This project uses ASP.NET Core's IDistributedCache abstraction with Redis to share cached data between application instances. If you only need a cache inside one application process, my in-memory caching project is a better starting point.

I've also blogged this with a full explanation of how this is achieved.

main targets .NET 10 LTS. The unsupported .NET 5 version remains available on the dotnet5 branch for historical reference.

1. User requests a user object.
2. App server checks if we already have a user in the cache and return the object if present.
3. App server makes a HTTP call to retrieve the list of users.
4. Users service returns the users list to the app server.
5. App server sends the users list to the distributed (Redis) cache.
6. App server gets the cached version until it expires (TTL).
7. User gets the cached user object.

Requirements:

• .NET 10 SDK
• Docker with Docker Compose

Start Redis:

docker compose up -d

Run the application:

dotnet run --project DistributedCache/DistributedCache.csproj

Build and test the solution:

dotnet test
