Sure, here are the steps in more detail:

Create a C# Console Application in Visual Studio
Install the yfinance NuGet package - Open NuGet Package Manager Console and run Install-Package yfinance
Add using yfinance; at the top of your code
Write code like the sample above:

Declare a yfinance.Option object to hold the options data
Call yfinance.Option.Get passing in the ticker symbol ("MSFT")
Print the options data to console

So the full code would be:
```csharp
using System;
using yfinance;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var msftOptions = yfinance.Option.Get("MSFT");
            Console.WriteLine("Options data for MSFT:");
            Console.WriteLine(msftOptions.ToString());
        }
    }
}
```

When you run the console app, it will output the MSFT options data to the console.
