Azure Functions Beyond "Out of the Box" - a Guided Tour of Azure Functions Ext.
summary
Step-by-step guide to building Azure Functions extensions: start with an assembly-level attribute and a Startup class that registers services via the Builder and an ExtensionConfigurationProvider, register converters and binding rules, and implement HTTPClientFactory injection to avoid socket exhaustion. Covers input/value-binder and output/collector patterns, triggers as listener + executor (example: Cosmos DB change feed using a trigger binding provider), DI landing in May 2019, and an open-source RethinkDB extension on GitHub that demonstrates the approach.
