    Inherits ServiceConstructor

public abstract class ServiceConstructor<TService> : ServiceConstructor

Type Parameters

• TService
  A Type that determines the type of service object that instances of this class can create.

The ServiceConstructor<TService> type exposes the following members.

Constructors

	Name	Description
	ServiceConstructor<TService>	Initializes a new instance of the ServiceConstructor<TService> class.

Properties

	Name	Description
	DatabaseSchemaProvider	Gets or sets the current database schema provider. (Inherited from ServiceConstructor.)

Methods

	Name	Description
	Clone	Duplicates the current instance.
	ConstructService	Called by a DatabaseSchemaProvider to create an instance of the specified TService type.
	ConstructServiceImplementation	Called by the ConstructService method to return a new instance of the specified TService Type.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

A DatabaseSchemaProvider uses this ServiceConstructor<TService> class when it executes its GetService<TService> and GetServiceConstructor<TServiceConstructor> methods.

Notes to Inheritors

You can add properties to classes that are derived from the ServiceConstructor<TService> that can then be applied to the created instances by the ConstructServiceImplementation method.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
