Breaching our Non-Disclosure Agreement at the Microsoft MVP Summit?
Last week, at the #MVPSummit in #Redmond, @roelant.info and I tried to pull information out of true leaders like @markrussinovich.bsky.social, @csharpfritz.com, @davidfowl.com, @maddymontaquila.net, and Amy Boyd

Copilot seems to be half decent at writing PowerShell, which actually makes PowerShell useful for me 😆

Wow, DRM e-books are a total shitshow. Opening a 400 page e-book on a high-end laptop in Adobe Digital Editions is just.... horrible. Flipping through pages is slooow and the book looks like shit.

Interesting reflection from several local coder communities and social media is what this site is shared frequently last couple of days, short term this is likely not changing much, but it could be planting seeds in an way unthinkable just weeks ago.

Hey .NET devs! Are you following @dot.net here on Bluesky already? If not, what are you waiting for?

#Azure naming conventions in some organizations are beginning to look like CSS class names in front-end development. So many characters to denote simple things 😟

Ever wanted to -just- have a #repeating background #job in your APIs? Me too, and I'm somewhat sceptic about introducing another external library. Luckily, .NET #Aspire, Azure #Container #Apps and #Dapr make scheduling tasks a breeze, here is how: hexmaster.nl/posts/schedu...

Of all the code-driven (gherkin is worse) testing styles I see in C#, this is my most hated.

🤮 Relies on hidden implicit class scoped state
😭Mutates it from function to function
🤐Obscures what is actually being verified

All to bury some pseudo-natural-language with underscores.

1/10.

dotnet watch support for Aspire is coming in the next version of the .NET SDK (9.0.200). We rewrote the whole thing 😅.

This should improve scenarios where you need to change individual projects without restarting the entire app host.

Onto our second session of the evening with @florianvandillen.nl from @4dotnet.bsky.social! 🚀 He's sharing his experience on 'Creating a distributed local development environment with #Dapr and .NET #Aspire.' Great energy and discussions as we dive deeper into Dapr!

Finally had time over the holidays to realize a long-standing dream of mine: a hex editor that knows about the PE file and .NET metadata format. You can click any byte and it will show you which data structure it is in the tree. Every byte is covered.

The parser is at github.com/KirillOsenko...

Had a lovely chat with @scott.hanselman.com! On the cozy web vibes of Portland, how anthropology taught me to think, and the need for more complex interfaces for "AI" systems.

Ran into this issue today - DelegatingHandlers in #dotnet use a different scope than the request in which they are running. You can get around it by using IHttpContextAccessor as @andrewlock.bsky.social shows here:

This needs to be better documented.
DI scopes in IHttpClientFactory message handlers don't work like you think they do
In this post I discuss how handler DI scopes work in IHttpClientFactory, and how they're different to the request DI scope.
