Azure-Samples/cloud-design-patterns ? reverse-engineered prompt

Build me a sample repository for Azure cloud design patterns in C#, with one small working example for each pattern in its own folder. I want clear, runnable demos for things like asynchronous request reply, choreography, claim check, leader election, pipes and filters, priority queue, sharding, static content hosting, and valet key.

Keep it simple and educational, so someone can open each sample and understand the pattern from the code and a short README. Use Azure friendly examples and make the projects feel like real companion code for architecture docs, not a full product. If any pattern needs current Azure guidance or SDK details, look up the latest docs online and use modern approaches.

Also add a top level README that explains what the repo is, what each sample demonstrates, and how to run them. Organize everything cleanly so it is easy to browse and compare the patterns.
