I already have a suggestion open against MSBuild to flag such typos, as they do happen from time to time.

@dotnet/domestic-cat the below just happened. https://github.com/dotnet/core-eng/issues/14015 suggests it's due to build authoring -- two pipelines uploading the same named artifact at the same time. Is that possible here? Which pipeline owns "'BlobArtifacts/dotnet-toolset-internal-6.0.100-ci.zip'"

Same thing happened here:

@dotnet/domestic-cat if this is'nt known to you I can open an issue.

[joeloff]

@danmoseley Can't say I've seen this before. I'd imagine the toolset zip is being produced by the SDK. I'll poke around a bit.

opened #19679 for it
