Good to know
System symbols now included with Business Central server
Starting with update 26.3, Business Central server binaries now include the system symbols instead of the System extension. As a result, you can't publish SymbolsOnly packages by using the Publish-NAVApp cmdlet. You get a warning if you use the -SymbolsOnly parameter with the Get-NAVAppInfo cmdlet. To get information about the system symbols, use the -Name System parameter.
