Pull Request Overview
This PR adds a new WithoutMessage method to FluentAssertions that validates an exception message does NOT match a given wildcard pattern, providing the inverse functionality to the existing WithMessage method.
- Adds
WithoutMessagemethod to both synchronous and asynchronous exception assertions - Refactors internal message assertion logic to use a generic action delegate approach
- Updates error messages from "exception message" to "the exception message" for consistency

As missing handling of AssertionScopes also exists in main it's not blocking for merging this PR.

This PR adds a new
WithoutMessagemethod to FluentAssertions for exception testing that validates an exception message does NOT match a given wildcard pattern.The implementation adds both synchronous and asynchronous variants of
WithoutMessagethat mirror the existingWithMessagefunctionality, but useNotMatchEquivalentOfinstead ofMatchEquivalentOffor the inverse assertion.The code also refactors the internal message assertion logic to be more generic by accepting an action delegate that defines how to assert against the message, allowing both positive and negative message matching to share the same underlying infrastructure.
Minor improvements include changing the error message identifier from "exception message" to "the exception message" for better readability.
Closes #3093
