SecuredEFCoreObjectSpace Class

An Object Space for EF Core-based applications that use the Security System.

Namespace: DevExpress.EntityFrameworkCore.Security

Assembly: DevExpress.EntityFrameworkCore.Security.v24.1.dll

NuGet Package: DevExpress.ExpressApp.EFCore

Declaration

public class SecuredEFCoreObjectSpace :
    EFCoreObjectSpace,
    ISessionObjectProvider

Remarks

XAF creates Object Spaces of the SecuredEFCoreObjectSpace type in the following cases:

The following example demonstrates how to use SecuredEFCoreObjectSpaceProvider<TDbContext> to create SecuredEFCoreObjectSpace in a non-XAF application.

using DevExpress.EntityFrameworkCore.Security;
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Security;
using DevExpress.Persistent.Base;
using DevExpress.Persistent.BaseImpl.EF.PermissionPolicy;
using Microsoft.EntityFrameworkCore;
using System.Configuration;
// ...
class Program {
    static void Main() {
        AuthenticationStandard authentication = new AuthenticationStandard();
        SecurityStrategyComplex security = new SecurityStrategyComplex(
            typeof(PermissionPolicyUser), typeof(PermissionPolicyRole),
            authentication
        );
        var objectSpaceProvider = new SecuredEFCoreObjectSpaceProvider<ApplicationDbContext>(security,
            XafTypesInfo.Instance, ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString,
            (builder, connectionString) => builder.UseSqlServer(connectionString)
        );
        // ...
        IObjectSpace securedObjectSpace = objectSpaceProvider.CreateObjectSpace();
    }
}
