Just started to document my journey towards a .NET profiler. For me, writing helps a lot to gain a much deeper understanding of what I am just doing. And if I forget about that topic I easily can refresh my knowledge. dev.to/gabbersepp/create-a-n… #dotnet #profiler #cpp #DEVCommunity

I've published the third part of my series of articles about writing a .NET garbage collector in C#. In this one, we add a helper method to inspect the objects in memory, learning about thread modes and the DAC. minidump.net/writing-a-net-g…

My new dotnet-fullgc CLI tool allows you to remotely trigger a garbage collection in .NET application. Type the following to install it: dotnet tool install -g dotnet-fullgc. Read the blog post to learn how to do it yourself! chnasarre.medium.com/trigger…

Trigger your GCs with dotnet-fullgc!

This post explains how I wrote a CLI tool that triggers a GC in any .NET application

Spent hours trying to debug a process in a docker container, struggling with permissions and packages, before remembering that containers on Linux are mostly just a namespace. When you need to run some low-level tools, it might be easier to run them directly from the host.

How is this "peak performance"? Besides 'await', isn't everything else basically syntactic sugar?

Do you know that since early march this year you can now advice #PerfView not to truncate events when dumping them into the event view? You can see the full request sent out with the #HttpClient after tracing the #DumpBuffer event using #dotnet-trace. github.com/microsoft/perfvie…

I did it. My first pull request in the #dotnet project. I feel great, though it was only a small documentation change.

The .NET API ref docs now include links to the source code! We've had many requests for this feature over the years and it's finally here. If the docs don't tell you what you need to know, now you have a direct link to the implementation. Example page: learn.microsoft.com/dotnet/a….
