Caching objects on httpcontext asp.net core

问题

I'm trying to migrate from .net framework MVC 5 to .net core 2.0 MVC

good old times I can get or set the cached objects by calling

HttpContext.Current.Application.Lock();
HttpContext.Current.Application["foo"] = bar;
HttpContext.Current.Application.Lock();

but I cant migrated this part of my application to the .net core.

How can I handle this on core 2.0?

回答1:

HttpContext.Current.Application was a feature that was left in to make applications easier to port over from ASP classic. It has been superseded since ASP.NET 1.0 by HttpContext.Current.Cache and since .NET 4.0 by System.Runtime.Caching.

However, all of these caching features are now missing from AspNetCore. There is a lightweight caching option, IMemoryCache that can be used for many scenarios which is similar to HttpContext.Current.Cache. For more scalability, there is also a IDistributedCache.
