bool	true if a service of type T is registered; otherwise, false.

Type Parameters

T	The type of the service to check.

Get<T>()

public T Get<T>() where T : class

Returns

Type	Description
T	The registered service instance.

Type Parameters

InvalidOperationException	Thrown when no service of type T is registered.

Register<T>(T)

Registers a service instance for the specified type.

Declaration

public void Register<T>(T service) where T : class

Parameters

Type	Name	Description
T	service	The service instance to register. Must not be null.

Type Parameters
