Constructors

	Name	Description
	Lazy<T, TMetadata>(TMetadata)	Initializes a new instance of the Lazy<T, TMetadata> class with the specified metadata.
	Lazy<T, TMetadata>(TMetadata, Boolean)	Initializes a new instance of the Lazy<T, TMetadata> class with the specified metadata and thread safety value.
	Lazy<T, TMetadata>(TMetadata, LazyThreadSafetyMode)	Initializes a new instance of the Lazy<T, TMetadata> class with the specified metadata and thread synchronization mode.
	Lazy<T, TMetadata>(Func<T>, TMetadata)	Initializes a new instance of the Lazy<T, TMetadata> class with the specified metadata that uses the specified function to get the referenced object.
	Lazy<T, TMetadata>(Func<T>, TMetadata, Boolean)	Initializes a new instance of the Lazy<T, TMetadata> class with the specified metadata and thread safety value that uses the specified function to get the referenced object.
	Lazy<T, TMetadata>(Func<T>, TMetadata, LazyThreadSafetyMode)	Initializes a new instance of the Lazy<T, TMetadata> class with the specified metadata and thread synchronization mode that uses the specified function to get the referenced object.

Properties

	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Creates and returns a string representation of the Lazy<T>.Value property for this instance.(Inherited from Lazy<T>.)
