Same error here

[marcpopMSFT]

Same as #29082. @dsplaisted any ideas what could trigger that? It's a benign error as part of the garbage collection but it means workload packs are being left installed.

not repro on today's 7.0.200 preview sdk: 7.0.200-preview.23059.6(runtime- 7.0.0)

I have the same problem when creating a new MAUI Blazor project (SDK 7.02). In Debug it is good, but if I switch to RELEASE: impossible to build.

[dsplaisted]

@tossnet Can you supply a binlog of the failing Release build and the successful Debug build?

[marcpopMSFT]

The original issue was fixed in 2xx. Leaving it open there to follow up on the latest customer report so we eventually close this out in the correct milestone.

[vdanche]

Check on 7.0.103 SDK, Installed android workload without any warning.

Also not repro on VS 17.4 with 7.0.103 inserted when building MAUI Blazor project

Also not repro on 7.0.200 SDK
