MemoryCache: obsolete API removed in 3.0

This is a follow up to aspnet/Caching#221. The 3.0 release will remove the obsolete MemoryCacheOptions APIs.

Discussion: dotnet/extensions#1062.

Version introduced

3.0

Old behavior

MemoryCacheOptions.CompactOnMemoryPressure property was available.

New behavior

MemoryCacheOptions.CompactOnMemoryPressure has been removed.

Reason for change

Automatically compacting the cache caused problems. We recommend compacting the cache when needed to avoid unexpected behavior.

Recommended action

To compact, downcast to MemoryCache and call Compact when needed.

Category

  • ASP.NET Core

Affected APIs

MemoryCacheOptions.CompactOnMemoryPressure
