Had a great meetup in Aarhus .NET User Group last night, where I got to talk about what’s new for ASP .NET Core 10. 😃 My new workplace was the host which was very convenient and appreciated. 😊

I admire what @captainsafia.com has accomplished in such a short time.
And especially her point that confidence can be built from competence resonates a lot with me.

I attended a talk by Bjarne Stroustrup for the first time today. He told all about the usage of Concepts for generics in C++.
He also had a small jab at C#: "If dynamic reflection is good enough for C#, then why not for C++?" ... "I think we can do better." I loved that comment!

Released version 0.2.4 of ActivityStreams, my implementation of the Activity Streams and Activity Pub vocabulary for .NET.
It fixed a bug reported by @dfyx.social.helios42.de.ap.brid.gy, fixed a misspelling, and added XML Documentation to all types exposed in the API.

@james.montemagno.com do you know if there is an easy way to map multiple different MCP endpoints in a single .NET project, each with their individual tools/methods registered? At work we are building MCPs for helping copilot use our SDKs, but would like to expose seperate tools for each SDK.

I do freelance consultancy. So if any of you have gigs or projects in the area of Blazor, ASP.NET Core, Data Mining, Visualizations, or some combination of these, then I'm currently available for new projects. 😊

I finally found a way to make tests for Blazor JS wrappers in a minimal format. I used to have a lot of boilerplate to control what was evaluated in the browser in each test, but I found out I didn't need that distinguishment, so now it is super simple. 😀

It eases the pain that it is not only me that has been burned by them. 😅
