I'd like to see a Grok Heavy-powered coding agent from @xai that integrates seamlessly with this @code Unified Experience for all Coding Agents
A Unified Experience for all Coding Agents
Agents took over VS Code in 2025. We released agent mode for VS Code, integration for the Copilot coding agent, and the new GitHub Copilot CLI. But Copilot is not the only agent game in town. There…

So more @grokipedia fun: C# history. It added useful info missing on @wikipedia (Ximian then Xamarin entirely absent, white image), until I hit that "C# 13 is latest" (vs C# 14 original). Then I looked at the edits and my mind was fully blown. It wins hands down on accuracy!

Driving the new #dotnet agent framework from TOML configuration is soooo satisfying!
All it takes is one line:
var builder = WebApplication.CreateBuilder(args);
// add config sources
builder.AddAIAgents(); // 👈
Give it a try: www.nuget.org/packages/Dev...

I really really really don't like long strings embedded in my C# code. In agentic AI development (with the new Microsoft Agent Framework), this is even worse since agent instructions/descriptions can be lengthy, and it makes absolutely no sense to build/reload an app just to tweak them

Please @VisualStudio when applying an edit from Copilot, don't re-write (without changes) the sections of the code that don't change. The visual effect (for me) is that I am forced to do the scan for changes as it goes along, and it seems that it could slow down the edit unnecessarily

If I was @Microsoft and owned @GitHub, there's no way I would let this be the status quo of #Windows performance. It's a DISGRACE and makes the whole company look laughable. How can Microsoft's own product be the WORST in his own dev/CI platform?!?!

There’s no place for political violence in civil society. That's an easy one to agree on.
Incitement of violence is also typically a punishable crime in most civil societies. But since what constitutes incitement is less clear, I think it's also easy to agree on courts determining that.
