CallerArgumentExpression and extension methods don’t mix

This post is for the C# developers out there and takes a look at the interesting conjunction of [CallerArgumentExpression] and static extension methods – a mix that at first seems too convenient to pass up.

A quick recap: [CallerArgumentExpression] landed as part of the C# 10.0 language update and helps to reduce the (often brittle!) boilerplate involved in, among other uses, creating useful error messages capturing the names of variables or the text of expressions. You tag an optional string method parameter with [CallerArgumentExpression("argName")] where argName is the name of the method argument you want stringified, and the compiler does the rest.

We are proud to present the latest addition to our open source portfolio, the library! We’ve extracted a number of encoding- and emoji-related namespaces and functions from a few of our projects going back many years and split them off to create an open source library that can be used to aid in the safe processing and manipulation of (possibly) internationalized strings and non-ASCII characters (and then some). is designed from the ground-up as a modern approach to text processing and text encoding, with only support for the most popular Unicode encodings: UTF-8, UTF-16, and UTF-32. Additionally, is designed to complement .NET’s existing (albeit extremely limited) Unicode support, instead of supplanting it, which primarily translates to embracing rather than shunning the System.String type wherever possible. Unlike many other text-processing libraries, does not want you to stop using the system types for string representation and to switch over to custom datatypes 😁.
