How to delete a class from a Model

I was trying to follow a tutorial with zero knowledge of D365 programming. The tutorial gave a definition for class A. I created a project, added a new class and added the code for A. It didn't compile. I commented out some stuff just to make it compile and try to pin down the error. I eventually realised that a method in class A was referring to a Table in another Model. Now I want to:

Create a new Model for my stuff (when I created my project, it defaulted to the Fleet Management model, but I didn't know that, and I didn't know that I needed to know that);
Add the Package reference that I need (Update model parameters -> Select referenced packages -> ApplicationSuite);
Recreate class A from the tutorial in my new project based on my new Model.

However, I can't do (3) because it say that class A exists. I searched AOT and found that it exists in model Fleet Management. I right-clicked it hoping to see /Delete/ but no such luck.

I could probably proceed by renaming tutorial class A in my new project but since I littered Fleet Management I need to clean it up. How do I delete class A from package Fleet Management in AOT?

You have two options. Either create a project for Fleet Management (or open one if you already have it), add Class A there and delete it. You can't delete it directly in Application Explorer. Or delete the file directly on disk (not in Visual Studio).

Then rebuild Fleet Management module, to apply this change of source code to compiler binaries.

Thanks, Martin.

While waiting for a response, based on Googling and my build error messages ("Location of the log file is ..."), I eventually found it.

I located the files related to my class at
C:\AOSService\FleetManagement\FleetManagement\AxClass\A.xml
C:\AOSService\FleetManagement\XppMetadata\FleetManagement\AxClass\A.xml
C:\AOSService\PackagesLocalDirectory\bin\XppSource\FleetManagement\AxClass_A.xpp

I backed them up, deleted them, rebuilt the model (Visual Studio menu -> Extensions -> Dynamics 365\Build Models
Packages -> Fleet Management
Options
-> Build Pre-Compiled Form
-> Build Reports
-> Build Cross Reference Data
-> Synchronize Database

I don't know which of these were necessary.

Only the first one is relevant; that's the source code file.
