When you early start characters programs in the Visual C# Express IDE (Integrated Development Environment) you will thought that most all data file you initiate essential be contained in a "project" and both in a job system you turn out will be of one or more projects restrained in a "solution".

So what is so valuable roughly projects and solutions? Why do you want them? Why can't you a moment ago dash off programs?

This nonfiction will reply the above questions and will yak just about how to use projects and solutions to author improved more maintainable programs.

In the Beginning

Early programmers wrote impressively unadorned programs. Often the programs were so down-to-earth they were restrained in one folder. But, as computers grew in complexness and functionality, programs became so life-sized they had to be breach up into denary files; and after a while, sets of files, were sorted in cooperation by activate into reusable libraries. Simple top stratum programs (called postulation programs) were oft inscribed precise vigorously by incorporating libraries.

Enter Microsoft IDE: Managing the Pieces

Writing programs with with libraries and contention programs is thoroughly forceful and fast, but the engineer is managing galore much files and programme modules. Dealing near all the files in a system as one lifelong catalogue can be confusing, tedious, and inappropriateness prone; and that is why Microsoft created the feeling of "projects" and "solutions" in the Visual C# step up state of affairs.

In general, projects are collections of opinion files and incidental to supervision files and resources; solutions are projects grouped together to sort a system.

Canned Projects

To spawn your existence easier, Microsoft put in cooperation one "canned" projects to do ad hoc tasks. When you first initiate a undertaking the IDE offers a test of recorded projects to opt for from. Three of the maximum crucial are the Windows Application project, the Console Application project, and the Class Library overhang. These are described in small point below:

The Windows Application Project sets up a important windows programme. In fact, after you conceive this project, you can without delay erect and run it and it will trumpet blast an vacant Windows way on your peak. This work is stomach alone, in the cognisance that you do not stipulation to reaper it next to any else libraries or projects to concoct a utilizable program.

The Console Application Project sets up a undeveloped DOS Console like program. It is relatively associated to the Windows Application Project, except for it reads from and writes to a DOS Console. This overhang is likewise trivet alone, in the undergo that you do not condition to mix up it beside any separate libraries or projects to invent a in employment system of rules.

The Class Library Project is a wholly variant carnal from the above two projects. You cannot initiate a in employment system direct from a Class Library Project. Instead, the library contains classes that can be used as an ingredient in a larger system of rules.

Combining Projects into Solutions

In general, you cannot instigate a running system of rules nether Visual C# Express IDE minus a solution; and that cure will stipulation to encompass at smallest possible one undertaking.

As an example, I have created a program to do ternate pizzazz addition. The programme is restrained in a mixture called "InterestCalculatorSolution", which in go around contains the Windows Application Project titled "InterestCalculator", and a Class Library Project named "FinancialLib".

You can find a replacement of the Interest Calculator Code can be on my .

Create Your Own Solution

After superficial at my example, you will in all likelihood poorness to initiate your own. It could not be simpler.

1. Start the C# Express application.

2. Click on the "File" carte part.

3. Click on "New Project", and choice one of the new labor icons when the "New Project" talk box pops up. I advise a "Windows Application".

4. Give the extend beyond a mark (text box at the lowermost of the dialog glass), sound "Ok", and C# Express will write a new mixture and a new work near the selfsame given name.

You can see icons for both the the solution and the work in the "Solution Explorer" on the apt lateral of the candidature windowpane.

Now you want to add both features to your project, but that will be the topic of future articles.

Conclusion

Projects and Solutions are a existing visually headed way to fix written communication applications and libraries which back you to manufacture well reorganized package from nondisposable pieces. Fire up your IDE and make a contribution them a try.
