Method I've used is to delete all verified files, then git checkout verified for those received.

Sometimes it's just mean.
Poll results: "Yes, we still use MTP v1" 0% "No, we only use MTP v2" 52% "No, we don't use MTP" 31% "I'm not sure what we use" 17%
We will be removing Microsoft Testing Platform v1 support from the next major release, moving to v2 as the default. We will still support your ability to choose to disable MTP as well. #DotNet #UnitTest
Install DoubleSpace? 🤔😎
💯 Love @carlfranklin.bsky.social weekly Simon update on .NET Rocks, great way to keep up with all new things 😎
Used AVD, then DevBox soon Win365 for six years, as a developer it works really well, and as a consultant is great way to have a dedicated box per customer within their perimiter.
Cool, but as father of a mountainbiker I'm not sure about the $0 😂 it's more a who needs two kidneys anyways situation...
I've created an integration testing framework for Azure Functions (dotnet-isolated) that provides a WebApplicationFactory-like experience. Please give it a try and tell me what you think.

Don't sell yourself short, I'm sure you can say your OSS might get a new feature and you can reevaluate based on what you don't ship 🤔😎
Prospects is they new thing, you sell based on potential followers 🤔😎
Finding joke parity here🤔😎
Unparalleled joke 🤔😎

We just shipped Core Framework v3 4.0.0-pre.33, Analyzers 2.0.0-pre.9, and VS Adapter 4.0.0-pre.3.
This prerelease build adds support for Native AOT, in addition to bug fixes.

We need to show ID in Sweden (or someone with an ID that can vouch for you), but we don't need to register to vote; all 18yo+ citizens are registered/eligible to vote, and their voting card is sent to them, with their current legal name, either electronically or physical depdening on preference.
I wonder if we eventually will just stop and wonder, "Who are we doing this for?"

Good read 👍
BTW , I mentioned of of your older posts on my latest post, time flies 😎
