I don't have time to implement a tool for implementing CRUD. Wouldn't it be better to not have so many layers of abstraction that you need a tool in the first place?
Let me elaborate on what it took me to implement a CRUD controller.
I had to implement a repository interface, a respository a context, a service interface, and a controller. Then I had to understand how to write the swagger documentation. Then there is a convention of wrapping every result and exception in some kind of wrapper, which is not documented so I had to figure this out from looking at other controllers.
Then I saw a execution path for another CRUD controller which could throw an error which was not in this wrapper, so I had to discuss this with someone from the team. Sure enough, he is in another country, and takes a while to respond. I was lucky it was still morning, or he would have gone home already (there's a 4 hour time difference). Sure enough, this was a bug in the other controller.
Then, there is a logging and a monitoring service I had to understand and implement. Undocumented, of course. The controller I used as a reference was inconsistent in monitoring, so I had to discuss this. Then, the requirements for the controller are not clear. The RESTful way of responding to a GET request for a nonexisting resource would be a 404, but the wrapper does not allow this. The reference controller returns 200 OK, but with a null value. So I had to check if this is indeed what's intended.
Then I had to figure out how the unit testing framework works and I had to write tests for each method. OK, good practice, but it feels a bit weird, since the unit tests should not use the database while the entire purpose of the CRUD controller is to use the database. So much of the logic I'm supposed to test is mocked. So, I had to learn how the mocking framework works. Then I wanted to write unit tests for the repository, but entity framework crashes when I use an in-memory database. The other developers had a look, but didn't understand this either. The other repository implementations are not tested anyway, so I skipped this.
Additionally, visual studio crashed, corrupted my git repository, and I ended up deleting and cloning the whole repo again. Then, I had to configure the project again before it would build, which involves opening the project in an older version of visual studio, then opening the same project in the latest version (some errors magically disappear), and adjusting the IIS settings (which are a mystery to me).
I also had a long meeting to attend, and the person who's supposed to get me started didn't have time to help me. In the end, I'm still not quite happy with the actual logic in the controller (it has inconsistencies similar to the controller I used as a reference), but I refuse to spend more time on it.
