## About

<!-- A description of the package and where one can find more documentation -->

Packaged set of simple caching API's derived from those of the same namespace available in .NET Framework since 4.0. This package is intended for use as a bridge when porting .NET Framework applications to .NET.

[Microsoft.Extensions.Caching.Memory](https://www.nuget.org/packages/Microsoft.Extensions.Caching.Memory/)/[IMemoryCache](https://learn.microsoft.com/aspnet/core/performance/caching/memory?view=aspnetcore-7.0) is recommended over `System.Runtime.Caching`/`MemoryCache` because it's better integrated into ASP.NET Core. For example, `IMemoryCache` works natively with ASP.NET Core [dependency injection](https://learn.microsoft.com/aspnet/core/fundamentals/dependency-injection?view=aspnetcore-7.0).

**Use `System.Runtime.Caching`/`MemoryCache` as a compatibility bridge when porting code from .NET 4.x to .NET Core.**

## Key Features
