After upgrading to Bicep CLI version 0.15.31 (3ba6e06a8d) I got a linter warning in one of my bicep files:
Use a resource reference instead of invoking function “listKeys”. This simplifies the syntax and allows Bicep to better understand your deployment dependency graph.bicep core https://aka.ms/bicep/linter/use-resource-symbol-reference
The offensive line was where I am reading the access key from a log analytics workspace:
listKeys(logAnalyticsWorkspace.id, logAnalyticsWorkspace.apiVersion).primarySharedKey
Unfortunately the URL in the linter message did not resolve to any help page but redirected me to bing instead.
So I tried my best guess as to what the linter tried to tell me and I got lucky:
logAnalyticsWorkspace.listKeys().primarySharedKey
The linter warning disappeared and my deployment continued to work just fine.
This syntax is indeed easier to read. I had no idea, that it was possible to use methods on symbolic references.
