If I had multiple applications in my dapr.yaml with the same appID, this extension throws an error ( restservice is my appID):
---------------------------
Microsoft Visual Studio
---------------------------
Dapr
Unable to launch the application: An element with the same key but a different value already exists. Key: '${restservice:appPort}'
---------------------------
OK
---------------------------
This is supported (and intended) by dapr, and invoking dapr run -f dapr.yaml works perfectly fine.
