# Azure Functions
## Patterns
### Isolated Worker Model (.NET)
Modern .NET execution model with process isolation
### Node.js v4 Programming Model
Modern code-centric approach for TypeScript/JavaScript
### Python v2 Programming Model
Decorator-based approach for Python functions
## Anti-Patterns
### ❌ Blocking Async Calls
### ❌ New HttpClient Per Request
### ❌ In-Process Model for New Projects
## ⚠️ Sharp Edges
| Issue | Severity | Solution |
|-------|----------|----------|
| Issue | high | ## Use async pattern with Durable Functions |
| Issue | high | ## Use IHttpClientFactory (Recommended) |
| Issue | high | ## Always use async/await |
| Issue | medium | ## Configure maximum timeout (Consumption) |
| Issue | high | ## Use isolated worker for new projects |
| Issue | medium | ## Configure Application Insights properly |
| Issue | medium | ## Check extension bundle (most common) |
| Issue | medium | ## Add warmup trigger to initialize your code |
