2. What is .NET Framework?

3. With .NET framework you can create
Console applications.
Windows GUI applications (Windows Forms/WPF).
ASP.NET applications.
XML Web services/WCF.
Windows services.
Mobile Applications
Office Add-inns
Silverlight applications

4. Architecture of .NET?

5. Common Language Runtime (CLR)

6. Additional CLR services
Memory management
Thread management
Exception handling
Garbage collection
Security

7. Base Class Library Is a collection of reusable types
Is a foundation on which .NET applications, components, and controls are built
Is object oriented
Custom code can derive functionality from base classes
Custom code can implement provided interfaces
All types are organized into namespaces

8. Base Class Library types:
Represent base data types and exceptions.
Encapsulate data structures.
Perform I/O.
Access information about loaded types.
Invoke .NET Framework security checks.
Provide data access, rich client-side GUI, and server-controlled, client-side GUI.

10. Common Type System
Establishes a framework that helps enable cross-language integration, type safety, and high performance code execution.
Provides an object-oriented model that supports the complete implementation of many programming languages.
Defines rules that languages must follow, which helps ensure that objects written in different languages can interact with each other.

11. What are Assemblies? Building blocks of .NET Framework applications
Collection of types and resources are built to work together and form logical unit of functionality
Fundamentas unit of
deployment,
version control,
reuse,
activation scoping,
and security permissions
To the runtime, a type does not exist outside the context of an assembly.
In simple words: execs, dlls
One Visual Studio Project > one Assembly

12. Runtime Hosts
ASP.NET (WebServer)
Browser
Office applications
Shell exceutables (console, GUI)

13. ASP.NET Supports creating Web Apps Mobile Web Apps MVC apps
Web Services

14. ADO.NET
* Types for supporting MS SQL and other database access

15. Win Forms / Windows Presentation Foundation
Full set of libraries for creating classic or media rich client applications

17. What was new in .NET Framework 3.0?
The programming model, runtime, and tools for building long-running, persistent, workflow- and rules-based applications
Windows Presentation
Foundation (WPF)
Windows Workflow Foundation (WF)
Windows Communication Foundation (WCF)
A framework for building user interfaces for applications and media-rich experiences
An interoperable framework for building connected applications, with a focus on service orientation and Web services

18. What is Microsoft .NET Framework 3.5?
The 5th version of the Microsoft .NET Framework
Fully supported in Visual Studio 2008
Builds incrementally on .NET Framework 3.0 SP1, which was built on .NET Framework 2.0 SP1
Microsoft Visual Studio 2008
.NET Framework 3.5
.NET Framework 3.0 SP1
.NET Framework 2.0 SP1 18

19. What’s new in .NET Framework 3.5?
WPF WF
WCF
Language Integrated Query (LINQ) for SQL-like data querying
Integrated support for ASP.NET AJAX and new Web Services standards …. 19

20. What’s new in .NET Framework 3.5?
WPF WF
WCF
LINQ provides SQL-like data-querying capabilities
Language extensions to C# and Microsoft Visual Basic® that add native data querying capabilities, using a syntax like SQL
Support is deeply integrated throughout .NET Framework 3.5 runtime, compiler, and class libraries
Lets you write code in any LINQ-enabled language to query and filter objects, SQL databases, DataSets, and XML by using a SQL-like syntax
Enables increased programming productivity and simpler, easier-to-maintain code 20

21. LINQ Examples

22. What’s new in .NET Framework 3.5?
WPF WF
WCF
Support for building Web 2.0-style applications
Integrated ASP.NET AJAX support with JavaScript Object Notation (JSON)
Enabling support for Web programming models such as Plain Old XML (POX), Representational State Transfer (REST) and syndication feed format such as Really Simple Syndication (RSS) and ATOM. 22

23. What’s new in .NET framework 3.5 SP1
ADO.NET Entity Framework (ORM)
ASP.NET Dynamic Data

24. .NET Interoperability
Mono project : .NET port for Linux
