In C# Csharp. Visual Studio.

Create a class called Employee that includes three pieces of information as either instance variables or auto-implemented properties - first name (type string), last name (type string) and a monthly salary (decimal). Your class should have a constructor that initializes the three values. Provide a property with a get and set accessor for any instance variables. If the monthly salary is negative, the set accessor should leave the instance variable unchanged.

Write the test driver for Employee that demonstrates class Employees capabilities. Create two Employee objects and display each objects yearly salary. Then give each Employee a 10% raise and display each Employees yearly salary again.
