Are plugins REALLY any different than adding extension methods?
The amount of code is definitely similar! However, we don't need a central point in the code to go update every time we want to extend or change functionality.

Use Redis With HybridCache to Cache Your EF Core Data!
In earlier videos in the series, we saw how we could convert our Entity Framework Core data access from IMemoryCache to HybridCache!
But... there was one big problem:
It was still just a memory cache behind the scenes!

If we have all of our code cloned, many tools can look across folders. But having these capabilities all from the web with cloud agents... absolute dream.
