  Dear Maliming

  Please as follow, the code is in the cwadmin.EntityFrameworkCore project, EntityFrameworkCore folder:

  [DependsOn(
      typeof(AbpZeroCoreEntityFrameworkCoreModule),
      typeof(cwadminCoreModule),
      typeof(AbpZeroCoreIdentityServerEntityFrameworkCoreModule)
      )]
  public class cwadminEntityFrameworkCoreModule : AbpModule
  {
      /* Used it tests to skip dbcontext registration, in order to use in-memory database of EF Core */
      public bool SkipDbContextRegistration { get; set; }
  
      public bool SkipDbSeed { get; set; }
  
      public override void PreInitialize()
      {
          if (!SkipDbContextRegistration)
          {
              Configuration.ReplaceService<IConnectionStringResolver, myConnectionStringResolver>();
  
              Configuration.Modules.AbpEfCore().AddDbContext<cwadminDbContext>(options =>
              {
                  if (options.ExistingConnection != null)
                  {
                      cwadminDbContextConfigurer.Configure(options.DbContextOptions, options.ExistingConnection);
                  }
                  else
                  {
                      cwadminDbContextConfigurer.Configure(options.DbContextOptions, options.ConnectionString);
                  }
              });
  
              Configuration.Modules.AbpEfCore().AddDbContext<cwTopologySwitchDbContext>(options =>
              {
                  if (options.ExistingConnection != null)
                  {
                      cwTopologySwitchDbContextConfigurer.Configure(options.DbContextOptions, options.ExistingConnection);
                  }
                  else
                  {
                      cwTopologySwitchDbContextConfigurer.Configure(options.DbContextOptions, options.ConnectionString);
                  }
              });
  
              Configuration.Modules.AbpEfCore().AddDbContext<cwCauDbContext>(options =>
              {
                  if (options.ExistingConnection != null)
                  {
                      cwCauDbContextConfigurer.Configure(options.DbContextOptions, options.ExistingConnection);
                  }
                  else
                  {
                      cwCauDbContextConfigurer.Configure(options.DbContextOptions, options.ConnectionString);
                  }
              });
  
  
              Configuration.Modules.AbpEfCore().AddDbContext<cwClientDbContext>(options =>
              {
                  if (options.ExistingConnection != null)
                  {
                      cwClientDbContextConfigurer.Configure(options.DbContextOptions, options.ExistingConnection);
                  }
                  else
                  {
                      cwClientDbContextConfigurer.Configure(options.DbContextOptions, options.ConnectionString);
                  }
              });
          }
  
          // Uncomment below line to write change logs for the entities below:
          Configuration.EntityHistory.Selectors.Add("cwadminEntities", EntityHistoryHelper.TrackedTypes);
          Configuration.CustomConfigProviders.Add(new EntityHistoryConfigProvider(Configuration));
      }
  
      public override void Initialize()
      {
          IocManager.RegisterAssemblyByConvention(typeof(cwadminEntityFrameworkCoreModule).GetAssembly());
      }
  
      public override void PostInitialize()
      {
          var configurationAccessor = IocManager.Resolve<IAppConfigurationAccessor>();
  
          using (var scope = IocManager.CreateScope())
          {
              if (!SkipDbSeed && scope.Resolve<DatabaseCheckHelper>().Exist(configurationAccessor.Configuration["ConnectionStrings:Default"]))
              {
                  SeedHelper.SeedHostDb(IocManager);
              }
          }
      }
  }
  

  It follows the recomendation for multiple databases found in https://stackoverflow.com/questions/49243891/how-to-use-multiples-databases-in-abp-core-zero/49572121#49572121

  Try Resolve IConnectionStringResolver under the PostInitialize method to see if it is correct?

  var connectionStringResolver = IocManager.Resolve<IConnectionStringResolver>();

  public override void PostInitialize()
  {
      var configurationAccessor = IocManager.Resolve<IAppConfigurationAccessor>();
      var connectionStringResolver = IocManager.Resolve<IConnectionStringResolver>();
      // ...
  }

  Dear Maliming

  Thank you for your feedback. Sorry, maybe my question was missleading. I would like to understand how I should register my own implementation if IConnectionStringResolver because Configuration.ReplaceService<IConnectionStringResolver, myConnectionStringResolver>(); does not work anymore with APB 4.1.0.

  Kind regards Andreas

  hi schneana.

  abp v4.1 did not modify the features you mentioned. https://github.com/aspnetboilerplate/aspnetboilerplate/releases/tag/v4.1.0

  Dear Maliming

  Many thanks for your feedback and for the link. You are right, investigating from the link I could trace down the issue. As usual the issue was infront of the keyboard, in this case I had a reference to Abp.Configuration.Startup. AbpStartupConfigurationExtensions was therefore not available togeter with the extesion on .ReplaceService<,>.

  Again many thanks for your swift response.

  Kind regard Andreas
