When you early commence caption programs in the Visual C# Express IDE (Integrated Development Environment) you will awareness that all but both report you compose must be restrained in a "project" and all in working condition programme you bring into being will be of one or much projects contained in a "solution".

So what is so essential about projects and solutions? Why do you need them? Why can't you a short time ago compose programs?

This article will statement the preceding questions and will speech in the region of how to use projects and solutions to write out larger more than maintainable programs.

In the Beginning

Early programmers wrote tremendously ordinary programs. Often the programs were so uncomplicated they were contained in one report. But, as computers grew in superiority and functionality, programs became so overlarge they had to be break up up into multiple files; and after a while, sets of files, were sorted together by drive into nondisposable libraries. Simple top rank programs (called entry programs) were recurrently transcribed amazingly summarily by incorporating libraries.

Enter Microsoft IDE: Managing the Pieces

Writing programs with beside libraries and submission programs is exceedingly all-powerful and fast, but the computer user is managing lots more files and system modules. Dealing beside all the files in a system of rules as one prolonged list can be confusing, tedious, and imperfection prone; and that is why Microsoft created the belief of "projects" and "solutions" in the Visual C# steps forward environment.

In general, projects are collections of standard files and related paperwork files and resources; solutions are projects classified unneurotic to approach a system of rules.

Canned Projects

To product your vivacity easier, Microsoft put both few "canned" projects to do special tasks. When you firstborn originate a project the IDE offers a selection of canned projects to opt for from. Three of the best critical are the Windows Application project, the Console Application project, and the Class Library jut out over. These are described in subtlety below:

The Windows Application Project sets up a serious windows program. In fact, after you write this project, you can forthwith physical type and run it and it will ordeal an hollow Windows form on your peak. This project is stand alone, in the knack that you do not call for to join it near any new libraries or projects to make up a working program.

The Console Application Project sets up a simple DOS Console caste system. It is slightly corresponding to the Windows Application Project, not including it reads from and writes to a DOS Console. This work is too abide alone, in the connotation that you do not demand to mix up it next to any remaining libraries or projects to construct a practical system of rules.

The Class Library Project is a downright unlike animal from the above two projects. You cannot instigate a engaged system of rules straight from a Class Library Project. Instead, the room contains classes that can be nearly new as an element in a large programme.

Combining Projects into Solutions

In general, you cannot craft a moving system beneath Visual C# Express IDE in need a solution; and that cure will stipulation to contain at lowest one extend beyond.

As an example, I have created a programme to do incised zest subtraction. The system of rules is restrained in a solution named "InterestCalculatorSolution", which in twist contains the Windows Application Project called "InterestCalculator", and a Class Library Project named "FinancialLib".

You can insight a carbon copy of the Interest Calculator Code can be on my .

Create Your Own Solution

After sounding at my example, you will probably deprivation to create your own. It could not be simpler.

1. Start the C# Express postulation.

2. Click on the "File" card portion.

3. Click on "New Project", and superior one of the new labor icons when the "New Project" talking box pops up. I declare a "Windows Application".

4. Give the task a label (text box at the lowermost of the dialog porthole), clink "Ok", and C# Express will generate a new medication and a new labor near the selfsame dub.

You can see icons for both the the mixture and the project in the "Solution Explorer" on the perfectly on the side of the request fanlight.

Now you condition to add some features to your project, but that will be the branch of learning of approaching articles.

Conclusion

Projects and Solutions are a modern visually directed way to set out belief applications and libraries which back you to fabricate resourcefully reorganized computer code from reusable pieces. Fire up your IDE and impart them a try.
