When applied to a target attribute, specifies a requirement for any type marked with the target attribute to implement or inherit specific type or types.

Indicates that the value of the marked element could be null sometimes, so the check for null is necessary before its usage

Indicates that the value of the marked type (or its derivatives) cannot be compared using '==' or '!=' operators and Equals() should be used instead. However, using '==' or '!=' for comparison with null is always permitted.

Describes dependency between method input and output

Tells code analysis engine if the parameter is completely handled when the invoked method is on stack. If the parameter is a delegate, indicates that delegate is executed while the method is executed. If the parameter is an enumerable, indicates that it is enumerated while the method is executed

Indicates that the function argument should be string literal and match one of the parameters of the caller function. For example, ReSharper annotates the parameter of ArgumentNullException

Indicates that marked element should be localized or not

Should be used on attributes and causes ReSharper to not mark symbols marked with such attributes as unused (as well as by other usage inspections)

Indicates that the method is contained in a type that implements INotifyPropertyChanged interface and this method is used to notify that some property value changed

Indicates that the value of the marked element could never be null

This attribute is intended to mark publicly available API which should not be removed and so is treated as used

Indicates that a method does not make any observable state changes. The same as System.Diagnostics.Contracts.PureAttribute

Indicates that the marked method builds string by format pattern and (optional) arguments. Parameter, which contains format string, should be given in constructor. The format string should be in Format(IFormatProvider, String, Object)-like form

Indicates that the marked symbol is used implicitly (e.g. via reflection, in external library), so this symbol will not be marked as unused (as well as by other usage inspections)

Specify what is considered used implicitly when marked with MeansImplicitUseAttribute or UsedImplicitlyAttribute
