From the beginning of SaaS story of NAV, when it became a Business Central we had “Tenant Management” codeunit with very useful functions
Such functions as IsSandbox(), IsProduction(), GetTenantId() i used quite a lot.
When I tested my extension against Business Central Wave 2 I’ve got this error message
Simple investigations didn’t help. “Tenant Management” codeunit – disappeared.
I had to recreate Wave 2 NavContainer with -includeAL tag and then get Al code source code with Create-AlProjectFolderFromBcContainer as Freddy described here.
This gave me a full copy of AL source files, where I searched for isSandbox and found it in the “Environment Information” codeunit.
Replacing “Tenant Management” to “Environment Information” solved my problem.
And the source code of Environment Information could be found here https://github.com/microsoft/ALAppExtensions/tree/master/Modules/System/Environment%20Information
Update from Rafal Babaczyk here is the list of all breaking changes https://github.com/microsoft/ALAppExtensions/blob/master/BREAKINGCHANGES.md#azure-ad-tenant-module
