Programming in C# | Creating Applications in C# and .Net Core (20483)

Course Objectives

Working in a dynamic, intensive coding environment you will learn to:

• Describe the core syntax and features of Visual C#.
• Create methods, handle exceptions, and describe the monitoring requirements of large-scale applications.
• Implement the basic structure and essential elements of a typical desktop application.
• Create classes, define and implement interfaces, and create and use generic collections.
• Use inheritance to create a class hierarchy and to extend a .NET Framework class.
• Read and write data by using file input/output and streams, and serialize and deserialize data in different formats.
• Create and use an entity data model for accessing a database and use LINQ to query data.
• Access and query remote data by using the types in the System.Net namespace and WCF Data Services.
• Build a graphical user interface by using XAML.
• Improve the throughput and response time of applications by using tasks and asynchronous operations.
• Integrate unmanaged libraries and dynamic components into a Visual C# application.
• Examine the metadata of types by using reflection, create and use custom attributes, generate code at runtime, and manage assembly versions.
• Encrypt and decrypt data by using symmetric and asymmetric encryption.

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional application development, secure coding, secure software development, hacking, database security, bug hunting and other related topics that may be blended with this course for a track that best suits your needs. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.

Course Prerequisites

Developers attending this course should already have gained some limited experience using C# to complete basic programming tasks. More specifically, students should have hands-on experience using C# that demonstrates their understanding of the following:

• How to name, declare, initialize and assign values to variables within an application.
• How to use: arithmetic operators to perform arithmetic calculations involving one or more variables; relational operators to test the relationship between two variables or expressions; logical operators to combine expressions that contain relational operators.
• How to create the code syntax for simple programming statements using C# language keywords and recognize syntax errors using the Visual Studio IDE.
• How to create a simple branching structure using an IF statement.
• How to create a simple looping structure using a For statement to iterate through a data array.
• How to use the Visual Studio IDE to locate simple logic errors.
• How to create a Function that accepts arguments (parameters and returns a value of a specified type).
• How to design and build a simple user interface using standard controls from the Visual Studio toolbox.
• How to connect to a SQL Server database and the basics of how to retrieve and store data.
• How to sort data in a loop.
• How to recognize the classes and methods used in a program.
