Fixed: "Failure processing application bundle. DOTNET_BUNDLE_EXTRACT_BASE_DIR is not set, and a read-write cache directory couldn't be created."
I built an EF Core migrations bundle, ran it, and got three lines instead of migrations: Failure processing application bundle. Failed to determine location for extracting embedded files. DOTNET_BUNDLE_EXTRACT_BASE_DIR is not set, and a read-write cache directory couldn't be created. The bundle was fine. The folder it extracts into, ~/.net, had belonged to root since 2023.
