In my project some developer added method that has optional parameter in parameters list:
public static string GeneratetPopupCall(string pageName,bool withEscapeChar = false)
I know that optional parameters are part of C# 4.0.
But our project is targeted to .net 3.5. (C# 3.0)
My question is:
Why it compiles if 3.5 doesn’t support optional parameters? Why that is no compilation or syntax error?
You are using the 4.0 compiler, targeted at the 3.5 framework.
This compiles to a runtime 2.0 compatible IL.
