Is it just me, or does GitHub Copilot Agent not have access to .NET 10 SDK yet? It keeps downgrading my net10.0 projects to net9.0 because it can't find the SDK. #dotnetconf

Try do this with C#14 #dotnetconf 2025, you can do it with another dotnet language though. Really? React? F#. Yep. see fable.io for multi runtime language .NET + node + browser + more…

Yeah I'm gonna have to do back and rewatch and give my summary lmao. That's what I get for not factoring in the wild 2 yr old drop kicking me and flipping over me while I'm watching #dotNETConf 😂

Welp my grandson is here and climbing on me like an obstacle course. Will I post something today? That is the big question 😂

@james.newtonking.com I'm watching the #dotnetconf stream and @davidfowl.com just said I would get my most anticipated feature: Persistence for Logs, Metrics and Traces, as soon, as you respond to his message from last night. Please respond asap, I'm waiting for the announcement 😁
November 12, 2025 at 7:49 PM
question for @davidfowl and @damianedwards

Would it be feasible to use the #aspire AppHost to run a distributed app in production. For example in a non-cloud environment? #dotnet #dotnetconf #dotnetconf2025
November 12, 2025 at 7:32 PM
@davidfowl.com the menu icon you just called the “ellipsis menu” •••
is often called “meat balls menu icon” #dotnetconf
Why? Because all menu icons are named after snacks: hamburger, kebab, meat balls, döner, bento…

#dotnetconf how do Aspire commands work when the app is deployed? Would it still allow to execute any executable?
November 12, 2025 at 7:27 PM
Maybe I get to work with .Net more again 😃. Coming full circle after years not touching it.

(Btw, #dotNETconf is currently happening if you're interested)

Lol found a race condition in my spam app, soooo I'm going to retroactively go back and make posts 😂.

The Aspire + azd features (publishing, pipeline creation for Azure DevOps / GitHub), the remote MCP Servers are absolutely freaking amazing.

Trust that I'm about to build things

If you want to build a remote MCP server and already have an ASP.Net Core App running, check out AutoMCP. It automatically converts your endpoints into tools with just one line of code! github.com/wertzui/Auto... #dotnetconf
