With The Release of Visual Studio 2005, The C # Language Has Been Updated to Version 2.0.
Generics (C #)
Generic types are added to the language to enable programmers to achieve a high level of code reuse and enhanced performance for collection classes. Generic types can differ only by arity. Parameters can also be forced to be specific types. See
Generic Type Parameters (C #)
For more information.
Iterators (C #)
Iterators Make It Easier to Dictate How A
Foreach Loop Will Iterage Over a Collection's Contents.
Partial Class Definitions (C #)
Partial Type Definitions Allow A Single Type, Such As a Class, To BE Split Into Multiple Files. The Visual Studio Designer Uses this feature to sedate it. generated code from user code.
Nullable Types (C #)
NULLABLE TYES ALOW A Variable to Contain A Value That Undefined. Nullable Types Areful WHEN Working with Databases and Other Data Structures That May Contain Elements That Contain No Specific Values.

:: Operator
The namespace alias qualifier

How to: Use The Global Namespace Qualifier (C #)
Alias allows access the root namespace That May be hidden by an entity in your code.

Set Accessors on Properties.

The Method Passed to a Delegate May Now Have Greater Flexibility In Its Return Type and parameters.
Fixed Size Buffers (C)
IN AN UNSAFE CODE BLOCK, It's now Possible To Declare Fixed-Size Structures with Embedded Arrays.
Friend assembly (C #)
Assemblies CAN Provide Access To Non-Public Types To other assembly.
#pragma Warning
The #pragma Warning Directive May Be used to disable and enable Certain Compiler Warnings.
