Microsoft Agent Framework Explained: A .NET Developer’s Architecture Guide

Image
Microsoft Agent Framework brings together agents, workflows, tools, memory, AI models, MCP, multi-agent orchestration, and observability into a single architecture. At first, that can feel overwhelming. There are a lot of concepts to learn: Agents Workflows Sessions Middleware Memory AI models Tool calling MCP Multi-agent systems Observability The individual pieces are easy enough to understand. The difficult part is understanding how they fit together . That is where an architecture diagram helps. Instead of starting with code, let's look at Microsoft Agent Framework from a .NET developer's perspective. The Big Picture Think of an AI agent as an intelligent application built from familiar software engineering components. A typical request might look like this: "Analyze last month's sales, identify the top-performing products, create a PowerPoint summary, and email it to the management team." A traditional application would follow a predefined sequence of API call...

Why Is Your ASP.NET Core API Using So Much Memory? 7 Causes and Fixes

Image
  Why Is Your ASP.NET Core API Using So Much Memory? 7 Causes and Fixes If your ASP.NET Core API is consuming more and more memory, you might immediately suspect a memory leak. Sometimes you're right. But here's the problem: High memory usage doesn't always mean you have a memory leak. An ASP.NET Core API can consume a surprising amount of RAM because of large object allocations, inefficient database queries, unbounded caching, excessive logging, incorrect lifetime management, or simply because the .NET Garbage Collector hasn't returned memory to the operating system yet. I've seen developers try to fix these problems by increasing server RAM. That's usually treating the symptom instead of the cause. In this article, we'll look at 7 common reasons ASP.NET Core APIs use too much memory — and what you can do about them. 1. Loading Too Much Data Into Memory One of the easiest ways to make an API consume memory is to retrieve an enormous amount of data from the ...
