Debugging and Diagnostics

When you are working in the development of your application, you will normally encounter unexpected problems due to logical or runtime errors, even if the application is being tested or in production and you want to monitor the health of an application or to gather the extra information that you need to identify errors or bugs. To take care of such problems or identify and fix such errors or monitor an application’s health, C# and Microsoft Visual Studio helps us out in this case to provide classes and tools for debugging and diagnostics.

Serialization and Deserialization

When communicating with remote applications, you will often exchange data with other applications.

Fundamentals of C

To get more out of this chapter, grab a pencil and paper, note down each point, and write code snippet in Microsoft Visual Studio 2012 or above. At the end of this chapter, you can practice all concepts by: reviewing summary, completing code challenges, and solving multiple choice questions.

Working with Cryptography

Security is an important part to cover when developing your application. You need to take care about data privacy, user authenticity, data travel security and that data is not be compromised.

Deep Dive into LINQ

LINQ is a feature of C# introduced in .NET 3.5. It lets you work with different types of data and provides an easy and powerful way to write and maintain queries.

File I/O Operations

Interacting with files is a common task when developing an application. Sometimes you need to store some kind of information into files and store that information in a different format (i.e., binary or text), or you need to send or access some kind of data over the network. In these scenarios, a .NET framework provides classes to deal with them.

Implementing Delegates & Events

In any modern language, event-driven development is used to structure a program around various events. These events perform a certain functionality when a certain condition satisfies, for example, close the application when a user clicks on the “Exit” button. Or shut down the system when the heat Temperature rises, etc.

The C# Programmer’s Study Guide (MCSD)

Class Abstract classes cannot be instantiated. It is used as base class, where it provides common members to all its derived classes. It is either overridden partially or not at all. It is also used to declare abstract methods (method without definition) that when it inherits, it must be overridden by its derived classes.

Types in C

C# is a strongly-typed language. It says, data must have a type that defines its nature and behavior. Type helps to manipulate data in a much managed way.
