When IMemoryCache Stops Scaling: Moving to Redis with .NET Aspire

This article from the Building PulseOps series explains why IMemoryCache fails when scaling a .NET API to multiple instances, causing inconsistent cached data. The author demonstrates how to migrate to Redis using IDistributedCache and integrate .NET Aspire to manage Redis as a resource, avoiding manual container setup. The post includes practical steps to reproduce the issue, implement the solution, and verify that multiple API instances share the same cache. It's a technical tutorial focused on distributed caching, .NET Aspire, and real-world architecture evolution.
