On my task list for one of my customers was a nicely isolated module that I could make into an extension.
I’m a huge fan of making many small extensions rather than trying to put all of one customers modifications in one project.
In this case it is a side-by-side project with C/Side so I have created my own app file for the packages. I’ll see if I can blog somewhat about that later.
Extensions are not just for AppSource
Some people seem to think that on-premise we can just as well continue to use C/Side and even though I am a huge C/Side fan I have to disagree.
On-Premise extensions have a lot of value, especially because extensions enforce discipline.
The biggest challenge that I face when programming bespoke Extensions On-Premise is the deployment. Microsoft has made the testing of the license very strickt. In fact, it is more strickt than the runtime check which in my opinion is a bug. Microsoft however has a different opinion. Business Central in fall with the new license model solves it because then, there is no more license.
Everyone who has attended my Programming Master Class (800 of you) knows that using Temporary Tables as containers of code are one of the most powerful assets for clean code and reducing code cloning.
The Table behaves as a class with methods and properties and actually replaces the need for Code Units completely. Well, almost.
Using these tables in C/Side is free. It has always been free. End Users only have to pay for tables in their licenses if they write data to the database.
When you ship an extension with a table object that is outside of the customers license you’ll get an error message. The publishing process does not check your code for actual inserts and it probably could not even do that if they wanted to.
In C/Side end-users can import objects with a fob file that are outside of their license.
PowerShell to the Rescue
I’ve created a small PowerShell script that temporarily changes the license at the End-User and later switches it back. There is a lot of clean up to do but for me it was a huge time saver.
My plan is to somehow make this PowerShell script run directly from Visual Studio Code and launch the Windows Client instead of the Web Client.
Please not that I don’t dislike the Web Client but we have some pages in our solution that not yet render perfectly and have to be replaced first with another solution (probably Angular w. DevExpress).
Here is the script.
Don’t expect rocket science. I try to keep my PowerShell understandable.

The bottom two commands are commented out. I use them when I make schema changes to avoid having to create upgrade codeunits during the development process.
The Version and xVersion are because I like to keep some old versions of the .app file while I do the development. The UnInstall and UnPublish is not required if you increase the build number with each build
A tip to Microsoft would be to implement some of the old C/Side code into the Extensions module that only deleted data/colums for those tables/columns that were really changed.
I missed that 😉
But still sold through the Channel and not CSP?

Ok. Last info I got was that csp was just for cloud. Hope your right 👍😄

What is CSP ?
How can we reach MS to not have that license control when publish apps. Work around is to publish with developer licenses, but you need to restart the service to do the change and kick out everyone from working at the solution. This means that every small updates/ correction has to be done after work day (late), and turns out to not be a familiy friendly job. PS! all objects are in 76.000 serie but still got error.
Use Tenant Management codeunit (417)
It has functions for getting TenantID and if you are running i sandbox.
There is no voide number in SaaS
