Caching platforms

.NET 5 supports multiple caching platforms. A few of the commonly used cache platforms are as follows:

• In-memory cache: In this, the cache data is stored inside the process memory. For example, if the application is hosted on IIS, the in-memory cache will consume memory from w3wp.exe.
• Distributed cache: Data is stored across multiple servers. The data stores that can be integrated with .NET 5 applications are SQL Server, Redis, and NCache.

In-memory cache

To configure memory caching, after creating a new ASP.NET Core 5 MVC/Web API application, or for an existing ASP.NET Core 5 MVC/Web API application, the following code changes are required:

1. Add services.AddMemoryCache() to the ConfigureServices method of Startup.cs. This extension method is part of Microsoft.Extensions.DependencyInjection (install this NuGet package if it's missing) and maps the IMemoryCache interface to the MemoryCache class.
2. The MemoryCache class is a built...
