Microsoft Agent Framework: Conversations and Threads In an earlier blog post, we took an initial look at the Microsoft Agent Framework in terms of the components that form this new open-source SDK. In this post, we focus on a key component that was mentioned - threads. We see how the Microsoft Agent Framework’s helps you manage conversations using threads. Specifically, the following is covered: foundational concepts creating a conversation without a thread creating a conversation with a thread how to serialise a thread how to deserialise a thread agents and multiple threads threading support and implementation options   Demos and code examples are included.  A video demo is also available. ~ Foundational Concepts Before jumping into some examples, a few important points to note when building agents with the agent framework. State  First, agents are stateless by default.  They don’t maintain sate between interactions. To handle the back and forth between the agent and the human (or another agent

Intercept requests with specific headers - Dev Proxy How to configure Dev Proxy to only intercept requests with specific headers

Testing APIs is noisy when filtering only by URL-irrelevant requests slow you down and hide integration issues. Dev Proxy lets you filter by specific headers and values for focused debugging. Get cleaner logs, diagnose faster, and ship better apps.

HTTP files are awesome for quickly testing APIs. Dev Proxy auto-generates HTTP files from API traffic. This saves time, boosts security, and makes sharing reproducible API scenarios easy for development and collaboration.

I’ve heard good things from folks about the original, not sure how the sequel stacks up, but I guess it’s more of the same.

Un’ecosistema di agenti per Microsoft 365 Copilot | XE - Development User Group [Online Meeting] L’esperienza di Microsoft 365 Copilot si è recentemente arricchita di un vasto ecosistema di agenti: dai declarative agent, realizzati con strumenti come Copilot Studio o Microsoft 365 Agents Toolkit; ai custom engine agent, che possono essere sviluppati con Microsoft 365 Agents SDK, Teams AI Library, Semantic Kernel e Azure AI Foundry. Siete un po’ confusi? Niente paura, nel corso di questa sessione capiremo meglio le differenze e quali strumenti utilizzare in base allo scenario che si vuole implementare.

This Friday I’ll be virtually joining the XeDotNet community for a talk in Italian about agents + Copilot 🚀
We’ll cover:

- How Agent Builder, Copilot Studio, and the Agents SDK fit together
- What this means for devs + organizations

Hardcoded tokens or skipped auth checks cause unreliable authentication simulation, slowing you down. Dev Proxy's AuthPlugin simulates real API key/OAuth2 flows, enforcing auth scenarios. Test auth reliably and launch with confidence.

Another thing which I didn’t know about was that Valve released Half-Life: Uplink for the 25th anniversary to the Steam version of the game. As expected, it’s really well done standalone chapter. Highly recommend playing through it if you’ve not done so.

Shortly after finishing it, I found out about ReShade, a post-processing tool that can applying modern effects, tweaks, and visual filters in real time to any PC game. The results are pretty impressive, simple effects like bloom, make lighting more atmospheric.

a circle with a letter l inside of it on a black background ALT: a circle with a letter l inside of it on a black background

26 yrs after its initial release, I finally finished Half-life.

I’ve lost count how many times I’ve started playing it and then just stopped for no real reason.

The graphics are dated by today’s standards but the story and gameplay is still brilliant.

Run. Think. Shoot. Live.

A scenic view of St. Ives, a coastal town in Cornwall, England. The image shows a sandy beach with gentle waves from the sea, surrounded by a stone pier and breakwater. In the background, there are numerous houses and buildings clustered together on the hillside under a cloudy sky. Greenery is visible in the foreground along with some rooftops.

There's enough horrible things happening in the world.

Please don't have your API return a 200 OK with an error code and add to that list.

Screenshot showing mock data setup for a Microsoft Graph API response. On the left, a JSON file defines a mock GET response for https://graph.microsoft.com/v1.0/me, with user details like name and email. On the right, the terminal displays the mocked response being served from a local proxy.

Testing your app against real-world failures can be a pain. Especially when working with APIs that you don't own like Microsoft Graph. 1/4

Building with OpenAI APIs can get expensive fast-especially when you just need to test parts of your app that don't need real AI replies. 1/4

Closed the week on a high note. @garrytrinder.dev and I have done some really cool stuff for @devproxy.bsky.social. If you use it, be sure you’ve got the Dev Proxy Toolkit VSCode extension so that you can manage configs using natural language. 💪

For debugging code we need symbols/source maps. For debugging APIs we need access to raw requests and responses with their headers. If you’re building an app or an SDK be sure to have a switch to expose this information.
