New in C# 12: Collection expressions

Creating collections becomes simpler in C# 12 using collection expressions. We can also make use of the spread operator .. to copy the values from a collection.

 
 Log(new[] { "one", "two", "three" });
 
 Log(["one", "two", "three"]);
 
 string[] values = ["one", "two", "three"];
 Log([.. values, "four", .. (string[])["five", "six"]]);
 
void Log(string[] values) {}

More info can be found in the documentation.

Feel free to update this developer bit on GitHub, thanks in advance!
