I try make like this

https://learn.microsoft.com/pl-pl/visualstudio/data-tools/create-a-simple-data-application-with-wpf-and-entity-framework-6?view=vs-2022

This also not help -> Scaffold-DbContext "Server=(localdb)\MSSqlLocalDB;Database=Northwind;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

Any ideas ?

Answer 1

Try another new project: "Aplikacja WPF (.NET Framework)".

Answer 2

This is not supported in VS 2022. Instead open the nuget package manager console and type the following command for the project:

Scaffold-DbContext -provider Microsoft.EntityFrameworkCore.SqlServer -connection "Data Source=Your server; Initial Catalog=your database; trusted_connection=true"
