I have ported from .NET framework 4.0 to .NET 8.
BinaryFormatter is a security risk, so I changed it to JsonSerializer.

• Changed .NET Framework 4.0 to .NET 8.
• Deprecated BinaryFormatter. Serializable attribute is not required.
• Changed BinaryFormatter to JsonSerializer.
• Changed WinForm to WPF on ExampleGUI.
• Changed nUnit to xUnit Test.
