This is a very esay simple application DistributedCaching with Redis For Learn

Defined distributed cache

A distributed cache is a cache shared by multiple app servers, typically maintained as an external service to the app servers that access it. A distributed cache can improve the performance and scalability of an ASP.NET Core app

Used the following nuget package

Microsoft.Extensions.Caching.StackExchangeRedis .

Tech Specification
EFCore7
Redis
Net7

Steps implementation :

1.Install Microsoft.Extensions.Caching.StackExchangeRedis nuget package.

2. configure the Redis service with AddStackExchangeRedisCache(in Program file or Startup)

Example:

services.AddStackExchangeRedisCache(options =>
{ options.Configuration = Configuration.GetConnectionString("RedisConnection");          });

3.Add Connection into appsettings.json

4. Implement all of Methods IDistributedCache For projects(Set, Get, Remove,...)

5. Create a list of CacheKey per Cache

Example:

public static readonly  string PersonCacheKey = "Personall";

6.Use Cache in mvc(in Controller,Action)

Example:

a.Controller

private readonly IDistributedCache _DistributedCache;
public PersonController(IDistributedCache DistributedCache )
 {  _DistributedCache = DistributedCache; }

b.Add Items(Check Exists Cache Based on Key and use SetAsync)

if (!_DistributedCache.TryGetValue(ListCache.PersonCacheKey, out IEnumerable<PersonDto>? PersonDtos))
 {
                var Persons = unitOfWork.Person.GetAll();
                var newperson = _mapper.Map<List<PersonDto>>(Persons);
                await _DistributedCache.SetAsync(ListCache.PersonCacheKey, newperson);
                return View(newperson);
 }
 return View(PersonDtos);
