Understanding .Net Framework 4.5 Architecture

ASP.NET is used to build rich internet-based web applications. The .NET web application runs on a server with Internet Information Services (IIS) installed. IIS processes the application, sends the result to the client, and displays the output in the user's browser.

• ASP.NET in .NET Framework 4.5 is used to build dynamic and interactive web applications.
• ASP.NET supports server-side processing, making websites faster, more secure, and easier to manage.

8. Windows Store Apps (Metro Style Apps)

A Windows Store app is a new type of application that runs on Windows 8 devices and can take advantage of new WinRT APIs. These can only be distributed in the Windows 8 store.

• Windows Store Apps (Metro Style Apps) in .NET Framework 4.5 are designed for touch-friendly and modern user experiences on Windows devices.
• These apps run in a sandboxed environment, making them secure and ideal for distribution through the Windows Store.

A Windows Desktop app is a traditional Windows Forms application with a new name. Software developed for Windows XP, Windows Vista, and Windows 7 will be categorized as a Windows Desktop app when running on Windows 8. Examples of Windows Desktop apps are Microsoft Office family products, notepads, etc.

• Desktop Apps (Windows Forms) in .NET Framework 4.5 are used to create rich, user-friendly applications for Windows desktops.
• Windows Forms provides built-in tools and controls to quickly design and build graphical user interfaces.

10. WPF

WPF is used to create applications with a rich user experience. It includes application UI, 2D graphics, 3D graphics, and multimedia. It takes advantage of the hardware acceleration of modern graphics cards. WPF makes the UI faster, scalable, and resolution-independent.

• WPF (Windows Presentation Foundation) in .NET Framework 4.5 is used to create visually stunning desktop applications with advanced graphics and media support.
• WPF allows developers to build rich, interactive UIs with data binding, animations, and 3D graphics for a seamless user experience.

11. Silver Light

Silver Light is a cross-browser web-based technology that allows designers and developers to deliver Rich Internet Applications (RIA) embedded in Web pages.

• Silverlight in .NET Framework 4.5 is a framework for building interactive web applications with rich media, graphics, and animations.
• It allows developers to create cross-platform web apps, though its use has been phased out in favor of modern web technologies like HTML5.

12. ADO.NET

This is used to create a Data Access Layer to query and manipulate data from underlying data sources like SQL Server, Oracle, DB2, etc.

• ADO.NET in .NET Framework 4.5 is used to connect to databases and retrieve and manipulate data in applications.
• ADO.NET provides a set of classes for handling data operations and ensures fast and efficient data access in web and desktop applications.

13. LINQ

This allows you to query the data from various data sources (like SQL databases, XML documents, ADO.NET Datasets, Various Web services, and any other objects such as Collections, Generics, etc.) using a SQL Query syntax with .NET framework languages like C# and VB.

• LINQ (Language Integrated Query) in .NET Framework 4.5 allows developers to query data from different sources like databases, arrays, and XML using simple, readable syntax.
• LINQ integrates query capabilities directly into C# and VB.NET, making it easier to work with data in a more efficient and declarative way.

14. ADO.NET Entity Framework

ADO.NET Entity Framework is used to query and store data in relational databases (like SQL Server, Oracle, DB2, etc.) in an ORM fashion.

• ADO.NET Entity Framework in .NET Framework 4.5 simplifies database interactions by allowing developers to work with data using objects instead of SQL queries.
• It provides an object-relational mapping (ORM) layer, making it easier to query and manipulate data from a database in a more intuitive and object-oriented manner.

15. Parallel Extension

Parallel Extension allows you to distribute your work code across multiple processors to take advantage of the hardware.

• Parallel Extensions in .NET Framework 4.5 enable developers to write parallel and asynchronous code, improving the performance of multi-core processors.
• It provides APIs like Parallel.For and Parallel LINQ (PLINQ) simplifies the development of applications that perform multiple tasks simultaneously, making them more efficient.

16. WCF

This is used for building and developing services based on WS-* standards.

• WCF (Windows Communication Foundation) in .NET Framework 4.5 is used to build secure and reliable service-oriented applications for communication across different platforms.
• WCF supports various communication protocols, making it ideal for building distributed applications, web services, and enterprise-level solutions.

Asp .Net Web API is a framework for building HTTP services that can be consumed by a broad range of clients, including browsers, mobiles, iPhones, and tablets.

• ASP.NET Web API in .NET Framework 4.5 is used to build HTTP-based services that can be consumed by various clients like browsers, mobile apps, and other devices.
• It allows developers to create RESTful APIs with support for multiple formats, including JSON and XML, making it ideal for building scalable web services.

ASP.NET SignalR is a library that simplifies the process of adding real-time web functionality to applications. Real-time web functionality is the ability to have server code push content to connected clients instantly as it becomes available, rather than having the server wait for a client to request new data.

• SignalR in .NET Framework 4.5 is used to add real-time web functionality, like chat apps or live notifications, to your applications.
• SignalR automatically manages connections and allows instant data updates between the server and client without needing page refreshes.

19. WF

WF (Windows Workflow Foundation) is used to build a process-oriented business workflow and rules engine.

• WF (Windows Workflow Foundation) in .NET Framework 4.5 is used to create workflows that define and manage the steps in a business process or application logic.
• WF provides tools to design, implement, and execute workflows, making it easier to automate tasks and integrate complex processes in applications.

The Visual Studio IDE offers a set of tools that help you write and modify the code for your programs, and also detect and correct errors in your programs. Using Visual Studio 2012, you can build Windows Store apps, desktop apps, mobile apps, ASP.NET web apps, and web services.

• Visual Studio 2012 is the primary IDE for developing applications in the .NET Framework 4.5. It offers powerful tools for coding, debugging, and designing user interfaces.
• It supports multiple programming languages, such as C # and VB.NET, and provides built-in templates for web, desktop, and service-based applications.

Conclusion

In conclusion, the .NET Framework 4.5 is a powerful and flexible platform that allows developers to easily build a wide range of applications, whether desktop, web, or back-end services. With strong features and cross-language support, .NET Framework 4.5 makes application development faster, safer, and more efficient.
