This is my modul EFCore DbContext

[ConnectionStringName(SinavDbProperties.ConnectionStringName)]  
public class SinavDbContext : AbpDbContext<SinavDbContext>, ISinavDbContext 
{
    public DbSet<ExamReport> ExamReports { get; set; } = null!;
    public DbSet<ExamOrder> ExamOrders { get; set; } = null!;
    public DbSet<ExamScore> ExamScores { get; set; } = null!;

    public DbSet<DersGrup> DersGrups { get; set; } = null!;
    public DbSet<Yayinevi> Yayinevis { get; set; } = null!;
    /* Add DbSet for each Aggregate Root here. Example:
     * public DbSet<Question> Questions { get; set; }
     */

    public SinavDbContext(DbContextOptions<SinavDbContext> options)
        : base(options)
    {

    }

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        builder.ConfigureIdentityPro();
        builder.ConfigureSinav();
    }

This is main project DbCOntext:

[ReplaceDbContext(typeof(IIdentityProDbContext))]
[ConnectionStringName("Default")]
public class EnDenemeDbContext :
    AbpDbContext<EnDenemeDbContext>,
    IIdentityProDbContext, IHasEventOutbox, IHasEventInbox[ReplaceDbContext(typeof(IIdentityProDbContext))]
[ConnectionStringName("Default")]
public class EnDenemeDbContext :
    AbpDbContext<EnDenemeDbContext>,
    IIdentityProDbContext, IHasEventOutbox, IHasEventInbox


  protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);

        /* Include modules to your migration db context */
       
        builder.ConfigurePermissionManagement();
        builder.ConfigureSettingManagement();
        builder.ConfigureBackgroundJobs();
        builder.ConfigureAuditLogging();
        builder.ConfigureIdentityPro();
        builder.ConfigureOpenIddictPro();
        builder.ConfigureFeatureManagement();
        builder.ConfigureLanguageManagement()
        ........
        builder.ConfigureSinav();: **This is module DbContext**

When I want to use IReporsitory<IdentityUser, Guid> this error throw
