These are the topics that are covered in this document: • Eiffel.NET and Envision – I present a tutorial about the integration between Eiffel and the .NET Framework, including step-by- step examples on how to use Envision, how to create Eiffel.NET applications, how to use C# classes in Eiffel code and how to use Eiffel classes in C# code (two-ways integration). • Reflection – I introduce the concept of reflection and how it can be used in the .NET Framework. There are a few code samples that demonstrate the power of reflections – most of them are written in Eiffel. • XML – As a part of this project, I learned how to process XML files using the .NET built-in classes. The .NET class library contains an XML API that makes life for the programmer fairly easy, and I use those classes in the XML Serialization application, which is all written in Eiffel. • XML Serialization – The final deliverable of this project is the XML Serialization application. It is an application that can take any Eiffel object, and store it in an XML file. The application uses both the reflection API and the XML API of the .NET class library.
