Type	Description
String	The user name.

Remarks

For Windows Active Directory or Google, the ProviderUserKey property value is a Windows user name or a Google account ID, respectively. This value is unique for a specific provider, but different providers can have matching keys.

The LoginProviderName and ProviderUserKey form a unique combination. The ProviderUserKey is not necessarily unique among all providers but is always unique for a specific provider.

To support this unique combination, XAF does the following:

• Applies the Indexed attribute in XPO-based applications.

• Specifies that ISecurityUserLoginInfo.LoginProviderName and ISecurityUserLoginInfo.ProviderUserKey pairs should be unique in any override of the MySolutionDbContext.OnModelCreating method:

  C#

  using DevExpress.ExpressApp.Security;
  // ... 
  public class MySolutionDbContext : DbContext {
      //...
      public DbSet<ApplicationUser> Users { get; set; }
      public DbSet<ApplicationUserLoginInfo> UserLoginInfos { get; set; }
      protected override void OnModelCreating(ModelBuilder modelBuilder) {
          base.OnModelCreating(modelBuilder);
          modelBuilder.Entity<ApplicationUserLoginInfo>(b => {
              b.HasIndex(nameof(ISecurityUserLoginInfo.LoginProviderName), 
                  nameof(ISecurityUserLoginInfo.ProviderUserKey)).IsUnique();
          });
      }
  }
