A screenshot of "dotnet make" in action

A while back, I created "dotnet make" which will invoke your favourite build tool (cake, fake, make, nuke, csproj, fsproj, proj, sln) by convention, regardless of the current working directory in the repository.

I don't think it can be as clear cut as that for us (not everyone uses rider, sometimes linq is fine) so it's really just a prompt to keep an eye out in review

Sometimes. The System.Linq case is actually a good example, as we generally don't want to use it, especially on netfx (as there's normally an uglier but more performant version), so it draws attention of/when it's added

Well, this is insane. I can't access DMs on here unless I "validate my age" with some random company. Who I'm sure won't be a juicy target for a security breach. Or you know, fire up one of dozens of VPNs 🙄

To help reduce the number of UI freezes caused by Resharper, I built an internal tool to measure UI responsiveness.
Here, you can see the improvement between the current 2025.1 version (on the left) and the upcoming 2025.2 version (on the right) with out-of-process enabled.

As I work on Resharper performance, I learn about limitations of .NET (at least, .NET Framework) that I wasn't aware of. Here, I shaved 1 second of CPU time on startup by... removing a call to Array.Empty<T>.

Yep exactly, I just focused on the attributes in this post 🙂

Thanks. Yeah, I mean, it looks similar, thought not quite the same to me. In my case I'm literally not referencing the package myself so I can't even add the conditions AFAICT. At least the linked PRs will address more of the issues.

Yeah, sure, I could drop support for that, but that should be a decision based on my willingness to support it. Not NuGet repeatedly badgering me enough that I get bored, relent, and delete support it out of frustration. Grmbl.

Specifically, it's the netcoreapp2.1 TFM. And yes, that's well out of support. But this is tests for a source generator, which basically supports any TFM, so I want to test the scenarios it could be running in.

In this case, the problem is testing against a bunch of TFMs: github.com/andrewlock/N...

The o11ycast I did with @maddymontaquila.net is up. Expect some profanity and (weird for me) some praise about Aspire :D

We talked about the massive positive impact that Aspire is having on the .NET community accepting OpenTelemetry as the standard.
