In this post we will see how to configure Identity Service. In the identity service we have already add 2 modules Identity and IdentityServer. we need to configure the Identity service to use these modules.

Add the shared project as a reference to the host

We need to do the same thing we did in the admin service. Add the shared project as a reference and clean up host module.

<ProjectReference Include="..\..\..\..\shared\Tasky.Shared.Hosting\Tasky.Shared.Hosting.csproj" />

Update the connection string

User ID=postgres;Password=postgres;Host=localhost;Port=5432;Database=TaskyIdentityService;Pooling=false;

Update the IdentityServiceHttpApiHostModule

Update the depends on with the shared hosting module.


Remove the things which are configured in the shared project.

Create the DbContextFactory in the EntityFrameworkCore project

using System.IO;
using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using Microsoft.Extensions.Configuration;

namespace Tasky.IdentityService.EntityFrameworkCore;

public class IdentityServiceDbContextFactory : IDesignTimeDbContextFactory<IdentityServiceDbContext>
    public IdentityServiceDbContext CreateDbContext(string[] args)
        var builder = new DbContextOptionsBuilder<IdentityServiceDbContext>()

        return new IdentityServiceDbContext(builder.Options);

    private static string GetConnectionStringFromConfiguration()
        return BuildConfiguration()

    private static IConfigurationRoot BuildConfiguration()
        var builder = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json", false);

        return builder.Build();

Update the IdentityServiceDbContext

using Microsoft.EntityFrameworkCore;
using Volo.Abp.Data;
using Volo.Abp.EntityFrameworkCore;
using Volo.Abp.Identity;
using Volo.Abp.Identity.EntityFrameworkCore;
using Volo.Abp.IdentityServer.ApiResources;
using Volo.Abp.IdentityServer.ApiScopes;
using Volo.Abp.IdentityServer.Clients;
using Volo.Abp.IdentityServer.Devices;
using Volo.Abp.IdentityServer.EntityFrameworkCore;
using Volo.Abp.IdentityServer.Grants;
using Volo.Abp.IdentityServer.IdentityResources;

namespace Tasky.IdentityService.EntityFrameworkCore;

public class IdentityServiceDbContext : AbpDbContext<IdentityServiceDbContext>, IIdentityDbContext,
    IIdentityServerDbContext, IIdentityServiceDbContext
    public IdentityServiceDbContext(DbContextOptions<IdentityServiceDbContext> options)
        : base(options)

    public DbSet<IdentityUser> Users { get; set; }
    public DbSet<IdentityRole> Roles { get; set; }
    public DbSet<IdentityClaimType> ClaimTypes { get; set; }
    public DbSet<OrganizationUnit> OrganizationUnits { get; set; }
    public DbSet<IdentitySecurityLog> SecurityLogs { get; set; }
    public DbSet<IdentityLinkUser> LinkUsers { get; set; }
    public DbSet<ApiResource> ApiResources { get; set; }
    public DbSet<ApiResourceSecret> ApiResourceSecrets { get; set; }
    public DbSet<ApiResourceClaim> ApiResourceClaims { get; set; }
    public DbSet<ApiResourceScope> ApiResourceScopes { get; set; }
    public DbSet<ApiResourceProperty> ApiResourceProperties { get; set; }
    public DbSet<ApiScope> ApiScopes { get; set; }
    public DbSet<ApiScopeClaim> ApiScopeClaims { get; set; }
    public DbSet<ApiScopeProperty> ApiScopeProperties { get; set; }
    public DbSet<IdentityResource> IdentityResources { get; set; }
    public DbSet<IdentityResourceClaim> IdentityClaims { get; set; }
    public DbSet<IdentityResourceProperty> IdentityResourceProperties { get; set; }
    public DbSet<Client> Clients { get; set; }
    public DbSet<ClientGrantType> ClientGrantTypes { get; set; }
    public DbSet<ClientRedirectUri> ClientRedirectUris { get; set; }
    public DbSet<ClientPostLogoutRedirectUri> ClientPostLogoutRedirectUris { get; set; }
    public DbSet<ClientScope> ClientScopes { get; set; }
    public DbSet<ClientSecret> ClientSecrets { get; set; }
    public DbSet<ClientClaim> ClientClaims { get; set; }
    public DbSet<ClientIdPRestriction> ClientIdPRestrictions { get; set; }
    public DbSet<ClientCorsOrigin> ClientCorsOrigins { get; set; }
    public DbSet<ClientProperty> ClientProperties { get; set; }
    public DbSet<PersistedGrant> PersistedGrants { get; set; }
    public DbSet<DeviceFlowCodes> DeviceFlowCodes { get; set; }

    protected override void OnModelCreating(ModelBuilder builder)


Update the Tasky.IdentityService.EntityFrameworkCore project

Update the nuget packages with ef core packages. we will replace the module db context and configure the DbContext options in this module.

<PackageReference Include="Volo.Abp.EntityFrameworkCore" Version="5.1.4"/>
<PackageReference Include="Volo.Abp.EntityFrameworkCore.PostgreSql" Version="5.1.4"/>
<PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="6.0.1"/>

Update the IdentityServiceEntityFrameworkCoreModule file.

using System;
using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.EntityFrameworkCore;
using Volo.Abp.Identity.EntityFrameworkCore;
using Volo.Abp.IdentityServer.EntityFrameworkCore;
using Volo.Abp.Modularity;

namespace Tasky.IdentityService.EntityFrameworkCore;

public class IdentityServiceEntityFrameworkCoreModule : AbpModule
    public override void ConfigureServices(ServiceConfigurationContext context)
        Configure<AbpDbContextOptions>(options =>
        AppContext.SetSwitch("Npgsql.EnableLegacyTimestampBehavior", true);
        context.Services.AddAbpDbContext<IdentityServiceDbContext>(options =>


Once this is created delete EntityFrameworkCore folder can be created.


To create migrations

dotnet ef migrations add Init
