Turns out my project was not connecting to the SQL server and creating any database table. My bad, but learnt how to do it properly now. Great video for those starting out with SQL server and Entity Framework [LINK] [this video] Also, in my VS 19 .NET desktop development the App.config file is not created automatically. No problem, just create it from Add New Item. (Not sure what all needs to be added but for now just the connectionString item works.)

As you observed, the function addHourRow adds data to a data structure (I can't see what kind) in the browser's page state, but doesn't do anything to change the data at its source, in your database. To update the database, you'll need to add a request handler to a controller [LINK] , and call the controller from your javascript code.

I was following a tutorial for code first which is in this link: [this video] I was trying to mix this and a demo for REST API to both things. My connection string is the one below: <ConnectionString> <add name="RestApiDemo.Models.ProductsDbContext" connectionString=" data source=localhost; initial catalog=RestApiDemo; integrated security=SSPI" providerName="System.Data.SqlClient" ></add> </ConnectionString> When I run the command enable-migrations in the console it generates the migration folder and file correctly but then I get an exception. This doesn't let me work with Code First despite having generated the file correctly. The exception is the following: Exception screenshot [LINK] Migration
