  Hello,

  if the UI in Visual Studio does not allow for it, you can always edit the .csproj directly and make the adjustments needed. You're looking for <PackageReference> entries.

  Example in VS Code:

  Example in Visual Studio: Double Click on your *.EntityFrameworkCore Project

  It will then open the .csproj file for you to edit

  Does that help you?

  Kind regards Jack

  I have downloaded the fresh solution from abp commercial. Now without making any changes im trying to build all projects. Im able to build all project wituout any issue except "PublicWeb" project under "apps" folder.

  

  Im getting below error even though the project file has the reference to the G1.Clinic.Doctorz.ProductService.HttpApi.Client.csproj : Severity Code Description Project File Line Suppression State Error NU1105 Unable to find project information for 'D:\G1_abp\G1.Clinic.Doctorz\services\product\src\G1.Clinic.Doctorz.ProductService.HttpApi.Client\G1.Clinic.Doctorz.ProductService.HttpApi.Client.csproj'. If you are using Visual Studio, this may be because the project is unloaded or not part of the current solution so run a restore from the command-line. Otherwise, the project file may be invalid or missing targets required for restore. G1.Clinic.Doctorz.PublicWeb D:\G1_abp\G1.Clinic.Doctorz\apps\public-web\src\G1.Clinic.Doctorz.PublicWeb\G1.Clinic.Doctorz.PublicWeb.csproj 1

  Similar behaviour is not happening for any other reference project like EntityFrameworkCore.

  Hi Support,

  Could you please provide detailed steps to migrate to mysql database for microservices template. we are using the url: https://docs.abp.io/en/abp/latest/Entity-Framework-Core-MySQL to migrate and swithch the sql database to mysql.

  When we ran the migrator project we are getting below errors:

  Failed executing DbCommand (33ms) [Parameters=[@__providerName_0='?' (Size = 64)], CommandType='Text', CommandTimeout='30'] SELECT "a.Id, a.Name, a.ProviderKey, a.ProviderName, a.Value FROM AbpSettings AS a WHERE (a.ProviderName = @__providerName_0) AND a.ProviderKey IS NULL" [13:34:30 ERR] An exception occurred while iterating over the results of a query for context type 'G1.Microservice.AdministrationService.EntityFrameworkCore.AdministrationServiceDbContext'.

  When we run the migration on individual service host we get following error; Starting G1.Microservice.AdministrationService.HttpApi.Host. [17:15:15 FTL] G1.Microservice.AdministrationService.HttpApi.Host terminated unexpectedly! Microsoft.Extensions.Hosting.HostAbortedException: The host was aborted. at Microsoft.Extensions.Hosting.HostFactoryResolver.HostingListener.ThrowHostAborted() at Microsoft.Extensions.Hosting.HostFactoryResolver.HostingListener.OnNext(KeyValuePair`2 value) at System.Diagnostics.DiagnosticListener.Write(String name, Object value) at Microsoft.Extensions.Hosting.HostBuilder.ResolveHost(IServiceProvider serviceProvider, DiagnosticListener diagnosticListener) at Microsoft.Extensions.Hosting.HostApplicationBuilder.Build() at Microsoft.AspNetCore.Builder.WebApplicationBuilder.Build() at G1.Microservice.AdministrationService.Program.Main(String[] args) in F:\AbpSuiteMicroservices\G1.Microservice\services\administration\src\G1.Microservice.AdministrationService.HttpApi.Host\Program.cs:line 28 To undo this action, use Remove-Migration.

  Hey,

  So here are my steps according to the documentation: I had to make some adjustments. If you exactly to the steps I describe here, you should be fine to go (as they worked out for me).

  Step 1 - Replace packages

  all good

  Step 2 - Replace module dependency

  ✅ all good

  Step 3 - UseMySql()

  ⚠️ Changed things

  This is okay:

  YourProjectNameEntityFrameworkCoreModule.cs inside the .EntityFrameworkCore project. Replace UseSqlServer() with UseMySQL().
  

  This is something I made a bit different:

  YourProjectNameDbContextFactory.cs inside the .EntityFrameworkCore project. Replace UseSqlServer() with UseMySql(). Then add a new parameter (ServerVersion) to UseMySql() method. Example: .UseMySql(configuration.GetConnectionString("Default"), ServerVersion.Parse("8.0.21-mysql")). See this issue for more information about ServerVersion)
  

  My change looks like this:

  public AdministrationServiceDbContext CreateDbContext(string[] args)
      {
          AdministrationServiceEfCoreEntityExtensionMappings.Configure();
  
          var connectionString = GetConnectionStringFromConfiguration();
  
          var builder = new DbContextOptionsBuilder<AdministrationServiceDbContext>()
              .UseMySql(connectionString, ServerVersion.AutoDetect(connectionString), b =>
              {
                  b.MigrationsHistoryTable("__AdministrationService_Migrations");
              });
  
          return new AdministrationServiceDbContext(builder.Options);
      }
  

  *In addition to that, some of the ServiceDbContext.cs file needed more adjustment.

  before:

  protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
      {
          optionsBuilder.ConfigureWarnings(w => w.Ignore(SqlServerEventId.SavepointsDisabledBecauseOfMARS));
          base.OnConfiguring(optionsBuilder);
      }
  

  after:

  protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
      {
          base.OnConfiguring(optionsBuilder);
      }
  

  Step 4 - Change Connection string

  pretty straight forward.

  My new connection string look like this:

  "ConnectionStrings": {
      "ProductService": "server=127.0.0.1;port=3306;user=mysuperduperuser;pwd=mysuperduperpasswort;database=Doctorz_ProductService",
      "IdentityService": "server=127.0.0.1;port=3306;user=mysuperduperuser;pwd=mysuperduperpasswort;database=Doctorz_Identity",
      "AdministrationService": "server=127.0.0.1;port=3306;user=mysuperduperuser;pwd=mysuperduperpasswort;database=Doctorz_Administration",
      "SaasService": "server=127.0.0.1;port=3306;user=mysuperduperuser;pwd=mysuperduperpasswort;database=Doctorz_Saas"
    },
  

  Step 5 - Create new migrations

  Did exactly what the docs told me

  ⚠️ Adjustments needed to be made

  First: Deleted everything inside the migrations folders Second: executed dotnet build /graphBuild on solution level Third: Wanted to add initial migrations

  PM> Add-Migration "Initial"
  Build started...
  Build succeeded.
  The Entity Framework tools version '7.0.1' is older than that of the runtime '7.0.2'. Update the tools for the latest features and bug fixes. See https://aka.ms/AAc1fbw for more information.

  Microsoft.Extensions.Hosting.HostAbortedException: The host was aborted.

  To undo this action, use Remove-Migration.
  

  Used this answer https://stackoverflow.com/a/76170042

  my program.cs now looks like this:

  public async static Task<int> Main(string[] args)
      {
          var assemblyName = typeof(Program).Assembly.GetName().Name;
  
          SerilogConfigurationHelper.Configure(assemblyName!);
  
          try
          {
              Log.Information($"Starting {assemblyName}.");
              var builder = WebApplication.CreateBuilder(args);
              builder.Host
                  .AddAppSettingsSecretsJson()
                  .UseAutofac()
                  .UseSerilog();
              await builder.AddApplicationAsync<AdministrationServiceHttpApiHostModule>();
              var app = builder.Build();
              await app.InitializeApplicationAsync();
              await app.RunAsync();
              return 0;
          }
          catch (Exception ex) when (ex is not HostAbortedException)
          {
              Log.Fatal(ex, $"{assemblyName} terminated unexpectedly! \nEX: {ex}\nStackTrace: {ex.StackTrace}\nINNER{ex.InnerException}");
              return 1;
          }
          finally
          {
              Log.CloseAndFlush();
          }
  

  After that, I was able to create the migrations.

  I executed dotnet build /graphBuild again just to ensure I did everything correctly (solution still buildable) and it went through.

  Fourth: Run the DbMigrator

  [16:01:56 INF] Loaded ABP modules:
  ...
  [16:01:56 DBG] Started background worker: Volo.Abp.OpenIddict.Tokens.TokenCleanupBackgroundWorker

  To automatically close the console when debugging stops, enable Tools->Options->Debugging->Automatically close the console when debugging stops.
  Press any key to close this window . . .
  

  Step 4 - Run the application

  ⚠️

  adjust run-tye.yaml. You do not need sql-server-db. you may replace it with mysql server also adjust ms sql stuff from build/etc/docker to match your requirements

  Now, execute run-tye.ps1 from the solution directory.
