MemoryCache is a caching tool within the .NET Framework that can be used to store data in the application’s memory. To use MemoryCache, it is necessary to make sure that the project has referenced the System.Runtime.Caching namespace.

Install MemoryCache.

Open the Visual Studio project, right-click on the project name, and select “Manage NuGet Packages”.
Search for “System.Runtime.Caching” in NuGet Package Manager and click on Install.
After installation, you can reference the System.Runtime.Caching namespace in your project.

Use MemoryCache:

Instantiate a MemoryCache instance:

MemoryCache cache = MemoryCache.Default;

Store the data in MemoryCache.

cache.Add("key", "value", DateTimeOffset.Now.AddMinutes(10));

Retrieve data from the MemoryCache.

string value = cache.Get("key") as string;

Remove data from the MemoryCache.

cache.Remove("key");

Set the expiration time and priority of cached items.

CacheItemPolicy policy = new CacheItemPolicy();
policy.AbsoluteExpiration = DateTimeOffset.Now.AddMinutes(10);
policy.Priority = CacheItemPriority.Default;
cache.Set("key", "value", policy);

By following the steps above, you can install and use MemoryCache for caching data in your application.
