When you are developing an application, you need to know that the development cycle, is the part that will propel you to become, that master programmer, which you are looking to be.
Therefore, you need to embrace, the development cycle of your application, and enjoy every step that is within the development cycle, of your application, so that you may be able, to master a programming language, and never, ever forget that programming language.
It is possible that you forget a programming language, so when develop an application, try to go the long route, never cut any corners and never take the easy route, so that the skills you learn along the process, stick with you forever.
In today's article, we are going to talk about the C# programming language, and all the features that make this programming language great, to develop software and web applications.
Your first program, in any programming language, will be the famous “Hello World” program.
If you are not using that program, to start developing applications, in any programming language you will have a hard time, understanding that programming language, which you would like to learn.
Most developers, if not all, use the famous “Hello World” program, for the purpose of learning, and as their stepping stone, into the programming world and to understand better the language they would like to learn.
In order for you though, to be able to write this simple program in C#, you have to have the visual studio software, installed on your computer.
The visual studio software will give you the environment you need, to start programming in C#.
If you don't have the software, then I suggest you get it installed on your computer, before you are able to write code for the “Hello Word” program, in C#.
Once you have installed, your version of the Visual Studio software, now it's time for you to start programming.
So fire up, your software and start writing code, we do assume here, that you know, how to get around the software though, but if you don't, we suggest, you do some research on this topic, or search through our website, where you can find plenty of information on the subject.
If you can’t find the information you need, simply email us and we’ll get you the information you are looking to find.
Once your Visual Studio is open, chose file, and then new project, of the menu bar, that you will see on the top, left hand corner of the software.
Once you have open a new file, give your project a name and then hit OK.
The new project, will appear on the Solution Explorer, which will allow you to see your files, by providing you with an organized view of your projects and their files, so that you can write and edit your code, as you create it.
Before we do any coding though, let’s talk about the different functionalities and features that C# has and uses as it is compiled, so that you may be able to understand better what is happening in the background.
C# is a managed code, because the code you develop, focuses on the Common Language Run-time (CLR), which means that C# utilizes functionalities that are available through the CLR.
The functionalities of CLR, are made available to your C# code, during run-time, by your compiler and the tools that you use, to write your code in C#, so you can write code that benefits from managed execution environment, when you use C#.
The code that you write in C#, enjoys the benefits of managed execution environment, due to the fact that, you develop with a language compiler that targets the CLR during runtime, this type of code is known as, managed code as we mentioned earlier.
Cross-language exception handling, deployment and version support, a simplified model for integration, profiling services, debugging, enhance security, and cross-language integration, are some of the features, which your C# code benefits from CLR.
Meta data, which describes, the types, members, and references of your code, are emitted, by language compilers and the tools you use, to develop your C# code, in order to allow you, to be able to use the services, provided by CLR during run-time.
In essence, your data in your code, is described by the Meta data, which gives a summary, of the basic information about, your data, so that you may easily work and find data easily.
Meta data are used by the run-time, in order for it, to be able to set run-time context boundaries, generate native code, enforce security, locate and load classes, and lay out instance in memory as well as to resolve method invocations and lay out instances in memory.
Native code by the way, means that the code is computer programming (code) that can only be compiled to run with a particular processor.
The Meta data, has to be found in every loadable common language run-time, which is also portable and executable, in order for you to be able to use, the features provided to managed code.
References to objects, are also managed, by the CLR, and object layout are handled, by the CLR as well.
When objects are no longer needed, they are released, automatically.
Managed data, is the definition of object, which are managed, during the object's lifetime, through Meta data and other features, as explained before.
Some programming errors, that you may overlook, are also handled by the CLR to make your life much better.
Memory leaks is also eliminated, during the Garbage collection process of the CLR.
NET Framework application, which is used by C# to write code, allows you to use managed data, unmanaged data or both; however, the programming language you use, has to be a managed code, otherwise you’ll be forced to use unmanaged data.
Remember that C# is a managed code; therefore, C# is one of those programming languages, where you can use manage or unmanaged data in your .
NET Framework developed application.
You may not always know, or need to know, whether your data is being managed, because programming language compilers, supply their own data types, such as primitive types.
The most basic data types available within any managed code, are primitive types; primitive types include: byte, double, int, long, short, char and float.
Primitive data types, serve as the building blocks for data manipulation in C#, and in any other programming language.
The design of components and applications, whose objects interact across programming languages, are made easy due to the common language run-time.
Alright, I hope you have been keeping up, with the conversation so far, but if you have questions, about what an object is, in terms of CLR is concerned, we can talk about it here for you, to understand, what we are talking about better.
In CLR an object is not similar to that found in, object oriented programming languages.
CLR objects are not as easy to work with as you may think, they are very complex, and you'd have to do a very thorough research for you to be able to fully understand them.
But you can learn about CLR object in no time, because you are on your way to becoming a great programmer.
Objects in CLR, don't have scope; therefore, objects never go out of scope; from the point of construction of the object, to the point that the last reference of that object happens, or is destroyed.
Objects are alive on your code, so think of objects, as the living part of your application development cycle.
In CRL you can change the references, of objects, which is not permitted in other languages, such as C++; for this reason it is said that, CLR really uses, the references of objects.
Objects in CRL, are sometimes known as plain old CLR objects (POCO).
When you start using things like, the repository, object relation mapping (ORM) and dependency injection, then you are using POCO, in a different way.
Object-relational mapping (ORM) makes it possible, for you to manipulate, address and access objects, and not have to worry about considering, how objects, relate to their data sources.
Which means that, you could create ORMs, which pulls data from databases, web services, and applications, to project the POCO or plain old CRL objects.
Regardless of the sources that deliver these objects, and the applications that access them, objects are consistent over time, due to ORM.
In C#, you can use ORM, which provides a clean technique, which supports the communication of incompatible types, in any object-oriented programming language, including C#.
ORM supports the communication of data stored and programming objects; we should also note that the data that is exchanged, between two incompatible states, is taken care of, by your ORM framework.
The CLR that you also use in C#, can help you, simplify the development of your project, integrate your code into various languages, very easy and provide a very secure system, to the application that you develop.
C# targets CLR; therefore, it has access to the entire Framework Class Library (FCL), which is the foundation of the .
FCL is a library of classes, interfaces, and value types, which provides you, with program functionalities.
FCL, is the foundation of the .
NET Framework application, so that the .
NET framework, gives you the ability to build applications, components and controls.
C# follows closely, traditional high-level languages, and you will find important features such as, standard library Boolean conditions, automatic garbage collection, event management, conditional compilation, simplified multi-threading, and integration of your applications to the Windows Operating System.
C# has been evolving since it was first created, and in its evolution, it has acquired, new features, which have made the life, of many programmers, a lot better.
Some of the feature of C#, version 6 in particular are: Exception filters, Support for asynchronous in catch and finally blocks, Support for static "using" statements or Using
You may not understand some of the new features of the C# programming language, you just read; however, we do cover their explanation on other articles, on this website, if you would like to get a better idea, of what it is that we are talking about here.
As you can see though, you should always, continue to do your research, and never stop reading, because the C# programming language, is an ever changing language, that you need to continuously learn.
We didn’t really get into the programming part of the C# language, and we didn’t even tell you the first line of code that you need to write, to start coding in C#.
However, we did talk about a topic that we don’t hear to much about, because new aged programmers don’t believe they need to understand the information you just read.
Trust and believe me though, what you just read will help you in your programming ambitions with C#, so you didn’t waste your time here.
C# programming language, has the ability, to give any developer, a decent standard of life, as far as getting a job is concerned, when you have mastered this programming language.
You can also obtain a great level of life, by being able to create a great application, which could change the life of millions.
But you have to master the C# programming language; not only do you have to master this programming language, but you also have to learn the environment of the language, so that you are able to write your code.
The environment, which you would mostly be using, to write code in C# code would be the .
NET framework, which is a framework that allows developers, to write code in C#, to develop great applications.
