.NET framework is the parent software behind every application created for mobile platforms, windows apps, and web services designed using the .NET Framework. These tools help greatly in the development and support of mobile device development with ASP.NET Mobile controls (previously known as Microsoft mobile development toolkit).

The .NET framework provides a code-execution environment for removing the scripted or interpreted environments and fixing performance issues and promoting the safe execution of codes for multiple types of applications created by third parties and unknown. It also comes with its own set of preloaded libraries (user interface, network connectivity, data access, and more)

It can combine into several programming languages that can be set into motion and can be executed inside a common application virtual machine that manages common features such as exception handling, memory management, security, and more. This combination between common language runtime and class libraries is what we know as .NET Framework.

.NET Framework 3.5 provides scalability, HTTP Pipeline, and syndication feeds and optimized performance combined with AJAX support and more using the integrated codes based on the .NET Framework for a wide variety of apps ranging from Mobile, Web, and Windows-based apps. Read on more to know what else .NET Framework 3.5 has over its previous versions and how does it help in running applications and supported architecture.

How does the .NET Framework works?
In simple terms, .NET Framework contains common language runtime (CLR) as well as the .NET Framework class library. To be more accurate just think of the runtime as the core lifeline that plays an important role in managing code at execution time all the while running its main services such as memory management, remoting, and thread management. Taking all that into consideration it also executes strict type safety and other forms of code accuracy that strengthen security and optimizations.

The runtime also paves way for the developer's productivity. The reason being developers make full use of the class libraries, runtime, and components compiled by other developers in different languages. Improving the allocating process for existing apps.

The release of .NET Framework 3.5
.NET framework’s 3.5  version was released commercially to the public on 19 November of 2007 available for Windows operating systems such as Windows 2000, 98, NT, Me, and finally Windows XP. But its most important update brought back CLR of version 2.0, same as its previous iteration 3.0 as well as several other framework packages like .NET Framework 2.0 SP1, .NET Framework 2.0 SP2 with 3.5 SP1. Which expands the properties of BCL Classes in 2.0 and adding some methods to function 3.5 version features such as Language Integrated Query (LINQ). This update offered the entire framework into a software development kit package with bundles of different .NET Framework packages.

Version 3.5 allowed the developers from all around the world for experimenting, optimizing and deploying windows applications, creating as well as implementing support for security changes, paging support for ADO.Net, and built-in support for ASP.NET AJAX. All of these offered improvements and provided a much more comfortable environment for managing projects of large and small scale mobile apps, web applications, windows apps to larger business projects.

Key features of .NET Framework 3.5

  • Windows Communication Foundation (WCF)
  • RSS and ATOM Support
  • New graphic features
  • Data awareness
  • Windows Presentation Foundation (WPF)
  • Workflow foundation
  • AJAX Support
  • Support for Language Integrated Query and Extensions

.NET Framework class library features
.NET Framework class library offers a group of reusable types to third parties or unknown developers that strictly blends with the common language runtime. Not only does this makes it very easy to use the .NET framework given how it derives the functionality of its own managed codes but it also makes the third-party applications integrate with classes in the .NET framework without any issues whatsoever.

And as one can expect from an object-oriented class library, the .NET framework class gives the developers the ability to achieve common programming tasks, including file access, database connectivity, string management, and data collection.

Features of the common language runtime
Common language runtime comprises runtime that manages code execution, memory, compilation, code safety verification, thread execution, and other system services. These features are core elements to the managed code that run on the common language runtime.

When it comes to security managed components are given a specific degree of trust. Depending on many factors that include their origins such as enterprise network, internet, or local computer. Meaning that the managed components might or might not be able to perform their intended operations such as registry-access operations, file access operations, or any other sensitive operations even if it’s used in the same active app.

The runtime's primary purpose is to load, execute, and strengthen code’s robustness by enabling a strict type and code verification infrastructure known as a common type system (CLR). The CLR ensures that all the managed codes are compiled to Microsoft's new intermediate byte code format called Intermediate Language (IL). Various language compilers whether it be from Microsoft or third-party generate codes that respond to the CLR. Implying that the managed code can utilize other managed types and instances, while strictly implementing type safety and type fidelity.
