Distributed Caching in .NET Core with Example

In .NET Core, managing caching efficiently can significantly enhance the performance of applications.IDistributedCache interface provides a unified approach to caching data in a distributed environment, allowing seamless integration with various caching systems like Redis, SQL Server, or in-memory cache.

What is IDistributedCache?

IDistributedCache is an abstraction in .NET Core that enables applications to interact with distributed cache stores. It offers methods to set, retrieve, and remove cached data in a consistent manner across different cache providers.

What is the difference between IMemoryCache and IDistributedCache?

IMemoryCache and IDistributedCache are both interfaces in ASP.NET Core used for caching data, but they differ in terms of scope and storage.

IMemoryCache

• Scope: Local to the application instance.
• Storage: Caches data in the memory of the local application.
• Usage: Ideal for scenarios where data needs to be cached within the same application instance and doesn't need to be shared across multiple instances or servers.
• Pros: Faster access since it operates within the application's memory.
• Cons: Limited to a single instance and doesn't support sharing data between different instances or servers.
