C# 4.0

When C# first appeared, many saw it as a direct competitor to the Java language’s dominance in enterprise application development. This was often attributed to the syntactical similarities that the two languages shared. Since its introduction, however, C# has continued to move forward with the adoption of language features such as lambda expressions, extension methods, object initializers and automatic property setters and getters, all of which are available in the 3.5 release of the language. With the 4.0 release of C#, we will see the introduction of a dynamic keyword and named and optional parameters, which will continue to bring C# more in line with languages such as Ruby and well ahead of the Java language.
