- Updated xunit.v3 from 3.2.2 to 4.0.0 in test project - Updated xunit.v3.extensibility.core from 3.2.2 to 4.0.0 in src project - Suppressed NU1608 warning for AutoFixture.AutoNSubstitute dependency constraint (AutoFixture.AutoNSubstitute 4.18.1 hasn't officially declared NSubstitute 6.x support but they are compatible in practice) - Updated README.md to reflect new xunit version in installation example - Applied editor config formatting updates
Extends the built-in specimen coverage of FixtureFactory with three generators following the existing [AutoRegister] + ISpecimenBuilder pattern, so they are discovered automatically with no user action. - TimeOnlyGenerator: mirrors DateOnlyGenerator via TimeOnly.FromDateTime, closing the gap where DateOnly was supported but its sibling was not - UriGenerator: produces readable absolute URIs on the reserved example.org domain instead of AutoFixture's noisy defaults, improving assertion failure messages - TimeProviderGenerator: returns a fixed provider reporting a stable fixture-generated UTC instant with LocalTimeZone set to UTC, making time-dependent code deterministic and enabling [Frozen] TimeProvider to share one instant between the SUT and the assertions No new package dependencies were taken; the fixed provider is internal rather than depending on Microsoft.Extensions.TimeProvider.Testing, to keep the core package dependency-light. Also fixes a copy-paste error in the DateOnlyGenerator XML summary, which incorrectly read "has not been canceled". Adds 5 tests to CustomizationsTests, including coverage of frozen TimeProvider reuse and Uri uniqueness.
Documents AutoRegisterAttribute (contract, discovery, example) and ImmutableObjectCustomization (rationale, supported types), and fixes a typo in StringExtensions. Narrows NU1608 from a solution-wide NoWarn to a scoped PackageReference on NSubstitute, with a documented removal trigger, so future constraint violations are not hidden.
Leads with a 30-second before/after example and demotes the rationale below the usage content, so a new user sees the payoff first. Adds a cheat sheet, common recipes, a built-in specimen support table, a troubleshooting/FAQ section and a version compatibility table, and rewrites the table of contents to match.
…behaviour Add docs/working-with.md, a long-form companion to the README covering the four data attributes, [Frozen] semantics (including exact-type promotion and the deliberate non-promotion across interfaces), [AutoRegister] discovery and its constraints, the FixtureFactory customization pipeline, and the helper extensions.

Summary
Package upgrades
xunit.v3.extensibility.core3.2.2 → 4.0.0 (andxunit.v34.0.0 in the test project)NSubstitute5.3.0 → 6.2.0AwesomeAssertions9.4.0 → 9.6.0Microsoft.NET.Test.Sdk18.6.0 → 18.9.0Microsoft.SourceLink.GitHub10.0.300 → 10.0.400Meziantou.Analyzer3.0.104 → 3.0.177,SonarAnalyzer.CSharp10.27 → 10.32NU1608
AutoFixture.AutoNSubstitute4.18.1 declaresNSubstitute (>= 2.0.3 && < 6.0.0), soresolving NSubstitute 6.2.0 raises NU1608. The used API surface is compatible, so the
warning is suppressed — but scoped to the resolved
NSubstitutereference ratherthan suppressed globally, with an inline comment recording the condition for removal
(an AutoFixture release declaring NSubstitute 6 support). The build is warning-free.
New specimen generators
Three types that previously either failed to generate or produced unusable values:
TimeOnlyGenerator— derives from a generatedDateTimeUriGenerator— deterministic, readable absolute URIs with sanitised segmentsTimeProviderGenerator— a fixed provider with a stableGetUtcNow()and UTClocal zone, making
[Frozen] TimeProvidera practical way to pin the clockCovered by new tests in
CustomizationsTests.Documentation
leads, followed by a cheat sheet, common recipes, a built-in specimen support
table, and a troubleshooting FAQ. The rationale sections were demoted rather than
removed.
docs/working-with.md: long-form guide covering the four data attributes,[Frozen]semantics (including exact-type promotion and the deliberatenon-promotion across interfaces),
