C# Programming Training – Basics

In this C# programming training the basics of C# and Visual Studio 2017 are presented comprehensively and compactly. An intensive training for software developers in companies who want to program professionally with C# and Visual Studio.

The lecturer Prof. Richard Kaiser has already held well over 100 company seminars on C# and C++. His customers include renowned global corporations and small and medium-sized enterprises. He knows the practical requirements and deals with them in detail both in the basic concepts and in the details.

Prerequisites: Interest in programming. Practical experience with a programming language (e.g. C, C++, C#, Java) is helpful, but not necessary.

Teaching style: Lecture with many examples. A balanced combination of theory and practice.

  • At the beginning of a new topic, an overview of the application possibilities, basic ideas and syntax is described. The concepts and syntax are then illustrated using carefully selected and proven examples.
  • If the participants want to deepen their knowledge independently: The manuscript contains numerous practical exercises.
  • Flexibility: If it turns out during the seminar that the participants lack the basics or that further topics are desired, I can adapt the agenda to the participants’ wishes at any time.

Manuscript: Detailed printed training material (approx. 200 pages) – Complete text, no PowerPoint slides containing only keywords. Therefore the course material can also be used as a reference at work.

Place and time: This seminar is offered as a company seminar (in-house).

Duration: 3-5 days
