C# Error
CS8401 – To use ‘@$’ instead of ‘$@’ for an interpolated verbatim string, please use language version ‘{0}’ or greater.
Reason for the Error & Solution
To use @$ instead of $@ for an interpolated verbatim string, please use language version ‘8.0’ or greater.
In older versions before C# 8.0, verbatim interpolated strings were only allowed using $@. Starting with C# 8.0, you can use $@ or @$.
To correct this error
Either replace @$ with $@, or upgrade to C# 8.0 or later.
