SecuredEFCoreObjectSpace Class

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

Namespace: DevExpress.EntityFrameworkCore.Security

Assembly: DevExpress.EntityFrameworkCore.Security.v20.2.dll

NuGet Package: DevExpress.ExpressApp.EFCore

Declaration

C#
VB.NET

public class SecuredEFCoreObjectSpace :
    EFCoreObjectSpace,
    ISessionObjectProvider

Public Class SecuredEFCoreObjectSpace
    Inherits EFCoreObjectSpace
    Implements ISessionObjectProvider

Remarks

If your application does not use the Security System, create the EFCoreObjectSpace instead of SecuredEFCoreObjectSpace.

In XAF application, use the XafApplication.CreateObjectSpace method to create this Object Space if the default Object Space Provider is SecuredEFCoreObjectSpaceProvider (see the CreateDefaultObjectSpaceProvider method implementation of your WinApplication descendant).

The following example demonstrates how to use SecuredEFCoreObjectSpaceProvider 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
        );
        SecuredEFCoreObjectSpaceProvider objectSpaceProvider = new SecuredEFCoreObjectSpaceProvider(
            security, typeof(ApplicationDbContext),
            XafTypesInfo.Instance, ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString,
            (builder, connectionString) => builder.UseSqlServer(connectionString)
        );
        // ...
        IObjectSpace securedObjectSpace = objectSpaceProvider.CreateObjectSpace();
    }
}
