  1. Solution The error comes from the OpenIddict data seeder in Microservicev10.IdentityService: “CS0103: The name ‘_configuration’ does not exist in the current context”. In ABP v10 microservice templates, OpenIddict seeding in the IdentityService HttpApi.Host project reads settings from IConfiguration via DI; if you moved/added a seeder class or created a new service and copied code, you likely lost the injected IConfiguration field.

  Fix it by injecting IConfiguration (or using GetRequiredService<IConfiguration> from the service provider) and using it where _configuration is referenced.

  Option A: Constructor inject IConfiguration in the seeder

  • File: services/identity/Microservicev10.IdentityService/Microservicev10.IdentityService.csproj project, inside Data/OpenIddict/OpenIddictDataSeeder.cs (or DataSeeder.cs where the error points)
  • Replace your class header with DI for IConfiguration and assign to a private field.

  Example:

  using Microsoft.Extensions.Configuration;
  using Volo.Abp.DependencyInjection;
  using Volo.Abp.Data;
  
  namespace Microservicev10.IdentityService.Data.OpenIddict;
  
  public class OpenIddictDataSeeder : IDataSeedContributor, ITransientDependency
  {
      private readonly IConfiguration _configuration;
      // other injections...
  
      public OpenIddictDataSeeder(
          IConfiguration configuration
          /* other dependencies */
      )
      {
          _configuration = configuration;
          // assign others...
      }
  
      public async Task SeedAsync(DataSeedContext context)
      {
          // Use _configuration["OpenIddict:Applications:MyClient:RootUrl"] etc.
          // Your existing seeding logic...
      }
  }
  

  Option B: Resolve IConfiguration on demand If you already have IServiceProvider injected, resolve configuration when needed:

  public async Task SeedAsync(DataSeedContext context)
  {
      var configuration = _serviceProvider.GetRequiredService<IConfiguration>();
      var rootUrl = configuration["OpenIddict:Applications:MyClient:RootUrl"];
      // ...
  }
  

  Common places that use _configuration in OpenIddict seeders:

  • Reading OpenIddict Applications (clients) and Scopes from appsettings.json:
    • OpenIddict:Applications:...
    • OpenIddict:Scopes:...
  • Building redirect/logout URLs with RootUrl values.

  Also ensure the seeder runs:

  • IdentityService.HttpApi.Host typically triggers OpenIddict seeding in its DbMigrations/OpenIddictDataSeeder during migration or host initialization. If you created a new microservice and added an OpenIddict seeder into the service project (not DbMigrator or IdentityService.HttpApi.Host DbMigrations), make sure it implements IDataSeedContributor and the host calls IDataSeeder.SeedAsync on startup or you run DbMigrator.

  hi

  There is no _configuration in your OpenIddictDataSeeder.cs file

  Can you run dotnet build command and check the output in your IdentityService?

  

  Thanks.

  Sorry, the OpenIddictDataSeeder file I sent in the previous email was one that I had already modified myself, so it didn’t contain _configuration.

  I have created a new project and I’m currently experiencing the same error. I will send you the new OpenIddictDataSeeder file from the fresh project. Below is the output I got after running the dotnet build command as you requested.

  hi

  It seems your local template package is outdated.

  Can you try to clear your nuget cache and run abp new command again?

  dotnet nuget locals -c all
  
  abp new Microservicev101 -t microservice --ui-framework angular --mobile react-native --database-provider ef --database-management-system sqlserver --theme leptonx --skip-migrator --public-website --without-cms-kit --dont-run-bundling -no-file-management -no-language-management
  

  You will see: **Volo.Abp.Studio.Extensions.StandardSolutionTemplates (v: 2.0.2) **

   Volo.Abp.Studio.Extensions.StandardSolutionTemplates (v: 2.0.2) extension trying install from the NuGet
  📌 ABP CLI 2.0.2

  Hello Maliming, I am experiencing the same issue when creating a new Microservice project. I followed the instructions above, but I’m still getting an error related to _configuration in IdentityService. volo.abp.studio.cli 2.0.2 abp volo.abp.suite 10.0.0 abp-suite I hope you can respond soon so I can continue my work. Thank you.

  Thank you for your response. We have encountered another issue and hope you can assist us. When using ABP Suite to generate an Entity for a CRUD Page, we are facing a problem related to missing namespace imports. We were able to resolve it manually by adding the appropriate namespace, and then we could continue working. We are reporting this issue to you and hope your team can address and fix it so that generating new Entities can be fully automated without this error. Thank you. Abp version: volo.abp.studio.cli 2.0.2 abp volo.abp.suite 10.0.0 abp-suite
