Agentic coding used to come with a tax:

• every token costs money
• your code (and prompts) often leave your machine
• enterprise teams end up stuck between “productivity” and “compliance”

This week, the equation changed.

Ollama added compatibility with Anthropic’s Messages API (v0.14.0+), which means tools like Claude Code can run against local open-source models via localhost.

Translation: you can run “Claude Code-style” agentic workflows on a .NET repo without paying API bills (you still pay in compute, but you get the idea).

Why .NET teams should care

.NET repos are not “toy projects.” They’re:

• monorepos with analyzers, build steps, test containers
• strict CI gates (dotnet test, code style, packaging)
• security-sensitive dependency graphs

Agentic coding only becomes real when the agent can:

1. read the repo,
2. run commands,
3. fix issues iteratively,
4. stay inside guardrails.
