Use when representing optional values explicitly — Maybe<T> as a null-safe container, Maybe.From()/FromTry() for creation, HasValue/HasNoValue, Map/Bind chaining, TapNone for None-side effects, Match for consumption, and ToMaybeResult() to bridge into the Result pattern.
Use when handling operation outcomes without exceptions — Result and Result<T> for success/failure, railway-oriented chaining with Then/ThenAsync/Ensure, Match for consumption, and Result.And/Or for combining multiple results.
Use when composing business validation logic — define rules as classes, Func fields, or inline lambdas; combine with .And()/.Or()/.Linear()/.Next(); evaluate with RuleEngine.Evaluate(); branch with RuleEngine.If().
Use when modeling partial success — These<TError, TValue> holds Left (error only), Right (value only), or Both (error + value), enabling scenarios where a result can partially succeed while carrying warnings. Use FromResult to bridge from Result<T>, ToResult/ToResultLenient to bridge back, and Partition to split collections.
Use when you need testable time — IDateTimeProvider wraps clock access so production code uses DateTimeProvider while tests use the built-in FakeDateTimeProvider to freeze/advance/set the clock; also provides .ToDateOnly() and .ToTimeOnly() DateTime extension methods.
Use when adding cross-cutting pipeline behaviors to CQRS handlers — ValidationBehavior (CSharpEssentials.Validation, throws EnhancedValidationException), LoggingBehavior (ILoggableRequest), ExceptionHandlingBehavior (auto-converts exceptions to Result.Failure for Result-returning handlers), CachingBehavior (ICacheable with IDistributedCache), and TransactionScopeBehavior (ITransactionalRequest).

Directory.Packages.props. Never set Version= directly in a .csproj.<PackageReference Include="Foo" /> (no version) in projects; version is resolved centrally.<IsPackable>true</IsPackable> is the default (set in Directory.Build.props); only override to false for test/example projects.GeneratePackageOnBuild is false — packing is done explicitly via dotnet pack or the publish script.<IncludeSymbols>true</IncludeSymbols> and <SymbolPackageFormat>snupkg</SymbolPackageFormat> on all packable projects.
