4. Too Many New Features… Will focus on specific new features
Pertinent to most developers

5. Two Faces of Visual Studio 2010
Visual Studio as an Editor
Visual Studio as a Platform

6. As An Editor… An improved focus on… Shell rewritten using WPF
Writing code
Understanding code
Navigating code
Publishing code
Shell rewritten using WPF
Adds many new capabilities

7. As a Platform Visual Studio 2010 supports gallery of extensions
Thriving third-party market

8. VB & C# 2010 Language Feature VB C# Auto-implemented Properties
Collection Initializers
Array Literals
Statement Lambdas
Implicit Line Continuation
N/A
Named/Optional Parameters
Latebinding support (dynamic)
Omit ref on COM calls
Indexed Properties
Interop with Dynamic Languages
Co/contravariance
PIA deployment not needed
New in VS 2010
Already exists in VS 2008

9. VB & C# 2010 IDE Feature VB C# Generate From Usage: Generate Method
Type colorization
Background Squiggles: Top Level Analysis
IntelliSense: Builder UI
IntelliSense: Prefix Filtering Completion List
Generate From Usage: Generate Type, Constructor, Property, Field
IntelliSense: Consume First Mode
IntelliSense: Substring & Camel-Case Match
Navigate To
Highlight References
Call Hierarchy
New in VS 2010
Already exists in VS 2008

10. General Improvements Start page
Rewritten using XAML—easy to customize
Recent Projects list: right-click, pin
New projects: Multi-targeting
New support for Silverlight, MFC, F#, Azure
Extended support for Office 2010, SharePoint
Extension manager
Gallery for Visual Studio extensions

11. UI Improvements Zoom Docking Windows Generate from Usage
Highlighting References
Navigate To/Quick Search
IntelliSense Consume-First Mode
Box Selection
Search in Add New Item dialog box

12. Zoom Ctrl+Mouse Wheel New features that enhance the size of your code
Useful for presentations, pair programming

13. Docking Windows New docking visuals Windows can be docked anywhere
Better use with multiple monitors

14. Generate from Usage
Automatically creates “stub” code from code you have typed
Enables you to use classes and members before you define them

15. Highlighting References
Automatic highlighting of symbols
Works with declarations, references, and many other symbols
Makes it easy to find all uses of a symbol

16. Navigate To/Quick Search
Ctrl+,
Provides search-as-you-type support for files, types, and members
Enables quick searching
Provides “fuzzy” search
Ctrl+- goes back

17. Box Selection
In VS 2008, could press ALT key to select rectangular region
Now, additional features:
Text insertion: Type into a box selection to insert text on every line
Paste contents from one box selection to another
Zero-width boxes
Make a vertical selection zero-width to create multi-line insertion point for new or copied text

18. IntelliSense Consume-First Mode
IntelliSense provides two modes for statement completion
Completion mode
Suggestion mode
Useful when using classes and members before they’re defined
Editor shows symbol you type, rather than an entry from list
Use Ctrl+Alt+Spacebar to toggle
In Suggestion mode, code inserts what you’ve typed
Unless you press Tab, which inserts the selected text no matter which mode you’re in

19. Search in Add New Item
Add New Item dialog box includes search mechanism
Type any part of a template’s name
Search does the rest

20. Debugging Improvements
Can add labels to breakpoints
All breakpoints are searchable
Can import/export breakpoints

21. Floating Data Tips Data tips can float in the source window
Floating data tips remain visible until the debugging session ends

22. New C#-only IDE Features
Many user-interface improvements
Two big new C#-only features:
Call Hierarchy
Organization of using statements

23. Call Hierarchy Ctrl+Alt+K (or Ctrl+K, T)
See calls to and from a method

24. Organize Usings Right-click on Using statement
Can delete unused, sort, or both

25. New Language Features

26. VB-Only Features
New features either already in C# 3, or not applicable in C# 4
Implicit Line Continuation
Auto-implemented properties
Collection Initializers
Array Literals
Sub Lambdas
Multi-line Lambdas

27. Implicit Line Continuation
Underscore in Visual Basic indicates that logical line split into multiple physical lines of code
Visual Basic 10 removes the requirement to include the token after certain tokens
If its presence can be inferred
Its use not completely removed
Won’t be necessary in vast majority of cases

28. Implicit Line Continuation
Can be inferred:
After an attribute
After a comma
After a dot (for method invocation or property access)
After a binary operator
After a LINQ query clause
After a (, {, or <%=
Before a ), }, or %>

29. Auto-Implemented Properties
For simple properties that get/set a value with a backing field, can use single statement
Visual Basic creates private field with same name as the property, prefixed with “_”
For property named FirstName, field named _FirstName
You can’t create a variable with this name
Visual Basic creates getter and setter
Cannot have properties, nor can be read- or write-only

30. Collection Initializers
Provide a means of initializing a collection type and providing it with series of default values
Use From keyword to supply list, surrounded with {}
List can be nested
Works for Dictionary, for example
Simply calls Add method of class, passing in information
If no Add method, create your own as instance method or extension method

31. Array Literals Provide a compact syntax for declaring an array
Type inferred by the compiler
Useful when you want to provide default values for an array, and want to allow compiler to determine the type of the array

32. Sub and Multi-Line Lambdas
In Visual Studio 2008, lambda expressions could only consist of a single statement that returned a value, in Visual Basic
Had to be a Function
In Visual Studio 2010, lambda expressions can be a Sub (as well as a Function)
Can also contain multiple statements
Effectively provides anonymous method functionality to Visual Basic

33. C#-Only Features Not many features exclusive to C#
Dynamic language support
Optional and Named Parameters
Dynamic type
COM Interop support

34. Named and Optional Parameters
In order to provide support for dynamic languages
And better support for COM interop
C# 4 supports both named and optional parameters
To indicate an optional parameter, supply a default value
When invoked, can decline to supply a value and use default value instead
No comma counting allowed

35. Named and Optional Parameters
Any argument can be passed by name, rather than by position
Solves the “no comma counting” problem
What do you do if you supply the first and last of a list of 10 optional parameters?
Generally, use two named parameters

36. Dynamic Type
Dynamic lookup allows you to write method, operator, and indexer calls
Property and field accesses
Object invocations
Bypass C# static type checking and instead get resolved at runtime
Required in order to support dynamic languages
Helps with COM Interop

37. COM Interop Support
Many COM methods accept and return variant types, represented as Object in the PIA
Most of the time, developer knows return type
But must explicitly cast returned value
Serious nuisance
Because of dynamic types, can make this easier

38. Ref Parameters Many COM methods contain reference parameters
Generally not meant to change a passed-in argument
Just old-fashioned parameter passing
In the past, C# developers required to create temporary variable for each ref parameter
And then pass each by reference
Now C# compiler allows you to pass parameters by value
Compiler creates temp variables, and discards later
You don’t worry about ref, and called method still gets a reference

39. Parallel Language Features
Dealing with parallel threads in Visual Studio 2008 far too difficult
Difficult to create code, difficult to debug it
Task Parallel Library provides set of public types and APIs
Make developers more productive
Simplifies process of adding parallelism and concurrency
Focuses on the “what” not the “how”
Parallelism only makes sense with multiple processors or processor cores

40. Parallel Static Class When program statements are independent…
… they can be parallelized
StatementA()
StatementB()
StatementC()
Parallel.Invoke(
StatementA(),
StatementB(),
StatementC())

41. Parallel Static Class
In other words, if statements have no shared state, can easily be made to run in parallel
Parallel class provides several useful methods:
Invoke
For
ForEach
Why can’t compiler do this for you?
It has no idea about shared data, or state
Must be opt-in process
Up to you to ensure that statements are independent

42. PLINQ
Technology allows developers to easily leverage multiple cores/processors (manycore)
If using LINQ to objects, requires only a single method call to existing query:
AsParallel
Turns query into a PLINQ query and will use PLINQ execution engine
AsParallel works by returning ParallelQuery (as opposed to IEnumerable)
