Use High Quality Dot Net Framework to Build Robust Applications

.Net Framework offers a high quality, secure and flexible framework. The key success is achieved by making the use of objects. The .NET Framework is recognized for providing secure solutions blended with elevated features.

A robust and flexible security mechanism is the base for a firm foundation of .Net in the competition of web languages. The security model is divided into two categories: code access security and identity-based security.

The code access security (CAS) model depends on code rather than user‘s identity. The policies and permissions are set as per CAS on assemblies according to their publisher, for example, permission granting logic is quite different from user identity of hosting process.

Identity and Principal Objects

The .NET Framework use windows login system. .NET identity-based security relies on two simple concepts: Identity objects and Principal object.

Identity object
An Identity object is basically a user account which exposes three simple properties: Authentication Type, Is Authenticated, and Name.

The .NET Framework comes with four Identity classes:
• WindowsIdentity
• FormsIdentity
• PassPortIdentity
• GenericIdentity

The .Net identity can be compared with windows identity. The standard .NET authorization is same for all kind of Principal and Identity objects, independent of any OS.

Principal object
A principal object is the main object which handles everything. Any .NET class implementing the IPrincipal interface is a valid Principal object. The Principal interface exposes the Identity property and the IsInRole method.

The Principal objects are listed with two libraries: WindowsPrincipal and GenericPrincipal.

Breaking down functionality into small manageable user stories (i.e. functionality) is the best practice, that even helps during the testing phase. You will find it is much easier to write tests, and gradually you will build up a suite of tests for the product.

Why Emphasis on High Quality?

.Net is a product of Microsoft which is always known for its High standards and Quality product. In developing, Net 4.7.1 version, following criteria was set to measure quality:

UI designing – Delivers the expected results in a concise and consistent manner.
Cost Effective Applications – .Net applications are developed with the aim to deliver affordable and maintainable solutions. This is why.Net framework is so prevalent.
Scalability – The bugs and errors can be removed easily.
Extensible – The existing features are not disturbed while implementing new functionality.

A good coding practice, pattern, principle, and tool mentioned above construct .Net 4.7.1 applications. Implementing quality and maintaining UX/UI features will no doubt be an added advantage to your product.

Getting agile by implementing favorable coding practices and patterns leverage every programming language. Your core team members can establish and follow such guidelines.

Create a definition of done

One can’t measure functional quality without specifying acceptance criteria. No user story should be started unless there are acceptance criteria associated with it. The overall quality of the project can be maintained by ensuring functional quality and non-functional quality measures.

Non-functional quality has an impact on the application implementation. Examples of non-functional quality measurements are performance, through put code readability, and test code coverage.

One way to ensure that both functional and non-functional quality is addressed is to create a definition of “done”. This is a checklist for every developer before submitting a task. The following is an example of a definition of done:

The code is written using development standards

• Proper comments are incorporated into the code
• The code must be free of errors and warnings
• The Code should be committed to source control
• To perform testing unit tests must be written and passed
• Minimum code coverage achieved
• No TO DOs should be left in the code
• A review of code should be taken before actually submitting the product

This might seem unattainable to some, but unwavering efforts make it absolutely attainable. If the definition of done is not followed it leads to some form of regret that manifests itself in extra work that you did not plan on doing.

In addition to facilitating the development of next-generation apps and XML web services, .NET Framework also provides developers with an object-oriented code execution environment, that makes it easier for developers to execute code safely, simplify software deployment, and minimize performance issues and versioning conflicts. Many developers prefer .NET Framework because of its inbuilt features to provide rich UX experience.

A continuous modification in .NET Framework allows it to do advanced programming for next-generation. Recently, Microsoft announced .NET Framework 4.7.1 with a number of enhancements and improvements. The developers can also access .NET Framework 4.7.1 as a part of Windows 10. They can even run the latest version of the software development platform on Windows 7+ and Windows Server 2008 R2+.

The latest version of .NET Framework comes with built-in support for .NET Standard 2.0. The developers would not require deploying support files additionally while deploying a .NET application. Some of the features of .NET 4.7.1 version are listed below.

Garbage Collection (GC) Performance Improvement

.NET Framework 4.7.1 improves memory allocation performance of applications by making several changes to garbage collection (GC). The architectural changes made to garbage collector boosts the performance of .NET applications by dividing larger object heaps into a number of small objects heaps. Hence, an application can easily reduce allocation lock contention by avoiding large object heap allocation.

Configuration Builders
The latest version of .NET Framework enables developers to build and inject configuration for applications at runtime through configuration builders. The developers can use configuration builders to pull data from various sources dynamically at runtime. They can even use configuration builders to apply the custom-defined set of builders to specific configuration sections and make changes to the data of specific configuration sections.

ASP.NET Forms Authentication
While working with ASP.NET, developers often store user credentials with hashed passwords in configuration files. .NET Framework 4.7.1 makes it easier for developers to enhance the security of user data by using more secure SHA-2 hash options. Despite being compatible with SHA-1, SHA-2 adds a number of new hash options to .NET Framework — 256, SHA-384 and SHA-512.

ASP.NET Execution Step Feature
ASP.NET processes requests through its own pipeline which includes 23 events. It further executes an event handler as an execution step. .NET Framework 4.7.1 avails a new feature called ExecutionStepInvoker by which you can directly execute the code. The programmers can use ExecutionStepInvoker to run the execution steps in the code instead of pipeline. They can even take advantage of this new feature to manage the libraries required for the application’s execution to flow efficiently.

ASP.NET HttpCookie Parsing
.NET Framework 4.7.1 provides a new ASP.NET API called HttpCookie.TryParse. The developers can use the API to create HTTPCookie object from a string in a standardized way. The API even allows developers to capture key properties of a cookie — path, expiry date, and secure indicator accurately. The ASP.NET developers can take advantage of .NET Framework 4.7.1 HttpCookie.TryParse to simplify creation and manipulation of HTTP Cookie objects.

Compiler Improvements
.NET Framework 4.7.1 comes with several improvements to boost the compiler performance. It facilitates binary serialization by making a System. ValueTuple types as serializable. It further provides initial support for a new C# 7.2 language feature — ReadOnlyReferences. At the same time, the runtime improves the performance of applications by making .NET Framework support Portable PDBs. The developers can even use a new API to check if a particular feature is supported by a specific runtime. The compiler will consume the API, and check if a feature is supported at runtime. Hence, developers can accelerate code compilation by knowing the compatibility of a feature with specific runtimes.

Accessibility Improvements
The accessibility improvements included in .NET Framework 4.7.1 aims to keep various libraries compatible and accessible. The latest version of .NET Framework further improves the accessibility of Window Forms by extending UI accessibility pattern, improving display in high contrast mode, and enhancing screen narrator. The improved tools included in WCF SDK further improve keyboard navigation and keyboard focus order.

New WPF Features
.NET Framework 4.7.1 accelerates desktop application development by providing a number of new Windows Presentation Foundation (WPF) features. The developers can update elements automatically each time the resource changes by using implicit data templates. They can even implement a new method to check if the value obtained from the data template is dynamic or static. They also have the option to make a WPF application share its internal information using the Visual Diagnostics features.

Conclusion: –
.NET Framework 4.7.1 can be downloaded and installed through web installer and offline installer. Microsoft even allows developers to download .NET Framework 4.7.1 runtime and dev pack for Visual Studio. Hence, the .Net developers can easily take advantage of the improvement provided by .NET Framework 4.7.1 without putting extra time and effort. The .Net 4.7. 1 can maintain the high quality applications with fully secure options.
