I really enjoyed chatting with Jamie about Minimal APIs, OpenAPI, and MCP!
(𝟭/𝟰) Latest episode of The Modern .NET Show dropped, and it's a goodie.
@mikekistler.bsky.social from Microsoft breaks down OpenAPI and Model Context Protocol. Both are transforming how we build APIs and AI-powered tools.
Some genuinely mind-blowing moments in this one 👇

If anyone knows how to automatically close the terminal instance that runs the "postCreateCommand" in a #devcontainer opened in #vscode, please let me know! I am constantly rebuilding my devcontainer to get to a clean state, and having to close that window every time is annoying!

Python is completely broken for me. I can't install packages, even when I have (reluctantly) created a virtual environment. pip install fails with "error: externally-managed-environment". So frustrating.

But I just finished co-presenting the OpenAPI session at #dotnetconf and it always feels good to pause and reflect on the progress that's been made.
