The C# Language

This 3 day course covers C# as a language without targetting any particular application type. A basic knowledge of programming is assumed, though not any particular language. We also offer alternative courses for those interested in the language as well as a particular target such as Windows Forms, ASP.Net or WPF.

The 3 day course costs £1920 in total for up to 6 students, plus VAT and the instructor's reasonable expenses. Each student beyond 6 would cost £20 for the additional course materials.
