class	CanBeNullAttribute
	Indicates that the value of the marked element could be null sometimes, so checking for null is required before its usage.
class	CannotApplyEqualityOperatorAttribute

	Indicates how method, constructor invocation, or property access over collection type affects the contents of the collection. When applied to a return value of a method indicates if the returned collection is created exclusively for the caller (CollectionAccessType.UpdatedContent) or can be read/updated from outside (CollectionAccessType.Read | CollectionAccessType.UpdatedContent) Use CollectionAccessType to specify the access type.
class	ContractAnnotationAttribute
	Describes dependency between method input and output.

	Tells the 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 can only be invoked during method execution (the delegate can be invoked zero or multiple times, but not stored to some field and invoked later, when the containing method is no longer on the execution stack). If the parameter is an enumerable, indicates that it is enumerated while the method is executed. If RequireAwait is true, the attribute will only takes effect if the method invocation is located under the 'await' expression.
class	InvokerParameterNameAttribute
	Indicates that the function argument should be a string literal and match one of the parameters of the caller function. This annotation is used for paramerers like 'string paramName' parameter of the System.ArgumentNullException constuctor.
class	ItemCanBeNullAttribute
	Can be applied to symbols of types derived from IEnumerable as well as to symbols of Task and Lazy classes to indicate that the value of a collection item, of the Task.Result property or of the Lazy.Value property can be null.
class	ItemNotNullAttribute
	Can be applied to symbols of types derived from IEnumerable as well as to symbols of Task and Lazy classes to indicate that the value of a collection item, of the Task.Result property or of the Lazy.Value property can never be null.
class	LanguageInjectionAttribute
	Indicates that the marked parameter, field, or property is accepting a string literal containing code fragment in a language specified by the InjectedLanguage.
class	LinqTunnelAttribute
	Indicates that the method is a pure LINQ method, with postponed enumeration (like Enumerable.Select, .Where). This annotation allows inference of [InstantHandle] annotation for parameters of delegate type by analyzing LINQ method chains.
class	LocalizationRequiredAttribute
	Indicates whether the marked element should be localized.
class	MacroAttribute
	Allows specifying a macro for a parameter of a source template.
class	MeansImplicitUseAttribute
	Can be applied to attributes, type parameters, and parameters of a type assignable from System.Type . When applied to an attribute, the decorated attribute behaves the same as UsedImplicitlyAttribute. When applied to a type parameter or to a parameter of type System.Type, indicates that the corresponding type is used implicitly.
class	MustUseReturnValueAttribute
	Indicates that the return value of the method invocation must be used.
class	NoEnumerationAttribute
	Indicates that IEnumerable passed as a parameter is not enumerated. Use this annotation to suppress the 'Possible multiple enumeration of IEnumerable' inspection.
class	NonNegativeValueAttribute
	Indicates that the integral value never falls below zero.
class	NoReorderAttribute
	Prevents the Member Reordering feature from tossing members of the marked class.
class	NotifyPropertyChangedInvocatorAttribute
	Indicates that the method is contained in a type that implements System.ComponentModel.INotifyPropertyChanged interface and this method is used to notify that some property value changed.
class	NotNullAttribute
	Indicates that the value of the marked element can never be null.
class	PathReferenceAttribute
	Indicates that a parameter is a path to a file or a folder within a web project. Path can be relative or absolute, starting from web root (~).
class	ProvidesContextAttribute
	Indicates the type member or parameter of some type, that should be used instead of all other ways to get the value of that type. This annotation is useful when you have some "context" value evaluated and stored somewhere, meaning that all other ways to get this value must be consolidated with existing one.
class	PublicAPIAttribute
	This attribute is intended to mark publicly available API, which should not be removed and so is treated as used.
class	PureAttribute
	Indicates that a method does not make any observable state changes. The same as System.Diagnostics.Contracts.PureAttribute.
class	RazorDirectiveAttribute
class	RazorHelperCommonAttribute
class	RazorImportNamespaceAttribute
class	RazorInjectionAttribute
class	RazorLayoutAttribute
class	RazorPageBaseTypeAttribute
class	RazorSectionAttribute
	Razor attribute. Indicates that the marked parameter or method is a Razor section. Use this attribute for custom wrappers similar to System.Web.WebPages.WebPageBase.RenderSection(String).
class	RazorWriteLiteralMethodAttribute
class	RazorWriteMethodAttribute
class	RazorWriteMethodParameterAttribute
class	RegexPatternAttribute
	Indicates that the marked parameter, field, or property is a regular expression pattern.
class	RequireStaticDelegateAttribute
	This annotation allows to enforce allocation-less usage patterns of delegates for performance-critical APIs. When this annotation is applied to the parameter of delegate type, IDE checks the input argument of this parameter:
class	RouteParameterConstraintAttribute
	Indicates that the marked type is custom route parameter constraint, which is registered in application's Startup with name ConstraintName
class	RouteTemplateAttribute
	Indicates that the marked parameter, field, or property is a route template.
class	SourceTemplateAttribute
	An extension method marked with this attribute is processed by code completion as a 'Source Template'. When the extension method is completed over some expression, its source code is automatically expanded like a template at call site.
class	StringFormatMethodAttribute
	Indicates that the marked method builds string by the format pattern and (optional) arguments. The parameter, which contains the format string, should be given in the constructor. The format string should be in string.Format(IFormatProvider,string,object[])-like form.
class	StructuredMessageTemplateAttribute
	Indicates that the marked parameter is a message template where placeholders are to be replaced by the following arguments in the order in which they appear
class	TerminatesProgramAttribute
	Indicates that the marked method unconditionally terminates control flow execution. For example, it could unconditionally throw exception.
class	UriStringAttribute
	Indicates that the marked parameter, field, or property is an URI string.
class	UsedImplicitlyAttribute
	Indicates that the marked symbol is used implicitly (e.g. via reflection, in external library), so this symbol will be ignored by usage-checking inspections. You can use ImplicitUseKindFlags and ImplicitUseTargetFlags to configure how this attribute is applied.
class	ValueProviderAttribute
	Use this annotation to specify a type that contains static or const fields with values for the annotated property/field/parameter. The specified type will be used to improve completion suggestions.
class	ValueRangeAttribute
	Indicates that the integral value falls into the specified interval. It's allowed to specify multiple non-intersecting intervals. Values of interval boundaries are inclusive.
class	XamlItemBindingOfItemsControlAttribute
	XAML attribute. Indicates the property of some BindingBase-derived type, that is used to bind some item of ItemsControl-derived type. This annotation will enable the DataContext type resolve for XAML bindings for such properties.
class	XamlItemsControlAttribute
	XAML attribute. Indicates the type that has ItemsSource property and should be treated as ItemsControl-derived type, to enable inner items DataContext type resolve.
class	XamlItemStyleOfItemsControlAttribute
	XAML attribute. Indicates the property of some Style-derived type, that is used to style items of ItemsControl-derived type. This annotation will enable the DataContext type resolve for XAML bindings for such properties.
class	XamlOneWayBindingModeByDefaultAttribute
	XAML attribute. Indicates that DependencyProperty has OneWay binding mode by default.
class	XamlTwoWayBindingModeByDefaultAttribute
	XAML attribute. Indicates that DependencyProperty has TwoWay binding mode by default.
