- Sort data in a loop
- Recognize the classes and methods used in a program

Course Overview:

In this course, you will gain the programming skills that are required for developers to create Windows applications using the Visual C# language. During their five days in the classroom students review the basics of Visual C# program structure, language syntax, and implementation details, and then consolidate their knowledge throughout the week as they build an application that incorporates several features of the .NET Framework 4.7.
This course uses Visual Studio 2017 running on Windows 10.

What You’ll Learn:

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 hierarchyand to extend a .NET Framework class.
Read and write data by using file input/output and streams and serialize/deserialize data in different formats
Create and use an entity data model for accessing a database and use LINQ to querydata
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 C# application
Exam the metadata of types 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
