Local assembly registration

Hi,
I created a U-SQL class library project MyLibrary and separately created a U-SQL project MyProject. I built the U-SQL class library and registered it with the (local-project: MyProject) ADLA account. I added REFERENCE ASSEMBLY MyProject; to my U-SQL script, but when I try to submit the script to the local-project account I get the message "Assembly 'master.MyLibrary' does not exist.

Is there a way to list the assemblies registered with the project?
Do I need to take any other steps to test the assembly locally?

The steps I've taken so far follow the documentation here: https://blogs.msdn.microsoft.com/azuredatalake/2016/08/26/how-to-register-u-sql-assemblies-in-your-u-sql-catalog/
