Aspects of ASP.Net framework – Crucial ones

One of the most crucial aspects of ASP.NET application is to extend support to the websites as well as projects that involve web based application. Hence, it can well be mentioned that the default application of ASP.NET is to provide a good template for a starter project like Master Page that comes up with a standard template, an “About Us’ page, a ‘Login’ page, a ‘register’ page, a ‘Change Password’ page, etc. Continue reading Aspects of ASP.Net framework – Crucial ones

Angular JS and ASP.Net – Why is It a Deadly Duo?

ASP.Net MVC is hugely popular among web developers who want to keep the business logic, data and presentation logic. The feature further makes it easier for enterprises to develop complex and large web applications through distributed teams. But programmers often try to save both time and effort by combining ASP.Net with a variety of innovative technologies like Angular JS.

As a client side MVC framework in JavaScript, Angular JS was originally developed by a group of developers at Google. Within a shorter span of time, open source framework become hugely popular among developers due to loads of features and the support of a vibrant community. If you are planning to use Angular JS on top of ASP.Net, it is important to understand what makes it a deadly duo.

What Makes the Combination of Angular JS and ASP.Net Deadly?

Model View View Model (MVVM)
As a new paradigm, MVVM has become hugely popular among web developers within a shorter time span. According to MVVM paradigm, JavaScript is used to make the Model and View stuff exist in the client side. Thus, the Model and View stuffs are not required to be processed on the web server through postbacks. JavaScript frameworks like Angular JS make it easier for programmers to keep the frontend separate from the backend data rendering logic. Angular JS can be used to modify the Model, and make the changes reflect in the View immediately. Likewise, the manual changes or user input to the View will also reflect in the Model immediately.

Inject Parameters into the Controller
Angular JS can also be used on top of ASP.Net MVC to inject parameters like $http and $scope into the Controller. The programmers can place the Model in $scope. Similarly, $http can be used to facilitate low-level HTTP communications. Thus, the programmers can simply call a Web API controller on the server to retrieve list of audio, videos or other content into the $scope. As Angular JS can detect the changes in the Model, it can use {{ }} templates to generate output using the information.

Effectuate Development of Single Page Applications
Many enterprises, nowadays, opt for single page web applications to quickly convey the relevant information to users. The combination of ASP.Net and Angular JS will make it easier for developers to build single page applications. They can further use Visual Studio IDE + Visual Studio Online to create the application by using a set of out of the box tools. Along with an efficient code editor and debugger, they can further avail tools like agile/scrum planning, continuous integration, automated deployment, Git source control ad Windows Azure dev tools. Further, the combination will enable them to optimize the application’s performance by using the required components and libraries provided by a single vendor.

Make the Web Applications Easy to Test
The developer can easily test the web applications by combining Angular JS and ASP.Net MVC. They can use the tools provided by Visual Studio IDE + Visual Studio Online to carry out load testing, unit testing and UI testing in the MS Test. At the same time, they also have option to use a variety of testing frameworks like NUnit. The testing framework can be downloaded directly or through the Nuget Package Manager command. Once the testing framework is installed and configures, testing professionals can run test cases directly from the Test Explorer.

The developers have option to create robust web application by using Angular JS in a number of ways. However, they must remember that meaning of key concepts like Models, Views, Controllers and Routes is different in context of ASP.NET MVC4 framework and Angular JS. So the programmers must understand the differences to create complex web applications by taking advantages of the deadly duo.

What makes .Net more preferable than PHP?

PHP or Hypertext Preprocessor was originally a scripting tool which due to its large developer community and easy learning curve, took over the internet by storm in a short matter of time. This free tool has a huge number of frameworks that can simplify web development. Microsoft developed ASP.NET so that developers can take advantage of an easy scripting tool to build web applications as well as pages. This ASP’s successor can be coded by using any of the languages that is .NET supported, making it really popular amongst the developers. Now, when it comes to selecting the language we face a huge dilemma about which one to choose from these two. Given below are some sections and how both software fare in those categories.

custom .net development companyScalability along with maintenance- In this respect, there can be no winners as both are equally scalable. In fact, how easy the maintenance as well as scalability becomes, is dependent on the experience of the programmer, proper standards as well as guidelines for programming being followed, which programming practices along with frameworks are being used, etc.

Costs- This is one section where PHP is the clear winner since it is totally free. When using the Microsoft product, some costs are associated like you have to have Windows as the development can be made on Windows machine only; Windows hosting along with IDE or Integrated Development Environment is also required. For example Visual Studio is the most popularly used IDE. Beginners do not have to shell out specifically to use .NET. However, those who have upgraded to professional stages need Visual Studio and such other tools which may turn out to be expensive. However, the free PHP running on Linux web hosting may be used on Linux, Mac or Windows. A number of paid as well as free IDEs support it.

Speed as well as performance- In most cases, this subject has been the topic of much debate. The debates often come as biased so that one language can be promoted over the other. When you measure the speed of a web application there are plenty of factors to keep in mind. So, most often programming languages do not have any specific or noticeable effect on the performance as well as speed. However, when enormous tasks need to be performed then some factors should be considered before making the big decision to choose the software that is best suited for the scenario. In some respects, PHP performs slightly better than .NET but the effect is quite marginal.

Availability of editors along with tools- PHP developers mostly prefer to use text editors such as Notepad++ and Vim, instead of full-fledged IDE. But those who prefer to use IDE can find solid support in free editors such as Eclipse. Most IDEs also supported ASP.NET but Visual Studio is the most preferred one. In fact, the features as well as benefits offered by using Visual Studio is the most pronounced.

Portability- Both office along with web applications may use .NET framework but PHP works only on the web. However, you can insert as well as run JAVA code within it through Java JRE installation on webserver which may prove to be cumbersome.

Language support- A vast variety of development languages are supported by .NET. However, only JAVA and PHP language itself are supported by PHP.

Web services- In this category also .NET is definitely most preferred over PHP since the best features are available in this language for the building of useful web services. In fact, the entire building process is also really simple when compared to other present frameworks.

Security- The framework integrated with effective security mechanism to save many programming makes ASP.NET framework again more preferable.

There are individual advantages to both the above mentioned frameworks and the ultimate decision should be made after careful consideration of the individual requirements. However, when it comes to building of multi-featured applications, ASP.NET framework gains a slight edge over PHP. If you are willing to incur some initial costs then you will be left with an application that has a plethora of features along with zero security concern.

ASP.Net – Powering Mobile Apps With Responsive Design

Each and every modern business, irrespective of whether it is of small, medium or large scale, would require a dedicated portal that is specifically designed to promote the products or service that the business delivers. Today, for any company, it is highly imperative that it does not stick to any static site for promoting its business.

expert asp.net developersInstead, they venture out over other avenues of marketing for effective promotion of product and services. In the era of Internet based technology and social media, it is a ‘must’ for every company to reach out to the modern tech savvy clients who very much expect businesses to offer the latest as well as the best portfolio online, in every possible way over every possible device that is compatible to an internet connection. Therefore, the need of the hour is to provide information over phones, tablets, as well as other devices which have higher resolution than the screens of the conventional PCs and laptops.

Now the question is – how that can be done? Before we get into the technical nitty-gritty of responsive web design and ASP.NET, let us at first know what responsive web design actually is. It is actually a specific type or concept of web design that can help the site to fit into any type of device irrespective of its screen size. For example, a web site that is responsive can be displayed on a PC as well as an iPhone in spite of the fact that the screen of the iPhone is much smaller than that of the PC. Yet, none of the contents of the website will be lost in either of the versions.

In other words, responsive web design is a series of mechanisms that will allow a particular web page to adapt to the capabilities of a client which may include a human as well as an electronic consumer.

RWD techniques respond to:

– The capabilities of browsers (HTML5, plugins, native audio and video, CSS3)
– Device capabilities (geo-location, input methods, resolution)
– User Capabilities (vision and hearing)
– Viewport (media type, orientation, resolution, density)

When it comes to responding to these techniques, ASP.NET is the answer. When a user requests a web server to carry out any task, the command passes along the information regarding the client who is making that request. ASP.NET, by using that information can make certain determination regarding the nature or the type of device that is being used to make the request. This web application framework comes up with a unique httpRequest.Browser.IsMobileDevice property, which helps it to detect the device and take actions accordingly.

The browser object also comes up with certain other properties – MobileDeviceManufacturer or MobileDeviceModel that help in detecting critical information regarding that device. ASP. NET is designed to provide certain additional properties that help it to detect specific details regarding a particular device. However, it does not have any complete list of all the standard properties that a device comes up with. However, the .NET community has come up with certain extremely useful projects that negate this shortcoming and help a website to accurately pick up any mobile device.

One of the projects, known as Wireless Universal Resource File (WURFL), is actually a database of various mobile devices. The database includes the name of the device, information about the user agent, the height as well as the width of the device screen, whether it is a mobile or tab. If it is a mobile, the mobile browser type and version it uses and so on. The database is regularly updated at short intervals. This makes ASP. NET one of the best ways to design and develop websites that are responsive.

Responsive web design has been here for quite a few years. With its popularity increasing by leaps and bounds, the concept is continually gathering steam from every quarter. Hence, careful evaluation backed by a clinical approach with the help of platforms like ASP.NET will further sharpen responsiveness of the sites.

How to use the new CORS support in Web API 2

Many exciting new features have been enabled in ASP.NET Web API 2. This framework enables easy building of HTTP services which will reach many clients across a broad spectrum including mobile devices as well as browsers. The addition of several features has idealized this platform.

Some of the most remarkable features are attribute routing(on top of convention-based routing), Open Web Interface for .NET or OWIN self hosting, Web API Odata, IhttpActionResult and the most significant is the Cross Origin Resource Sharing which has taken the cyber world by storm.

asp.net developersCORS is the short form of Cross-Origin Resource Sharing; this standard allows web pages the ability of making Ajax requests to other domains. Same-origin policy which has been implemented on browsers is relaxed; previously this policy limited calls to be just within same domain with cross-domain calls not being allowed. CORS defines the interaction of the browser along with server so that cross origin calls can be made. API supports this in its 2nd version and it is compliant with standards of W3C.

CORS is already supported by majority of modern browsers. But if we want to enable support for API services, first of all we will be needing a few assemblies to ensure that this is done smoothly. We will need System.Web.Cors.dll which is not dependent on System.Web.Http.dll or System.Web.dll and contains core CORS library; System.Web.Http.Cors.dll which contains CORS enabling library on Web API which is dependent on System.Web.Http.dll as well as System.Web.Cors.dll.

When upgrading and installing the package from nightly builds, the first thing that you have to do is create new API project by starting with new template.

Since you do not need Microsoft.AspNet.Mvc.FixedDisplayModes package, the second step is to uninstall it. In fact uninstalling this is necessary as you will be prevented from updating to recent nightly build.

The 3rd step is installing Microsoft.AspNet.WebApi.Cors package from nightly builds. Set the package source and it will enable you to see CORS package.

After that, the 4th step is to fix binding redirects that are there in web.config, otherwise there will be errors. which is existing must be replaced which will enable the smooth running of the applications.

After that you can try it out by browsing test clients available on some sites and making a fast cross-origin request. You will find Test APIs and all you have to do is click there and paste the URL on your API. Click “Send” and it will show request failed since CORS is not enabled on API by default. Now you have to enable CORS by calling config.EnableCors (new EnableCorsAttribute()). Now you have enabled CORS for all controllers and all origins will be allowed.

While we enable this a few scenarios should be considered. While enabling this, HttpConfiguration has a new method of extension added to it which will enable global support per action or per controller.

When calling EnableCors, global settings can be defined. For example we can enable the sharing globally which will allow all headers, origins and methods. EnableCorsAttribute has many settings which are easy to configure. The controller can be scoped with the support as well. You just have to call EnableCors without the provision of a global setting. Then the EnableCorsAttribute can be declared so that the controller is enabled with the support. It can also be enabled on single action in a similar manner.

An action or controller can be excluded from EnableCors as well simply by using DisableCors attribute. Custom IcorsPolicyProvider can be implemented as well so that policies or settings related to the support from other sources can be loaded dynamically.

One thing to remember when testing this with IE is that the port is not considered by IE as part of Security Identifer or the origin which is used for enforcement of Same Origin Policy. So test clients and Web API on different local hosts will hinder cross-origin requests.

Difference betweeen WebForms and MVC – CodeProject

ASP.NET MVC and ASP.NET WebForms are the two existing essential development models that highly contribute to the technology enhancement of today’s hi-tech era. Both these models have some pros as well as cons which will be discussed here in the light of comparison.

What are WebForms?

.net application developmentASP.NET WebForms were first brought out by Microsoft from ASP. It solved a number of problems by creating abstraction of higher level over simulated stateful model and stateless web for web developers.

  • WebForms introduce applications like self postback (post to same page form data) or ViewState (during postbacks maintain control values).
  • The most interesting part lies in the fact it is not required to even a single line of code. With the emergence of Web Forms, Microsoft attempted to bring forth the Visual Basic model into web.

What is MVC?

For sometimes now the concept of MVC has been around after Microsoft introduced it. It is actually an architectural pattern and including Java it is also used by a number of developers. ASP.NET MVC is an important model required for web applications and this pattern is a solution to a context related problem. This application offers input logic, UI logic and business logic. It allows you to develop an application loosely coupled between each of such elements.

The main purpose of this pattern includes separation of concerns. It makes UI ignorant or presentation of user interaction and business logic. According to this pattern, system is divided as Model (M), View (V) and Controller (C).

  • Model, considered as smart is meant to handle the logic or data as well as Business rules and will remain independent of the other MVC parts like Controller or View.
  • In short, controller receives as well as dispatches the request while handling the user interaction or input logic. It knows everything about View or Model.
  • A view is regarded as dumb and it is the output representation of a model data. It can be a web page or an excel sheet, showing just a simple text or list of records. View only knows about Model.

Difference between WebForms and MVC

Here are some of the very basic differences between these two major applications responsible for website development.

  • WebForms use the page controller approach for the purpose of rendering a layout. Whereas, MVC offers a model which has no connection with the View, hence it becomes easier to maintain or test the applications.
  • For all the pages, Web Forms use the front controller pattern in order to process the web application requests. It is also used to generate routing architecture. Where as, MVC has the View which is called before the controller that is used to provide the View, based on the action as there is interaction between user and the interface.
  • Web Forms use the server based controls along with view state for managing the state of the model. MVC does not record state information unlike Web Forms.
  • WebForms are basically event driven whereas, MVC is test driven.
  • In case the development team is small, Webforms are mostly preferred for Rapid application development. MVC is best suited for larger project where more priority is given to testability or maintainability.
  • It is easy to learn Webforms development in comparison to MVC development.

Irreplaceable depending on certain requirements

ASP.NET MVC or ASP.NET WebForms, each could be the best choice for any particular solution. Depending on the requisites of an application along with the background of the team professionals involved, both the technology can serve the best purpose for your business prospective. Hence, one application can never replace the other.
