How to make simple cricket application in C#

How to make simple cricket application in C# 

Create a class that keeps the updated cricket score in terms of runs, wickets and overs, and has a method that calculates the run-rate and saves it in a separate field. Serialize this class but do not serialize the run-rate field.
Create an application that allows user to display the current score and the run-rate and also allows updating the serializable fields. If running for the first time, when no score is available, the user should be able to input the current score.
Test your application using both types of Formatters, Binary and SOAP for serializing the object. Observe and attach the generated .bin and .xml files
