The name for localdb appears to be sqlchangeautomation_ + a guid. I'm using Azure Devops deployment using sql change automation, when I use an agent name that is longer than 4 characters and use localdb in the build, I get an error message that states there is a path error. The generated localdb name is in the pattern sqlchangeautomation_ + a guid. This causes by builds to fail because part of the path is longer than 256 characters when the product is putting the necessary object into the user temp directory. if the pattern for generating the localdb name was something shorter like SCA_ + a guid that would save 17 characters in the path length and would let me use a build agent user with a name of 21 characters long instead of only 4 long. An alternate to this would be to allow the path to be overridden from the user temp directory (using the user environment variable TEMP to a shorter path root via a setting in the product.
