The AI Gateway in Azure API Management: A Control Plane for Enterprise AI

Wed, 08 Jul 2026 09:00:00 +0530

One control plane for enterprise AI — how APIM’s AI gateway gives security, network, and infrastructure teams governance over models, MCP tools, and agents. The full v2 surface.

Zero-Secrets Architecture on Azure: Managed Identity for AI Agents

Thu, 09 Jul 2026 09:00:00 +0530

The governance case for keyless Azure: why shared keys are a liability, how managed identity plus RBAC fixes it, and how security, network, and platform teams enforce it.

The Auth Chapter Every MCP Tutorial Skips: Real SSO for Microsoft Graph

Wed, 19 Aug 2026 08:00:00 +0530

Production auth for an MCP server on Microsoft Graph: browser SSO with a public client and PKCE, delegated tokens, the On-Behalf-Of exchange, and the engineering that keeps an 85-tool surface safe.

Groundedness Detection vs Groundedness Evaluation: Two Azure Products, One Name

Thu, 06 Aug 2026 08:00:00 +0530

One name, two products, two lifecycle stages. Azure AI Content Safety’s Groundedness detection blocks and corrects ungrounded answers at runtime; the Evaluation SDK’s GroundednessEvaluator scores them offline in CI. Here’s the decision boundary for RAG, the without-Foundry path for each, the honest recall numbers, and the open-source substitutes.

The Production Guardrail Stack: Presidio + Azure Content Safety + NeMo Guardrails Around a MAF Agent

Wed, 05 Aug 2026 08:00:00 +0530

Microsoft ships real code for every guardrail layer, but no sample wires them together around one agent. Here’s the reference stack — Presidio for PII, Content Safety for harm categories, NeMo Guardrails for programmable rails, FIDES for deterministic flow control — where each fits in the MAF middleware pipeline, and the licenses.

Defense-in-Depth for AI Agents on Azure: Prompt Shields, Spotlighting, and the Coverage Gap

Tue, 04 Aug 2026 08:00:00 +0530

Prompt Shields is a real input classifier, but it’s probabilistic — and Spotlighting and Groundedness are model-only, so an agent’s tool calls can pass completely unscanned. Here’s what each defense blocks, where the agent coverage gap is, and how to layer probabilistic filters with deterministic controls.

Cost Control for LLM Apps: Caching, Batching, Model Tiers

Mon, 03 Aug 2026 08:00:00 +0530

The levers that actually move an Azure OpenAI bill — model tier, the four caches, output discipline, batching — in order of impact.

Observability for AI Agents on Azure: OpenTelemetry GenAI to the Agent Dashboard

Mon, 20 Jul 2026 10:00:00 +0530

How to see what an AI agent actually did: the OpenTelemetry GenAI span tree, wired into Azure Monitor, from the agent runtime through the APIM AI gateway and across the MCP boundary — with the copy-paste KQL and the gotchas that will cost you an afternoon.

The Agent Harness

Mon, 20 Jul 2026 09:00:00 +0530

A model can only generate text. The harness is the loop around it that calls tools, manages context, gates actions, and decides when to stop.

Every Evaluator in the Azure AI Evaluation SDK, and When to Use Each

Tue, 14 Jul 2026 09:00:00 +0530

A reference to all 39 evaluators in Azure’s AI Evaluation SDK — quality, RAG, agent, safety, and custom — organized by which ones you can actually import, and which only exist in the cloud catalog.

The OBO Chain Through MCP: Passing User Identity from an Agent to Microsoft Graph

Tue, 14 Jul 2026 09:00:00 +0530

How an AI agent reaches Microsoft Graph as the signed-in user through MCP — why token passthrough fails, and how on-behalf-of, Conditional Access, and RBAC secure the chain.

The Learning Loop Is the Moat: An Architect's Read on Nadella's Reverse Information Paradox

Mon, 13 Jul 2026 11:00:00 +0530

Satya Nadella just named something every architect should pin to the wall. Kenneth Arrow’s old information paradox said a seller can’t prove information’s worth without revealing it: disclose, and you’ve given it away. AI inverts it: now the buyer leaks. To get real value from a model you feed it your proprietary context, and the vendor learns more about you than you learn from it.

Choosing the Right Agent Identity: Managed Identity, Entra Agent ID, OBO, or Service Principal

Fri, 10 Jul 2026 00:00:00 +0530

The first design decision for any Azure AI agent is which identity it uses. A decision matrix across managed identity, Entra Agent ID, on-behalf-of, and service principals.

The Keyless Cookbook: Managed Identity for Every Azure Service Your Agent Touches

Thu, 09 Jul 2026 14:00:00 +0530

The exact RBAC role, disable-local-auth switch, and DefaultAzureCredential snippet for every Azure hop an agent uses — OpenAI, AI Search, Cosmos, SQL, Blob, Key Vault, and more.

Microsoft Foundry's Production-Agent Release: A Solution Architect's Read

Thu, 09 Jul 2026 10:00:00 +0530

Microsoft’s Build 2026 announcement, Frontier models and production agents advancing Microsoft Foundry for the agentic era, reframes Foundry from a model catalog into a place you run production agents. The headline that makes it real: hosted agents in Foundry Agent Service are now generally available, and the catalog spans both OpenAI and Anthropic frontier models (1,900+ on Microsoft Learn, not the “11,000” some coverage repeats).

Zed and DeltaDB: Version Control Between Commits

Wed, 08 Jul 2026 09:00:00 +0530

I used to think the commit was the natural unit of software history. It is clean: a hash, a message, something CI can chew on and a reviewer can revert, cherry-pick, or blame. Then AI coding agents made the gap around the commit impossible to ignore.

Magentic-UI + Fara-7B: A Local-First Computer-Use Agent You Can Actually Run

Thu, 02 Jul 2026 12:00:00 +0530

If you’ve been waiting for a computer-use agent you can run on your own machine (sandboxed, human-in-the-loop, open source), Microsoft’s Magentic-UI is the repo to clone this week. It now leads with MagenticLite (“Big tasks. Small models.”), a redesign from Microsoft Research AI Frontiers that pairs a small-model orchestrator with a dedicated browser-use model and keeps you in control the whole way.

Microsoft Agent Framework Makes Tool and File Access Approval-by-Default

Thu, 02 Jul 2026 10:00:00 +0530

Microsoft Agent Framework’s latest releases, Python 1.10.0 (June 30) and .NET 1.12.0 (July 2), change a security default that’s easy to miss in the changelog: agent tools and file access now require approval unless you opt out. Both land as breaking changes.

AI Security: Prompt Injection, Jailbreaks, and Guardrails

Sun, 24 May 2026 10:00:00 +0530

The OWASP LLM Top 10 exists because shipping an LLM to production without a security model is a new category of risk that the existing web application security playbook doesn’t fully cover. Prompt injection has held the #1 spot on that list since the first version was published, and it’s not there because researchers think it might be a problem someday. It’s been demonstrated against production systems at companies that knew what they were doing.

MCP: What It Is and Why It Changes How You Build AI Tools

Tue, 21 Apr 2026 10:00:00 +0530

Before MCP existed, adding tools to an AI application meant writing the same glue code over and over. You had OpenAI’s function calling syntax. Anthropic had tool use with a slightly different schema. LangChain abstracted over both, but now you depended on LangChain’s versioning decisions. Every new model provider meant rewriting your tool definitions. Every new tool meant re-registering it across every AI integration you maintained.

Building a Multi-Agent E-Commerce Platform: The Complete Guide

Sun, 12 Apr 2026 12:00:00 +0530

Most AI agent tutorials end at “hello world.” You build a single agent with one or two tools, it answers a few questions, and that is it. The gap between that tutorial and a production system with multiple agents, authentication, observability, and a real frontend is enormous.

AI Agents: Concepts and Your First Implementation

Sun, 12 Apr 2026 11:55:00 +0530

Revised with .NET examples — A newer version of this article, covering both Python and .NET, is available as part of the MAF v1: Python and .NET series: MAF v1 — 01-first-agent, MAF v1 — 02-add-tools.

Production Readiness: Auth, RBAC, and Deployment

Sun, 12 Apr 2026 11:25:00 +0530

Revised, split, and expanded — The two halves of this article are now separate chapters in the MAF v1: Python and .NET series: the auth + hardening half is covered by MAF v1 — 20c production hardening (with the password reset, refresh-token rotation, and graceful secret rotation that the original missed), and the deployment half is covered by MAF v1 — 25 deployment (with the .NET twin Dockerfile and a dev.sh that polls instead of sleeping). The architecture below is still the canonical reference for the combined story.

Agent Memory -- Remembering Across Conversations

Sun, 12 Apr 2026 11:20:00 +0530

Revised with .NET examples — A newer version of this article, covering both Python and .NET, is available as part of the MAF v1: Python and .NET series: MAF v1 — 04-sessions, MAF v1 — 05-context-providers.

Evaluating Agent Quality -- Testing What You Cannot Unit Test

Sun, 12 Apr 2026 11:15:00 +0530

Revised with .NET examples — A newer version of this article, covering both Python and .NET, is available as part of the MAF v1: Python and .NET series: MAF v1 — 23-evaluation-framework. The newer version applies three substantive fixes to the framework below — canonical AgentRunResponse extraction (no more hasattr chain), word-boundary alias matching (the original false-positives "profit" against the "price" alias), and a smoke / full tier split for CI vs nightly runs. Read this article for the conceptual ground; read the new one for the production-grade implementation.

Build the smallest useful Microsoft Agent Framework program: one LLM call, one response, and the same shape in Python and .NET.

What Is an AI Agent? (And When Should You Build One)

Tue, 07 Apr 2026 10:00:00 +0530

Every vendor selling software right now claims their product is “agentic.” I’ve seen chatbots with a system prompt called an agent. I’ve seen a scheduled Python script described as autonomous AI. I’ve also shipped actual agents to production, at an insurance company, handling FNOL triage, policy lookup, and claims routing. The gap between what gets marketed as an agent and what you’d actually build in production is wide, and it’s expensive to get wrong.

Dev Tunnels: Test Webhooks and Share Local Apps Without a Deploy

Sat, 04 Apr 2026 10:00:00 +0530

If you read the Cloudflare Tunnel post, you know the problem: localhost does not accept webhooks, OAuth providers reject http://localhost as a redirect URI, and showing a client a work-in-progress means a deploy. Cloudflare Tunnel solves it, but it wants a Cloudflare account and domain setup.

Why I Switched from npm to pnpm (And Why You Should Too)

Fri, 03 Apr 2026 10:00:00 +0530

If you write JavaScript or TypeScript professionally, you’ve used npm. It ships with Node.js, it’s everywhere, and for years it was the only game in town. But after running npm on real-world projects (enterprise monorepos, Next.js apps, Angular dashboards, CI pipelines that bill by the minute), I can tell you: npm is holding you back.

Building Dictum — a macOS Dictation App with Tauri 2 (Rust + React) & Azure OpenAI

Sat, 21 Mar 2026 10:00:00 +0530

macOS has had built-in dictation since Monterey. It is fine: press and hold a key, speak, done. But it requires Apple’s servers (unless you download the enhanced on-device model), only works in some apps, and you have zero control over punctuation, formatting, or hotkeys.

Azure App Registration: A Complete Guide from Zero to Working App

Sat, 10 Jan 2026 10:00:00 +0530

Every Microsoft integration I have shipped starts at the same gate. Call the Graph API, wire up SharePoint, add “Sign in with Microsoft” to an app, and none of it works until you have an App Registration. Get it wrong and nothing downstream authenticates, which is why this is the one setup step I slow down for instead of clicking through.

Cloudflare Tunnel: Expose localhost for Webhooks and OAuth

Sat, 03 Jan 2026 10:00:00 +0530

Expose localhost with a stable custom subdomain using Cloudflare Tunnel — a free ngrok alternative that works behind NAT and corporate firewalls, with no session limits.

Adding .NET Aspire to an Existing Clean Architecture Project

Sat, 20 Dec 2025 10:00:00 +0530

The exact steps to add Aspire to a running .NET + Angular + PostgreSQL app: two projects, one line in Program.cs, and a project reference.

Building Production-Ready Microservices with .NET Aspire: A Complete E-Commerce Demo

Sat, 06 Dec 2025 10:00:00 +0530

A production-quality .NET Aspire demo — five microservices, PostgreSQL, Redis, and RabbitMQ, all orchestrated from a single C# AppHost file.

Microsoft Ignite 2025: Microsoft Foundry - The Unified Enterprise AI Platform

Sat, 22 Nov 2025 12:00:00 +0530

I was at Microsoft Ignite for the Foundry announcements, and the framing runs ahead of the substance. Microsoft rebranded most of its Azure AI stack as Microsoft Foundry: one PaaS spanning models, agents, tools, knowledge, and governance. Underneath the launch-day gloss, three things actually matter to anyone shipping enterprise agents.

Build Custom MCP Catalogs with Docker: Enterprise Control for AI Tooling

Fri, 24 Oct 2025 09:00:00 +0530

Docker shipped a set of tools that let a platform team decide exactly which Model Context Protocol servers developers can run: a catalog format, an open-source Gateway, and a Toolkit built into Docker Desktop. The official catalog carries 220+ containerized MCP servers, and you can fork it, trim it, or build a private catalog that points at images in your own registry.

.NET Architecture at Scale: Visual Guide to Modern Design Patterns

Sat, 05 Jul 2025 12:00:00 +0530

.NET Architecture at Scale: Visual Guide to Modern Design Patterns
#

I keep a page like this open in a browser tab. When a team asks which pattern fits a new service, I would rather point at a decision tree and a comparison table than argue it from memory for the third time that month. So I wrote the reference I wanted: the 16 patterns I actually reach for in .NET systems, each with its diagram, a code sketch, and the trade-off it forces on you.

Streamlining AI Development with LiteLLM Proxy: A Comprehensive Guide

Sun, 25 May 2025 09:00:00 +0530

At some point I had three side projects each talking to a different LLM provider, with API keys pasted into three .env files and three slightly different client wrappers. Swapping GPT-4o for Claude in any of them meant editing code. That is a silly amount of friction for what is, underneath, the same chat-completion call, so I put a LiteLLM proxy in front of everything and never went back.

Elevating Code Quality with Custom GitHub Copilot Instructions

Sat, 24 May 2025 09:00:00 +0530

The first time I let Copilot loose on one of my Angular repos, it wrote a perfectly reasonable component for 2021: constructor injection, class properties for state, NgModule imports. We were on Angular 19 with signals and standalone components.

Building a Comprehensive RAG System: A Deep Dive Into Knowledge Architecture

Thu, 24 Apr 2025 10:00:00 +0530

TL;DR: This guide walks you through building a production-ready RAG system using FastAPI, ChromaDB, MinIO, and OpenAI. Learn document chunking, vector embeddings, hybrid search, and real-world deployment strategies.

Introduction
#

As a .NET developer watching the AI space move fast, I found myself both excited and skeptical. When tools like Claude.ai and ChatGPT started offering out-of-the-box RAG solutions, I wanted to build my own system with full control over the implementation.

Stretch Tracker: Advanced Technical Architecture and Implementation

Sun, 20 Apr 2025 08:00:00 +0530

The Birth of the Stretch Tracker: A Developer’s Story
#

As developers, we often find ourselves deeply immersed in our work, sitting for hours on end in front of our screens without even realizing how much time has passed. I was no different. During a particularly intensive project, I noticed the toll these long coding sessions were taking on my physical health - back pain, stiff neck, and decreased productivity became unwelcome companions in my daily routine.

Simplify Your Workflow: How to Build Custom Commands with the .NET CLI

Tue, 14 Jan 2025 09:00:00 +0530

Our support team used to open the Azure portal every time someone needed a user’s group memberships. Click through Azure AD, find the user, expand groups, copy the list, paste it into a ticket. A dozen times a day. It was slow, and it needed portal access we would rather not hand out widely.

Deploying Ollama with Open WebUI Locally: A Step-by-Step Guide

Sat, 11 Jan 2025 09:00:00 +0530

I run LLMs on my own machine for two reasons: my prompts never leave my hardware, and I can experiment all day without watching an API meter. The setup used to be the hard part. Wrangling Python environments, CUDA drivers, and model weights by hand was enough friction that most people quit before the first token.

Simplify Git Workflows Across Multiple Repositories with Git Submodules and Meta-Repositories

Fri, 10 Jan 2025 09:00:00 +0530

Six repositories, one system, too many clone commands
#

On a typical microservices project I have five or six repositories open at once: a couple of APIs, a frontend, shared infrastructure scripts, sometimes a docs repo. Onboarding a new developer meant a wiki page full of clone commands, and “which commit of the API works with this frontend?” was answered by asking whoever was online.

Simplifying Database Queries with AI & SQL Automation

Mon, 06 Jan 2025 09:00:00 +0530

Business users kept asking my team for one-off data pulls: how many orders above $150 in December, which products are low on stock, that sort of thing. Every request meant a developer dropping their work to write a throwaway SQL query. So I built a REST API that does the translation instead. It feeds the database schema to an LLM, gets back a SQL query, runs it, and returns JSON. One codebase, four interchangeable providers (OpenAI, Azure OpenAI, Claude, and Gemini), switched by a single environment variable.

Efficient File Management on Azure Blob Storage: CRUD Operations and Upload Strategies

Sun, 29 Dec 2024 09:00:00 +0530

The short version
#

Four ways to get a file into Azure Blob Storage from a .NET and Angular app, and when each one earns its keep:

Implementing SharePoint File CRUD Operations using Microsoft Graph API

Tue, 24 Dec 2024 09:00:00 +0530

Introduction
#

Storing files in SharePoint from a .NET service sounds like it should be a solved problem, and it is, as long as you make one decision early: delegated or application permissions. That single choice changes who shows up as “Created by” on every file and whether your service needs a signed-in user at all. Get it wrong and you rebuild the auth layer later.

Building an AI-Driven Chat Application with .NET, Azure OpenAI, and Angular

Sat, 07 Dec 2024 09:00:00 +0530

Introduction
#

I built this chat app to answer a narrow question: how little infrastructure do you actually need to stream tokens from Azure OpenAI into a browser? Less than most tutorials assume. There is no SignalR here and no WebSocket hub.

Best Practices for Creating and Using DTOs in the API
