Distributed caching with ASP.NET Core and Couchbase

Distributed caching using Couchbase Server can significantly enhance the performance and scalability of ASP.NET Core applications, particularly in server farm or cloud environments. The blog post provides a comprehensive guide on implementing distributed caching through the Couchbase.Extensions.Caching middleware, which is in beta release. It outlines the setup process of a Couchbase Server cluster, including creating a caching bucket and setting up necessary permissions. The integration into an ASP.NET Core project involves minor modifications to the Startup class and the use of the AddDistributedCouchbaseCache extension method. The post also demonstrates caching and retrieving strings and objects using IDistributedCache, with examples of managing cache expiration through DistributedCacheEntryOptions. Additionally, it emphasizes the importance of resource cleanup using the ApplicationStopped event and discusses the security implications of using an outdated Couchbase Server version without password protection.
