Microsoft .Net Technology
- 1. Unit 1 Microsoft .Net Technology
- 2. History • Late 1990’s – Next generation windows services (NGWS) • Late 2000 the first beta versions of .NET 1.0 released • Version 3.0 of .Net framework is included with windows server 2008 and windows vista • Version 3.5 is included with windows 7 • On April 12, 2010 .NET Framework 4 was released along side Visual Studio 2010 • .NET Micro Framework released for mobile and embedded devices.
- 3. History
- 4. .Net based Web standards • UDDI : is a standard on which .NET is based in order to discover and search various Web services.(universal Description, Discovery and Interoperability) • SOAP:defines the standard format to be used when requesting any web service (Simple Object Access protocols) • HTTP: Commincation protocol between various Internet Applications • XML: Defines the format to be used for exchanging data between various Internet applications
- 5. What is .NET? • It is a new environment for developing and running software applications • It provides the framework for an internet- centric industry standard that makes it possible to implement a service oriented architecture by tying together applications, information and data sources using web services.
- 6. What is .NET? • It enables software to become platform and device independent • It employs many standard run time services available to components written ina variety of programming languages • It has inter language and inter machine operability
- 7. .Net • It not a language • It is not an operating system • It is not any network device
- 8. Microsoft Vision • All devices will some day be connected by a global broadband network(Internet) and that software will become service provided over this network. • .NET has been applied to everything from next version of the Windows operating system to development tools.
- 9. Problems before .NET • Registration of COM components: Before installing any application, COM compoenets had to be registered, The window registry becomes more heavy and increase the time of booting process.
- 10. Problems before .NET • Unloading COM components: COM objects also required a special logic for freeing up the objects from memory. This method is known as reference counting of COM objects. • Circular reference exist between two COM componets. So deadlock will occur
- 11. Problems before .NET • Versioning Problem (DLL hell): DLL would overwritten when some other applications were installed on the same computer. It would refer to wrong DLL. This caused a major problem when an application was referring to particular version of a DLL – dynamic link library
- 12. .NET Technology • .Net is the technology from microsoft • .Net platform: 1. .NET Framework 2. .NET Enterprise Servers 3. .NET Building block services 4. .NET Development Tool (Visual Studio .NET)
- 13. .NET Technology
- 14. Features of .Net Platform • Single Programming Model • Distributed Systems • Richer User Interface • Support for multiple Languages • Extendibility • Portability • Intergrity
- 15. .NET Framework • To provide a consistent object oriented programming environment • To provide a code-execution environment that minimize software deployment and versioning conflicts • To provide a code execution environment that promotes safe execution of code and eliminates the performance of the problem
- 16. .NET Framework • .Net framework provides the necessary compile time and run time foundation to build and run .NET based applications • Two main components 1.Common language runtime 2..NET Framework class library
- 17. 1.Common language runtime • Foundation of .Net Framework • It is an agent that manages code at execution time and providing services like memory management, thread management. Also provide safety and code accuracy. • Code that targets the runtime is known as managed code • Code that does not targets the runtime is known as unmanaged code
- 18. 2..NET Framework class library • Develop applications from traditional command line or graphical user interface (GUI) applications such as web forms and XML web services
- 19. Visual studio .NET • Microsoft visual studio is an integrated development environment (IDE) from Microsoft. • It helps programmers create standalone applications, Web applications, Web services and web sites that run on microsoft windows, smart devices and the web • Visual Basic .NET • Visual C++.NET • Visual C#. NET • Visual j#
- 20. .NET LANGUAGES • It has the ability to support multiple languages is one of the primary benefits of the .NET framework. • Enterprises can feel confident investing in the .NET platform • It supports languages in two different ways 1.native language support (VB.NET, C#.NET, VC++.NET, J#.NET) 2.non native or third party language
