Perfomance optimalization, debugging and scalability

• The course assumes knowledge and experience with programming in C # at the level of course GOC2124 and GOC2125

• The course is designed for experienced developers who want to move a little further and better understand how memory is handled in .NET, what are the real possibilities of debugging, how code is executed, performance is measured or reflections are used, but also others advanced topics.

• Expert explanation with practical examples, exercises on computers.

• Printed presentations of the subject matter.
