问题
I am a little bit lost. I am reading Microsoft documentation for ASP.NET Core chaching using Redis. And the documentation suggests to use Microsoft.Extensions.Cashing.StackExchangeRedis which is an open source third party library.
But I see some other tutorials are using Microsoft.Extensions.Cashing.Redis, which is a more native asp.net core.
And at the end they both use the same interface IDistributedCache
Why I need StackExchangeRedis and what advantages it has over Microsoft.Extensions.Cashing.Redis?
回答1:
A look at the dependency graph for Microsoft.Extensions.Caching.Redis and Microsoft.Extensions.Caching.StackExchangeRedis reveals it.
Microsoft.Extensions.Caching.Redis is based on StackExchange redis 1.x library, whereas Microsoft.Extensions.Caching.StackExchangeRedis is based on 2.x of the same library.
Also Microsoft.Extensions.Caching.Redis doesn't seem to target the 3.1 exteionsn libraries (Microsoft.Extensions.Options/Caching.Abstractions) where the other does.
So for .NET Core 3.x and newer use Microsoft.Extensions.Caching.StackExchangeRedis as the previous one may not be maintained as log as the new one.
