I am currently learning Asp.net core Mvc (with vs 2019) and I have a question. I know I can create a model and with help of Scaffold create a local database through the program but I if I have already my own sample database, how I can insert it and show some details to web?
I’ve read about .Net framework and ADO.NET Entity Framework but this isnt working on Core version.
Followed Microsoft guides but they had only the “Seed Data” but i can’t make it work with my db Table.
Is there any way I can achive it? Or i have to recreate the project on .Net Framework ?

Method 1
As far as I know, we could use EF command line tool to scaffold existing sql database and generate the model folder according to the database’s table.
More details, you could refer to below steps:
I created a new MVC application to test, you could also add the package and run the ef scaffold.
1.Open CMD in your application
2.Run below command
mkdir DotnetEFCoreScaffoldMVC cd DotnetEFCoreScaffoldMVC dotnet new MVC dotnet add package Microsoft.EntityFrameworkCore.SqlServer dotnet add package Microsoft.EntityFrameworkCore.Design dotnet ef dbcontext scaffold "the connection string" Microsoft.EntityFrameworkCore.SqlServer -o Model
