JetBrains.Annotations 2025.2.1

JetBrains ReSharper Annotations

ReSharper Annotations help reduce false positive warnings, explicitly declare purity and nullability in your code, deal with implicit usages of types and members, support special semantics of the APIs in ASP.NET and XAML frameworks and otherwise increase the accuracy of the code inspections in JetBrains .NET IDEs.

Available on nuget.org as an ordinary compiled nuget package and a source-code only package.

• `[Conditional("JETBRAINS_ANNOTATIONS")]` attribute was removed from all annotation types, so the assembly reference to `JetBrains.Annotation.dll` is no longer automatically removed by the C# compiler. You can no longer safely use `PrivateAssets="All"` for package reference to `JetBrains.Annotations`. Consider migration to `JetBrains.Annotations.Sources` package if the dependency removal is important for you. • New `JetBrains.Annotations.Sources` package introduced as an alternative way to embed JetBrains.Annotations into your projects without package dependency. • Added `DefaultEqualityUsageAttribute` for equality members usage analysis. • `MustDisposeResourceAttribute` is now allowed on struct types. • Added the ability to specify the description for UsedImplicitlyAttribute (new 'Reason' property). • Added `CqrsCommandAttribute`, `CqrsQueryAttribute`, `CqrsCommandHandlerAttribute`, `CqrsQueryHandlerAttribute` and `CqrsExcludeFromAnalysisAttribute` to support CQRS analyzes of naming and adherence to the pattern. • Package icon update.
