)
    {
       ...
    }
}

- :

string word = "person";
word.Pluralize(); // Returns "people"

. . , " ", :

var book = new { Title: "...", Cost: "..." };

One of the unknown but powerful features of Visual Studio 2008 is T4 (Text Template Conversion Tool) . T4 is a code generator built right into Visual Studio 2008.
