Constant Interpolated String

• From C# 10, const strings may be initialized using string interpolation if all the placeholders are themselves constant strings.
• String interpolation can create more readable constant strings in your application.
• The placeholder expressions can't be numeric constants because those constants are converted to strings at run time.

const string Language = "C#";
const string Platform = ".NET";
const string Version = "10.0";
const string FullProductName = $"{Platform} - Language: {Language} Version: {Version}";
Console.WriteLine(FullProductName);
