I have developed a stand-alone ASP.Net Core/Razor Pages app using SQL Server.

I have been tasked with folding this app into a corporate database environment.

Unfortunately, the decision has been made that I am not allowed to use scaffolding, but I still must create full functionality (add new record/retrieve existing record/modify existing record) within the app.

All I have been able to find online is a tutorial that depends on scaffolding.

Any information on how to develop this functionality without scaffolding would be much appreciated.
