• Slides (pdf)
• References:
  • A Tour of C# - basic online documentation
  • Code Project - how to do ... in .NET

A - Introduction to the .NET Framework

A.1 - Hello World

a) Implement a "Hello World" application as a Console Application:

• Open VisualStudio.NET.
• Create a new C# console app (.Net Core) project.
• Use the WriteLine method from class Console.

A.2 - Name List

a) Implement an app that manages a list of names.

• Create a new C# console application project.
• Add a new class file (.cs)
• Define the IListaNomes interface, which should include prototypes for:
  • Adding a new name to the list.
  • Returning all names in the list, as a string.
  • Erasing the list's content.
• Create a class that implements IListaNomes and create an instance of it in your console application (use the ArrayList class to store the names).
• Build a console application that uses all features provided by the IListaNomes interface

b) Place breakpoints in each of the class' methods and check that each is called and executed correctly.

B - Introduction to C# G-RPC

B.2 - Chat

Implement a G-RPC based chat application with the following components:

• Server console application, ChatServer ,which registers clients and sends messages;

• Client console application, ChatClient, which sends messages to the server and displays the ongoing conversation.

The suggested client interface:

• Reads the client's nickname

• Reads the port the client will use to receive messages.

• loops reading messages from the console and sending them to the chat until an exit command is input

Notes:

• See the sample G-RPC code.
