Declaration

C#

public class EFCoreObjectSpaceProvider :
    IObjectSpaceProvider,
    IDatabaseSchemaChecker,
    IDisposable

VB.NET

Public Class EFCoreObjectSpaceProvider
    Implements IObjectSpaceProvider,

Remarks

In applications with the Security System, use the SecuredEFCoreObjectSpaceProvider instead of EFCoreObjectSpaceProvider.

The following example shows how to create EFCoreObjectSpaceProvider in a non-XAF application.

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.EFCore;
using Microsoft.EntityFrameworkCore;
using System;
using System.Configuration;
// ...
class Program {
    static void Main() {
        string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
        EFCoreObjectSpaceProvider objectSpaceProvider = new EFCoreObjectSpaceProvider(typeof(ApplicationDbContext),
            (builder, _) => builder.UseSqlServer(connectionString));
        // ...
    }
}
