GetOrCreateAsync<TItem>(IMemoryCache, Object, Func<ICacheEntry,Task<TItem>>)	Obtém de forma assíncrona o valor associado a essa chave se ela existir ou gera uma nova entrada usando a chave fornecida e um valor da fábrica especificada se a chave não for encontrada.

Parâmetros de tipo

TItem

O tipo do objeto a ser obtido.

Parâmetros

cache

IMemoryCache

key

Object

A chave da entrada a ser pesquisada ou criada.

factory

Func<ICacheEntry,Task<TItem>>
