And now the profiler is deadlocking the GC :^(

When you realize that the C++ exceptions you get while debugging your complicated profiler code come from... the Windows anti-virus

Venez nous retrouver au DevDay 2025... et avec une ristourne de 20% avec ce code devday.be/ticket?disco... ;^) En plus de venir discuter du "moins mauvais" usage des strings avec moi, beaucoup d'autres présentations sont très intéresantes. A très bientôt !

If you want to recompile the .NET 10 RC2 clr to get a solution for VS2026, you should add "18 2026" to that line of runtime\eng\native\gen-buildsys.cmd. Otherwise the build command will fail

The slides and source code for the two #Techorama sessions (including the duet with @kevingosse.net) are available in github.com/chrisnas/Tec...

Whaaaaaaat!!!! My Astronomy Pix of the day app is broken :^(

Too bad it is not version 11111.11

The 3.28 release of the Datadog .NET profiler supports the new allocations sampling of .NET 10 that allows us to provide a much more statistically accurate view of your application memory! github.com/DataDog/dd-t... Thanks Noah Falk for his help on this ~2 years project :^)

I don't understand how people could use GPTs efficiently... I'm looking for implementation details in the .NET runtime for the generation of gcdump and... ChatGPT and Deepseek are just hallucinating even when I'm pointing them to the current CLR main branch :^(

It is not too late to register to @azuredevsummit! Here is a $200 discount code! Discount code = spkrpromo Registration link = azuredevsummit.com/tickets P.S. Meet there to talk about strings in .NET and maybe win a signed copy of the second edition of Pro .NET Memory ;^)

Time to install VS 2026 now :^)

Reminds me great Peter Gabriel french concerts in the 80s petergabriel.bandcamp.com/album/live-a...

Did anyone ever tried to use the Wait Chain Transversal API with critical section? - learn.microsoft.com/en-us/window... implies that it works for critical section but it does not - the wait field always contain 0 for Mutex (I tried infinite and finite wait)

It seems that I mistyped the ZoomIt video recording shortcut...

Starting to look at GPUs...

Time for a break!

So many birds in Tanzania!

C'est vraiment très triste de perdre un tel talent de passeur de connaissances :^( www.pourlascience.fr/sr/regards/r...

See you next year in Krakow!

When you are allocating a little bit more than usual...

One more year as Microsoft MVP Dev :^)

I really enjoyed participating to the last 2codeOrNot2code, so I'm happy to repeat the experience. This time, we will have some fun with functions, unveiling interesting details about what happens when you call them. If you like to understand how things work, don't miss it!

You entered the Mines of Moria... but instead of goblins, you fought off 17 hours of Instagram reels and 3 existential crises. Behold, your final boss: the algorithmic Balrog. 😂

Blogged: Converting a docker-compose file to .NET Aspire andrewlock.net/converting-a... In this post I describe how I converted the deployment method of the mailing-list manager lismonk from a docker-compose.yml file to an Aspire app host project #dotnet #Aspire #csharp

I'm so serious when I'm presenting :^)

🇫🇷 Ma présentation "Comment debugger en production ?" à #DevoxxFR @devoxx.fr est dispo en video www.youtube.com/watch?v=GOmw...

I would not dare debugging Process Explorer!

Tech Talks for Universities are back -- watch today 4/29 at 19:15 CEST aka.ms/TechTalks4Unis

Always measure (but what?) ... preparing my session for @updateconference.bsky.social

Let's meet there to discuss memory and strings!

Blogged: Going beyond singleton, scoped, and transient lifetimes—tenant, pooled, and drifter andrewlock.net/going-beyond... In this post I investigate some 'experimental' dependency injection scopes that provide additional features over Singleton, Scoped, and Transient #dotnet #aspnetcore

Releasing really 157 pages 50-year-old source code on PDF makes sense, I guess? images.gatesnotes.com/12514eb8-7b5...

It seems that VS Code refuses to run on my machine any more...

Join us and ask your .NET memory-related questions!

You can follow folks who are in DevDiv at @microsoft.com The good people are creating frameworks, languages and tools for developers all over the world. go.bsky.app/JuyrK9N

This episode explains how to monitor the startup of a .NET application and get insights about its lock and wait contentions duration. Feel free to install the corresponding "dotnet wait" CLI tool :^)

Take this time machine to see what was our future in 2001 :^)

My newest One Dev Question video just came out; see playlist here: www.youtube.com/playlist?lis...

I need to make some room in my bookshelf so... bye bye Win32 Programmer's Reference

Please Typescript: let me type more!

Thank you @kevingosse.net for showing me the Memory Layout link in Visual Studio: it really helps to get the offset of fields

Back to Matt Pietrek in MSDN Magazine when I need to write a PE format parser in Typescript :^)

Zoomit is now in PowerToys along with other awesome utilities, and is also open source!

An this was a slooow answer...

After writing a profiler in C#, I've now published the first of a series of articles about how use C# to... write a .NET Garbage Collector. #dotnet minidump.net/2025-28-01-w...

www.nuget.org/packages/dot... dotnet-http 1.3 is available with bug fixes (HTTP errors and support more redirect codes) Thanks x.com/tceluiko for the feedbacks :^)

It is really a pleasure to debug an issue with @kevingosse.net: he always has great ideas :^) In my case, our 64 bit stack walker was failing due to a method call that should have been inlined

When Visual Studio refuses to step into/over/out during a debugging session :^(
