Programming in C# (90 Day) - On Demand (OD20483C)

This training course teaches developers the programming skills that are required for developers to create Windows applications using the Visual C# language. Students review the basics of Visual C# program structure, language syntax, and implementation details, and then consolidate their knowledge as they build an application that incorporates several features of the .NET Framework 4.7.

Microsoft On Demand

Microsoft Official Courses On-Demand (MOC On-Demand) blend video, text, hands-on labs and knowledge checks to help you build your Microsoft technology skills?on your own schedule, at your own pace and in your own place.

  • Microsoft On Demand covers the same objectives as the classroom course by the same name
  • After you activate your course, you have 3 months to complete it. You can work on your course at any time throughout the 3-month period after you activate the course.

Target Audience

This course is intended for experienced developers who already have programming experience in C, C++, JavaScript, Objective-C, Microsoft Visual Basic, or Java and understand the concepts of object-oriented programming.

This course is not designed for students who are new to programming; it is targeted at professional developers with at least one month of experience programming in an object-oriented environment.


  • 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. 


  • Describe the core syntax and features of C#. 
  • Create and call methods, catch and 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, extend a .NET Framework class, and create generic classes and methods. 
  • 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 and update data. 
  • Use the types in the System.Net namespace and WCF Data Services to access and query remote data. 
  • 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. 
  • 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.
