Description

Ever since 10.0.3 was installed (as part of the Windows Updates' security updates, see KB5077862), it is not possible to build a Blazor app. The issue also appears when trying to create a new app via the template.

C:\Dev\projets\blazortest3>dotnet new blazor
The template "Blazor Web App" was created successfully.
This template contains technologies from parties other than Microsoft, see https://aka.ms/aspnetcore/10.0-third-party-notices for details.

This is because not all new packages on NuGet have propagated yet. If you try again it will probably work.

I understand this aspect (and it appears 10.0.3 was release as I was writing the issue), but shouldn't the release happen prior to Windows Update pushing the update onto my machine? Right now, I end up with half a day where blazor projects just won't build at all.
