What is this?
How to build Redis Cache in ASP.NET Core stores frequently read data closer to the app — memory, Redis, or NCache — so ShopNest.API responds faster.
Why should you care?
Catalog and config endpoints get hammered during sales — caching prevents database meltdown.
See it live — copy this example
Create a Web API (dotnet new webapi), paste the example, run dotnet run, test in Swagger.
if (!_cache.TryGetValue(key, out ProductDto dto))
{
dto = await _svc.GetAsync(id, ct);
_cache.Set(key, dto, TimeSpan.FromMinutes(5));
}
