What is caching in ASP.NET MVC and how can I implement it?

Caching in ASP.NET MVC is a technique to store frequently accessed data in memory to improve performance. You can implement it using Output Caching, Data Caching, or Application Caching.

Can you explain the different types of caching available?

Sure! There are three main types: Output Caching, which caches the rendered HTML of a view; Data Caching, which stores data objects; and Application Caching, which is used for application-wide data.

How do I set up Output Caching in my MVC application?

To set up Output Caching, you can use the [OutputCache] attribute on your controller actions. You can specify parameters like duration and location to control caching behavior.

Are there any best practices for using caching?

Yes, some best practices include caching only data that doesn't change frequently, setting appropriate expiration times, and monitoring cache performance.
