--getProperty:GeneratedContainerConfiguration no longer returns a value in SDK 9.0.102 when running dotnet publish

[sgtwilko]

Describe the bug

when running dotnet publish /t:PublishContainer --getProperty:GeneratedContainerConfiguration in SDK version 9.0.102 we no longer get the Generated Container Confioguration.

To Reproduce

This is a project that I created via Visual Studio, first by creating a new ".NET Aspire Empty App", then by adding a new "ASP.NET Core Web API"

They were created with the defaults.

The main branch on this Repo has the issue, the branch than pins the SDK to 9.0.100 works:
https://github.com/sgtwilko/AspirePublishFail

Navigate to the API folder then run dotnet publish /t:PublishContainer --getProperty:GeneratedContainerConfiguration.
The expected result is that this should create the container and output the GeneratedContainerConfiguration JSON.

e.g.,

On the latest 9.0.102 the command finishes running without erroring, but fails return the `GeneratedContainerConfiguration` JSON.

This will cause azd up, azd deploy to fail.

If you use SDK 9.0.100 (see the sdk9.0.100 branch) this works and returns the JSON that is expected from GeneratedContainerConfiguration.
I haven't tried 9.0.101, so not sure it was introduced in 101, or 102.

Exceptions (if any)

I see your repro project has RuntimeIdentifiers instead of RuntimeIdentifier, so I suspect you are hitting #46053 - there's a bug in 9.0.102 that is making the container tooling always publish for multiple RuntimeIdentifiers if RuntimeIdentifiers is present, regardless of if RuntimeIdentifier is set. When publishing multiple containers, the GeneratedContainerConfiguration Property is no longer present - instead the GeneratedContainers Item is provided that contains much of the same information.

For now, I would suggest pinning to 9.0.101 at the latest - we expect 9.0.103 in February to fix this regression.

Hi @baronfel

Thanks that makes sense.
I did spot the multiple containers being generated, and thought that might have something to do with it.
The repo project is just using the VS defaults for Aspire, so had thought it to be fairly safe.

Just as an FYI, #46053 is causing Azure/azure-dev#4713 as azd is no longer able to publish due to the missing GeneratedContainerConfiguration

Looks like baronfel fixed this already, so this can be closed as completed?

[baronfel]

yep!
