Definition

Overloads

GetOrCreateAsync<TItem>(IMemoryCache, Object, Func<ICacheEntry,Task<TItem>>)

Asynchronously gets the value associated with this key if it exists, or generates a new entry using the provided key and a value from the given factory if the key is not found.

GetOrCreateAsync<TItem>(IMemoryCache, Object, Func<ICacheEntry,Task<TItem>>, MemoryCacheEntryOptions)

Asynchronously gets the value associated with this key if it exists, or generates a new entry using the provided key and a value from the given factory if the key is not found.

Type Parameters

TItem

The type of the object to get.

Parameters

cache
IMemoryCache

The IMemoryCache instance this method extends.

key
Object
