C# method signature with an optional parameter and a default value, highlighting how the default is baked into the call site.

Using C# Default Parameters Safely

C# default parameters are compiled into callers, so updating a public default may not affect existing consumers. See how optional arguments, named arguments, interfaces, overloads, and API design interact.
