why the connectionString all empty ?
when i run in my IDE all working properly.
Aspire will not bind it automatically inside K8s or i made a mistake ?
or i wand to bind everting manually in helm values.yaml ?
or have anyother good approach to do that ?

To set expectations, these publishers are in "preview" so they are lots of bugs and its possible you ran into some. That said, I don't know what your issue is or how you deployed. If you can share more of what you did and what the output was then we can figure out where the problems are and file the appropriate issues.

using aspire cli if i generate the helm yaml file they have lot of type miss match issue, like some variable required int for port but aspire cli was passing string value and it is now wiring-up the database and other service automatically, so i use aspire8 to generate the helm yaml file and deploy everting this working fine, yea i know aspire cli is in preview anyway thank for the help and waiting for the stable release to see how it is perform tanks.

aspirate generate --output-format helm

hmm ok let me share all the files.
