What is ADO.NET?

This article holds some important information and introduction to ADO.NET (ActiveX Data Objects for .NET). ADO was for the first time released in 1996 and it represented a new way of dynamically retrieving data from any database in ASP.NET programming.

ADO.NET is an object-oriented set of libraries that allows you to interact with data sources. Commonly, the data source is a database, but it could also be a text file, an Excel spreadsheet, or an XML file. But overall, it is used as a way to interact with a data base. ADO.NET is sometimes considered an evolution of ActiveX Data Objects (ADO) technology, but was changed so extensively that it can be considered an entirely new product.

Thus, ADO.NET is the .NET technology for programmers to interact with data sources. You have several Data Providers, which allow communication with different data sources, depending on the protocols they use or what the database is.

Common ASP.NET Application Security Flaws

For highly secure ASP.NET Web applications, such as Internet banking sites, you may want to implement a more secure solution for user authentication than the user name and password combination. You can use client-side digital certificates to verify the identity of the user. In addition, you can map client-side digital certificates to Windows accounts on the server if necessary.

There is a wide array of attacks that ASP.NET web applications need to protect against but most security holes are due to flaws in the following:

Authentication... makes easier for attackers to reveal the User’s credentials, or worse to dig down the application’s authentication altogether. The secure password policy, brute force attacks and password hashing are the part of authentication mechanism.

Authorization… Allowing logged-in users to perform actions without authorization verification. This can possibly be ensured with all ASP.NET web pages in a consistent manner.

Data validation… is all about trusting data submitted by the User and then acting upon it. It is generated by the lack of data consistency throughout the web, and failing to encode the data sent to the server.

App configuration… is about using some default configuration on the application and hosted server. Different applications require different configurations but the focus of this section is on those that fall under the responsibility of the web developer.

Managed Code in ASP.NET

In ASP.NET programming, the term Managed Code is used to describe the code that will execute only under the management of a Common Language Runtime Virtual Machine. In the same reference to context, the code that does not depend on the Common Language Runtime is known as unmanaged code.

Increased security, and structured and convenient code are the main benefits of managed code. Moreover, it also supports in process of quality assurance practices in process of ASP.NET programming.

The code which is not managed can bypass the ASP.NET framework and make direct calls to the operating system. A point of concern here can be like the Managed code cannot be accessed outside of the runtime environment. It also cannot call any function directly outside the runtime environment.

Exception Handling in ASP.NET

Exceptions or errors are unusual occurrences that happen within the logic of an application. The CLR has provided structured way to deal with exceptions using Try/Catch block. While errors occur in ASP.NET programming, they either get handled or needs re-look at the code. While an unhandled exception propagates, the User may be redirected to an error page using different ASP.NET configuration settings.

The programmers can control the exceptions that get thrown and prevent a redirection. Error or exception handling in ASP.NET can be further categorized into 2 categories as below:

• Handling exceptions as and when they are thrown
• Redirecting the User to an error page when errors go unhandled

Logically, as a ASP.NET developer, you cannot program for every possibility. Hence, they are imminent.

Metadata: Concept in ASP.NET programming

Metadata – typically means the data within the data files. With reference to ASP.NET programming, meta data is the binary information which describes the characteristics of a resource. This information includes the description of the Assembly, data types and members with their security permissions, declarations, implementations, references to other types and members, etc.

In ASP.NET programming, the metadata describes all classes and class members that are defined in the assembly, and the members which the current assembly will call from another assembly. Moreover, the metadata eliminates the need for interface definition language (IDL) files, header files, or any external method of component reference.

During the compilation of any program, both the metadata and MSIL are together wrapped in a Portable Executable files. Now, when the program is running, the JIT compiler of CLR uses the metadata and converts the MSIL into a native code. And when the code is executed, the runtime loads metadata into memory and references it to get the information about the code’s classes, members, inheritance, and so on.

ASP.NET Strong Names

In ASP.NET programming terms, a strong name consists of the assembly's identity — its simple text name, version number, and culture information (if provided) — plus a public key and a digital signature.

In particular, strong names satisfy the following requirements:

They guarantee name uniqueness by relying on unique key pairs. No one can generate the same assembly name that you can, because an assembly generated with one private key has a different name than an assembly generated with another private key.

Strong names protect the version lineage of an assembly for ASP.NET programmers. It can ensure that no one can produce a subsequent version of your assembly. Users can be sure that a version of the assembly they are loading comes from the same publisher that created the version the application was built with.

Strong names provide a strong integrity check. Passing the .NET Framework security checks guarantees that the contents of the assembly have not been changed since it was built. Note, however, that strong names in and of themselves do not imply a level of trust like that provided, for example, by a digital signature and supporting certificate.

Satellite Assembly in ASP.NET Programming

A compiled code library used for deployment, version, and security is known as assembly in ASP.NET programming terms. A single assembly can consist of one or more files. Microsoft’s Visual Studio does not support using different languages in one assembly.

A classic .NET framework assembly contains resources specific to a give programming language. With usage of the satellite assemblies, one can place the resources for different languages in different assemblies. The correct assembly s then loaded into memory only if the User selects to view the application in that language. Overall, the assemblies must contain culture-neutral resources. If as a ASP.NET programmer, you want to localize the assembly, then you should go for satellite assembly.

A process assembly represents a process that will use classes defined in library assemblies. There are basically two types of assemblies: process assemblies (.exe) and library assemblies (.dll).

Multithreading in ASP.NET

In ASP.NET programming, there are indeed many operations which demand to run in parallel with the main code, but demand very high CPU usage. The examples include acquiring a database and waiting for the results, any heavy 3rd party software integration, etc. – hence, here the ASP.NET programmers are suffering a heavy and loaded input/output operation. Thus, the application will be dead with no response until this time consuming operation completes.

A common solution for this problem in ASP.NET programming in multithreading.

Multithreading is a technique that can be used to perform time consuming tasks in a separate additional thread other than the main application thread. The .NET framework provides you with a class library that allows you to use multithreading and asynchronous programming techniques. In multithreading technique, you can use the thread pool to conquer the new thread, or you can also create it manually. Actually, it depends on the level of control you want to have over the new thread.

Thus, by using multithreading, you can use 2 threads in parallel – the main one, and the newly created one. Both are running in parallel, and this certainly improves the performance and responsiveness of an application.

Basic FCL Namespaces in ASP.NET Programming

We had already introduced our readers to the Framework Class Library in ASP.NET via one of the article in the first week of January. The .NET framework class library is a library of classes, interfaces, and value types that provide access to functionality of the system. All the types in the Framework Class Library are Common Language Specification (CLS) compliant.

The .NET framework contains a lot of namespaces, and each class is arranged in a namespace that best describes its purpose. All the basic FCL classes are located in the root namespace System. The classes, which are provided by any 3rd party developers are recommended to follow the standard NameSpace format of CompanyName.TechnologyName.

Structure of a Namespace:
A basic fully qualified classname example would be System.Collections.ArrayList. The part to the left of the last dot is generally the namespace, while the part to the right of the last for is the classname.

The FCL is based on the common type system. The common type system allows the framework to operate with the multiple languages within a managed runtime.

Global Assembly Cache in ASP.NET

The Global Assembly Cache, popularly known as GAC is a machine-wide .NET assemblies cache for CLR (Common Language Runtime) platform. This justifies their approach of having a specially controlled central repository addresses the shared library concept and helps to avoid the drawbacks. In simpler terms, every computer on which the CLR is installed has a machine-wide code cache – and that is known as Global Assembly Cache (GAC). It enables you to share assemblies across numerous applications for ASP.NET developers.

The GAC is automatically installed with the .NET runtime. It is located in ‘Windows/WinNT’ directory and inherits the directory’s access control list that administrators have used to protect the folder. This is a very unique feature for all the ASP.NET developers. The Global Assembly Cache Tool allow you to view and manipulate the contents of the GAC.

Common Language Specification: ASP.NET Programming Concept

The CLS rules basically define a subset of the Common Type System. The Common Language Specification is the basic set of rules to which any language which is targeting the Common Language Infrastructure (CLI) should confirm in order to interoperate with other CLS-compliant languages. It has been defined as a set of basic language features needed by many applications, which the ASP.NET developers need to develop the applications and services.

When it comes to communication between different objects in .NET languages, those objects must expose all the features that are common to all the languages. The CLS ensures complete interoperability among applications, regardless of the language used to create the application.

It defines a set of Common Type System (CTS) – which in turn describes a set of types that can use different languages for interaction. The Common Language Specification is standardized by ECMA too.

Garbage Collection in .NET

The garbage collection is an inline program running in background to Windows applications. It is basically a mechanism to release the unreferenced objects from the memory. The ASP.NET developers no longer need to worry about the need to manage the life-cycle of the objects they create – the garbage collector will take care of them once the application has finished with them.

When a program creates an Object, the Object takes up the some chunk of the available memory. Later, when the program has no more references to that Object, the Objects’ memory becomes unreachable, but not freed as such. The Garbage collection inspects to see if there are any Objects that are no longer being used by the application. If such objects exist, then the memory used by these Objects can be reclaimed. So, these unreferenced Objects should be removed from memory, and then the other new Objects the developers create can find a place in the program.

In ASP.NET language, there is a provision that we can call Garbage Collector explicitly in the program by calling System.GC.Collect.

Multithreading in ASP.NET

Thread in terms of computer science means a sequence of execution instructions that can run independently, that is a single flow of execution in a process. Multithreading allows multiple processes to execute concurrently within a single program. Multithreading in ASP.NET is very fast and it is able to use the maximum processing power of the computer processor. Every ASP.NET developer should understand the basics of how threads and processes work on the platform they are writing on the go.

If multiple threads exist within a process, typically share the state information of a process, and also share memory and other resources directly. Each thread maintains exception handlers, a scheduling priority, and a set of structures the system uses to save the thread context until it is scheduled.

Concluding..
Using threading in the correct places in the code structure in your applications can greatly improve web server performance, and also provide the Users with a better web experience. So, threading is a very important concept for all the ASP.NET developers, and hope this article helps to build your first application using multithreading concept.

Introduction to .NET Framework Class Library

The .NET framework class library (FCL) provides the core functionality of .NET framework architecture. In standard conditions, the .NET framework classes, interfaces, and the value types that expedite and optimize the development process and provide an access to the system functionality. This is indeed a great support to all the ASP.NET programmers out here, as it has a lot of information to the in-built things that the Microsoft provides to the developers.

The FCL is basically in a tree structure and it is divided into different classified namespaces. The Namespaces in a logical grouping of types and it serves the purpose of identification framework class library. The class library provides the consistent base types that are used across all the .NET enabled languages. The Classes are accessed by the namespaces, which reside within Assemblies. The System Namespace is the root for the types in the .NET framework.

The .NET framework also supports the third-party components that can integrate with the classes in the .NET framework. All the types in the Framework Class Library are Common Language Specification (CLS) compliant. Thus, it allows any CLS compliant programming language to use the types – such as Delphi, C# or VB, and so on.

ASP.NET MVC 4: Bundling & Minification

Any website or web-application is basically built on 2 facets.. server-side programming and Client-side programming. As the Client-side programming/operations increase, the programmers need to make user of more and more JavaScripts to make it more attractive. And as the use of JavaScripts increase, the browsers start responding with typically low response times. To overcome this, we need to combine all JavaScripts files in one. But as far as code maintainability is concerned, this is not the right move. Another way is to combine and minify all the JavaScript files on the program. This is the best possible solution.

With .NET 4.5 and MVC 4, Microsoft has introduced a new feature called Bundling and Minification which bundles the multiple JavaScript and CSS files in one requests and minify their combine effect  by removing white spaces and characters, which are not required. Microsoft introduced a new class called BundleTable which takes care of Bundling and Minification.

The BundleTable class is shipped with two inbuilt Bundles for JavaScript and CSS respectively. However, the ASP.NET programmers can easily create their own custom Bundle as per the requirement. Thus, with .NET 4.5, it is easier to implement Bundling and Minification with very less effort and without major changes. Hope this will be helpful.

Web services in ASP.NET

The web services are the external code write-ups, which are usually used as a smart ways – to be used as injections to the main code of a program. The web service enhancements are the add-ons to the Microsoft .NET Framework which includes a set of classes that implement the additional WS (Web service Specifications). They are basically used to enhance the areas like security, reliable messaging, and sending of the attachments to the various possible places in ASP.NET programming.

They are basic building blocks of the business logic of any program. The business logic components provide the functionality via the Internet using the some of the standard protocols available, for e.g. HTTP.

The web services communicated via different technical messages to the main code of the website. The Web Services Enhancements (WSE) provides extensions to the SOAP protocol and allows the definition of custom security, reliable messaging, policy, etc. The ASP.NET developers can add these capabilities at design time using code or at deployment time through the use of a policy file. Moreover, the web services can convert any application into a web-application, which can publish its function or message to the rest of the world.

The basic web services platform is XML + HTTP.
