@davidfowl @mitchdenny, could help on this?

[davidfowl]

.NET 11, not really important at the moment but run with -d and it should show more info

This issue also happens with the next preview of the .NET 10 SDK: 10.0.200-preview.0.26103.119 #14284. Switching back to the released version of the .NET 10 SDK, aspire new succeeds.

Should be fixed in 13.2

PR: #14285

@JamesNK
this seems still broken with global.json + 10.0.103 in it while having 10.0.200-preview...
I do understand you're saying that it's fixed in the next version.

How do we use the current version though ?

Yes, in 13.2.

You could run aspire update --self and choose daily to get a preview of the next version.
