Properties

	Name	Description
	BuiltInTypeKind	Gets the built-in type kind for this TypeUsage.(Overrides MetadataItem::BuiltInTypeKind.)
	Documentation	Gets or sets the documentation associated with this type.(Inherited from MetadataItem.)

Methods

	Name	Description
	CreateBinaryTypeUsage(PrimitiveType^, Boolean)	Creates a TypeUsage object to describe a binary type by using the specified facet values.
	CreateBinaryTypeUsage(PrimitiveType^, Boolean, Int32)	Creates a TypeUsage object to describe a binary type by using the specified facet values.
	CreateDateTimeOffsetTypeUsage(PrimitiveType^, Nullable<Byte>)	Creates a T:System.Data.Metadata.Edm.DateTimeOffsetTypeUsage object of the type that the parameters describe.
	CreateDateTimeTypeUsage(PrimitiveType^, Nullable<Byte>)	Creates a T:System.Data.Metadata.Edm.DateTimeTypeUsage object of the type that the parameters describe.
	CreateDecimalTypeUsage(PrimitiveType^)	Creates a TypeUsage object to describe a decimal type with unbounded precision and scale facet values.
	CreateDecimalTypeUsage(PrimitiveType^, Byte, Byte)	Creates a TypeUsage object to describe a decimal type by using the specified facet values.
	CreateDefaultTypeUsage(EdmType^)	Creates a TypeUsage object with the specified conceptual model type.
	CreateStringTypeUsage(PrimitiveType^, Boolean, Boolean)	Creates a TypeUsage object to describe a string type by using the specified facet values and unbounded MaxLength.
	CreateStringTypeUsage(PrimitiveType^, Boolean, Boolean, Int32)	Creates a TypeUsage object to describe a string type by using the specified facet values.
	CreateTimeTypeUsage(PrimitiveType^, Nullable<Byte>)	Creates a T:System.Data.Metadata.Edm.TimeTypeUsage object of the type that the parameters describe.
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	IsSubtypeOf(TypeUsage^)	Checks whether this TypeUsage is a subtype of the specified TypeUsage.
	ToString()	Returns the full name of the type described by this TypeUsage.(Overrides Object::ToString().)

Extension Methods

	Name	Description
	Constant(Object^)	Overloaded. Creates a new DbConstantExpression of the specified primitive type with the given constant value. (Defined by DbExpressionBuilder.)
	New(array<DbExpression^>^)	Overloaded. Creates a new DbNewInstanceExpression. If the type argument is a collection type, the arguments specify the elements of the collection. Otherwise the arguments are used as property or column values in the new instance.(Defined by DbExpressionBuilder.)
	New(IEnumerable<DbExpression^>^)	Overloaded. Creates a new DbNewInstanceExpression. If the type argument is a collection type, the arguments specify the elements of the collection. Otherwise the arguments are used as property or column values in the new instance. (Defined by DbExpressionBuilder.)
	NewEmptyCollection()	Creates a new DbNewInstanceExpression that constructs an empty collection of the specified collection type. (Defined by DbExpressionBuilder.)
	Null()	Creates a new DbNullExpression, which represents a typed null value. (Defined by DbExpressionBuilder.)
	Parameter(String^)	Creates a new DbParameterReferenceExpression that references a parameter with the specified name and type. (Defined by DbExpressionBuilder.)
	Variable(String^)	Creates a new DbVariableReferenceExpression that references a variable with the specified name and type.(Defined by DbExpressionBuilder.)
