Public Function GetOrCreateAsync(Of TItem) (cache As IMemoryCache, key As Object, factory As Func(Of ICacheEntry, Task(Of TItem))) As Task(Of TItem)Type Parameters
- TItem
The type of the object to get.
Parameters
- cache
- IMemoryCache
The IMemoryCache instance this method extends.
- key
- Object
The key of the entry to look for or create.
- factory
- Func<ICacheEntry,Task<TItem>>
