Adapter Design Pattern in C#

The Adapter Design Pattern is a structural pattern that allows incompatible interfaces to work together. It acts as a bridge between two incompatible interfaces, enabling them to collaborate seamlessly without modifying their existing code.The adapter plays the role of converter or translator.

This pattern is particularly useful when integrating new components or systems that have different interfaces from the ones already in use.

To handle the incompatibility, we use different approaches, and based on that, we can classify the Adapter Pattern into 2 parts.

• Object Adapter Pattern
• Class Adapter Pattern

Response Caching in .NET Core with Example

Caching responses is a powerful technique to improve the performance and scalability of web applications. In .NET Core, response caching is a feature that helps store the output of an action method for a specified duration, allowing subsequent requests to retrieve the cached result instead of re-executing the action.

How to Implement Response Caching in .NET Core?

1. Enable Response Caching in Startup.cs

   In the ConfigureServices method of Startup.cs, enable response caching by adding the required services.

       public void ConfigureServices(IServiceCollection services)
   {
       services.AddResponseCaching();
       // Other configurations...
   }
       

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.

IMemoryCache in .NET Core with Example

In .NET Core, managing caching efficiently can significantly enhance the performance of applications. The IMemoryCache interface plays a pivotal role in caching data in memory, providing a simple and effective way to store and retrieve cached data within your applications. This post aims to provide an in-depth understanding of IMemoryCache and its implementation with illustrative examples.

What is IMemoryCache?

IMemoryCache is an interface provided by the .NET Core framework, designed to cache data in memory within an application. It enables developers to temporarily store frequently accessed data, reducing the need to fetch it from the original source repeatedly.

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.
