The Unexpected AI Stack: C# + .NET

This post argues that C# and .NET are underrated foundations for agentic software development, citing build- and run-time type checks, Roslyn analyzers and source generators, EF Core schema checks, and a mature toolchain as guardrails for agent-written code. It highlights Aspire as a programmable runtime orchestration layer with isolated networking for worktrees and a queryable OpenTelemetry sink, and CSharpRepl as a way for agents to connect to a running application and wrap or replace functions at runtime.
