1.33.1

• UnnecessaryEnumerableMaterialization: No longer flags ToHashSet() as an unnecessary materialization since it performs deduplication
• LinqTraversalBeforeFilter: No longer flags Reverse(), Take(), TakeLast(), or TakeWhile() before Where() since reordering would change semantics

1.33.0

• TimeSpanConstructedWithTicks: Detect new TimeSpan(value) with a single argument, which creates ticks (100ns) instead of seconds
• UnboundedStackalloc: No longer triggers when the stackalloc is inside a ternary expression with a heap allocation fallback
• StructWithoutElementaryMethodsOverridden: Turned off by default
• DivideIntegerByInteger: Set to Info by default
• HttpClientInstantiatedDirectly: No longer triggers in test classes (xUnit, NUnit, MSTest)
• DateTimeNow: Set to Info by default
• SwitchIsMissingDefaultLabel: Set to Info by default
• SwitchDoesNotHandleAllEnumOptions: Set to Info by default
• AttributeMustSpecifyAttributeUsage: No longer triggers on abstract attribute base classes
• DisposeAsyncDisposable: No longer triggers when the containing method is not async
• TestMethodWithoutTestAttribute: No longer flags property accessors as potential test methods

1.32.0

• RedisResponseNotHandled: Detect when Redis response objects are discarded without checking for errors
• ActivityWasNotStopped: Fixed a false positive when the activity is directly returned from a method
• DisposableFieldIsNotDisposed: Disposable fields that belong to a type now trigger when they are not included in any reachable disposal path
• DisposeAsyncDisposable: Detects asynchronously disposable concrete types even when the local is declared as an interface or base type
• SwitchDoesNotHandleAllEnumOptions: Now analyzes switch expressions as well as switch statements
• SwitchIsMissingDefaultLabel: Now analyzes switch expressions and requires a discard arm as the default case
• ParameterAssignedInConstructor: Now also detects suspicious assignments from this.-qualified fields and properties
• TestMethodWithoutPublicModifier: internal methods with xUnit no longer trigger this
• TestMethodWithoutPublicModifier: Parameterized test attributes such as NUnit.TestCase and MSTest.DataTestMethod are now recognized
• TestMethodWithoutTestAttribute: NUnit classes can now be recognized through sibling [Test] methods even when [TestFixture] is omitted
• RecursiveOperatorOverload: Fixed a false positive when a different overload is selected

1.31.1

• MultipleFromBodyParameters: Support Minimal Web APIs (lambda expressions)

1.31.0

• LoggerMessageAttribute: This analyzer suggests converting regular logging calls to the source-generated logging pattern.

1.30.0

• StringConcatenatedInLoop: Now also catches interpolated strings
• StringPlaceholdersInWrongOrder: Retains existing whitespace when applying the code fix
• LinqTraversalBeforeFilter: Implemented a code fix to swap the traversal and filter calls
• ComparingStringsWithoutStringComparison: Supports null-conditional access, e.g. myString?.ToLower() == otherString?.ToLower()
• UnnecessaryToStringOnSpan: A Span<char> or ReadOnlySpan<char> was converted to a string using .ToString() when an overload accepting a (ReadOnly)Span<char> exists. Use that overload instead to avoid unnecessary allocations.

1.29.0

• Fixed an ignored test MultipleOrderByCalls_MultipleOrderByChained
• ActivityWasNotStopped: An Activity was started but is not being stopped or disposed
• FlagsEnumValuesAreNotPowersOfTwo: Trigger on enums that use binary expressions in member values
• ValueTaskAwaitedMultipleTimes: A ValueTask was awaited multiple times, which leads to undefined behavior

1.28.0

• ImmutableCollectionCreatedIncorrectly: ImmutableArray is being created using 'new' instead of the Create method

1.27.1

• TestMethodWithoutTestAttribute: Don't trigger when NUnit.TestCase or NUnit.TestCaseSource is present on a method

1.27.0

• ElementaryMethodsOfTypeInCollectionNotOverridden: Don't exclude all System assembly types, exclude only structs
