We present a regression test selection technique for C# programs. C# is fairly new and is often used within the Microsoft .Net framework to give programmers a solid base to develop a variety of applications. Regression testing is done after modifying a program. Regression test selection refers to selecting a suitable subset of test cases from the original test suite in order to be rerun. It aims to provide confidence that the modifications are correct and did not affect other unmodified parts of the program. The regression test selection technique presented in this paper accounts for C#.Net specific features. Our technique is based on three phases; the first phase builds an Affected Class Diagram consisting of classes that are affected by the change in the source code. The second phase builds a C# Interclass Graph (CIG) from the affected class diagram based on C# specific features. In this phase, we reduce the number of selected test cases. The third phase involves further reduction and a new metric for assigning weights to test cases for prioritizing the selected test cases. We have empirically validated the proposed technique by using case studies. The empirical results show the usefulness of the proposed regression testing technique for C#.Net programs.

Considering the rapid pace of changes in the software field and the limited courses that a student can take in languages, the question is which languages are crucial for students to learn in an undergraduate IS curriculum. This paper investigates the necessity of teaching C# and .NET in the undergraduate IS curriculum. It explores the pros and cons of .Net versus J2EE for applications development and differences between C#, C++ and Java, and which one may be the best language for teaching first programming course in IS curriculum.

The .NET framework was designed to be the “lingua franca” for Windows development, with the expectation that it will set a new standard for building integrated software for Windows. However, it is inevitable that there is a time lag before .NET is fully adopted and existing applications are recoded. In particular, there is a large body of legacy code that will likely never be rewritten in .NET. To address this situation, Microsoft provides attributes, assembly, and marshaling. At the Numerical Algorithms Group (where I work), our particular interest in using these techniques is to utilize numerical software developed in C from within the .NET environment. Because C# is the premier .NET language, the examples I present here are in C#. While I use an example of data types that are current in the NAG C Library, the techniques I present are general enough for calling unmanaged code written in C from C# directly.

The main focus of this work is on identifying interesting and important aspects of introducing traits to CSharp. We also identify required and optional features for statically typed languages as well as conflict situations. The implementation presented in this paper is a simple prototype (a preprocessor) based on the trait flattening property [9]. It is meant to be a study case for a clean implementation.

This section will introduce you to the Complete Programs tutorial series, the tutorial, creating the project, and adding controls. This project is meant for beginners, so the program will not be as complicated as the others. The program will be similar to the basic calculator in windows.

The C# Complete Program tutorials, similar to the XNA Complete Games, cover programs from start to finish. We start off with a very simple program, and get more advanced as we go. This program is a very simple calculator. We will cover a very abstract way to handle button presses and operations.

Although C# is derived from the C programming language, it has features such as garbage
collection that allow beginners to become proficient in C# more quickly than in C or C++. Similar to Java, it is object-oriented, comes with an extensive class library, and supports exception handling,multiple types of polymorphism, and separation of interfaces from implementations.Those features, combined with its powerful development tools, multi-platform support, and generics, make C# a good choice for many types of software development projects: rapid application development projects, projects implemented by individuals or large or small teams, Internet applications, and projects with strict reliability requirements. Testing frameworks such as NUnit make C# am enable to test-driven development and thus a good language for use with Extreme Programming (XP). Its strong typing helps to prevent many programming errors that are common in weakly typed languages.
