Run Python in-process from .NET with CSnakes
A quick tip for embedding Python directly into a .NET app with CSnakes when you want a small slice of the Python ecosystem without a separate API service.
Csharp
Separate prompts from authorization
Do not let prompt instructions decide what data or actions a user is allowed to access.
Start independent tasks before awaiting them
Create unrelated asynchronous operations first, then await them together.
Use approval for side effects, not for every tool call
Reserve human approval for actions where a wrong call would actually matter.
Use file-based C# apps for small repo utilities
Use a single C# file when a repo utility is useful but a full project would be ceremony.
Use HybridCache when cache stampedes matter
Use HybridCache for expensive shared lookups where many callers can miss at once.
Use managed identity before connection strings
Prefer Azure-managed identities over long-lived secrets in deployed applications.
Use OpenTelemetry before you need production debugging
Add traces, metrics, and logs while the system is still easy to reason about.
Use ProblemDetails as your API error contract
Return one predictable error shape instead of inventing a new JSON format for every failure.
