Describe the bug

Affects

Microsoft.EntityFrameworkCore.Design Version="10.0.0"

Exception see during a Migration Worker service after upgrading Microsoft.EntityFrameworkCore.Design to version 10.

The following function is used to ensure the database is created.

private static async Task EnsureDatabaseCreatedAsync(DbContext dbContext, CancellationToken cancellationToken)
    {
        var dbCreator = dbContext.GetService<IRelationalDatabaseCreator>();

        var strategy = dbContext.Database.CreateExecutionStrategy();
        await strategy.ExecuteAsync(async () =>
        {
            if (!await dbCreator.ExistsAsync(cancellationToken))
            {
                await dbCreator.CreateAsync(cancellationToken);
            }
        });
    }

Called in context

var mainDbContext = new SomeDbContext(
      new DbContextOptionsBuilder<SomeDbContext>()
          .UseNpgsql(configuration.GetConnectionString("db"), contextOptionsBuilder =>
              contextOptionsBuilder.ConfigureDataSource(dataSourceBuilder =>
                  dataSourceBuilder.EnableDynamicJson()
                      .EnableAzureActiveDirectoryAuthentication()))
          .UseAsyncSeeding(async (context, _, cancellationToken) =>
          {
              if (environment.IsDevelopment())
              {
                  await SeedDataAsync(context, cancellationToken);
              }
          })
          .Options);

  await EnsureDatabaseCreatedAsync(mainDbContext, stoppingToken);
  await RunMigrationAsync(mainDbContext, stoppingToken);

The following exception is seen on line var dbCreator = dbContext.GetService<IRelationalDatabaseCreator>();:

System.MissingMethodException: Method not found: 'System.String

Downgrading Microsoft.EntityFrameworkCore.Design to Version="9.0.11" resolves this issue.

I tried searching https://learn.microsoft.com/en-us/ef/core/what-is-new/ef-core-10.0/breaking-changes

Expected Behavior

IRelationalDatabaseCreator is resolved.

Steps To Reproduce

public class MigrationService(IServiceProvider serviceProvider, IHostApplicationLifetime hostApplicationLifetime)
    : BackgroundService
{
    public const string ActivitySourceName = "Migrations";

    private static readonly ActivitySource ActivitySource = new(ActivitySourceName);

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        using var activity = ActivitySource.StartActivity("Migrating database", ActivityKind.Client);

        try
        {
            using var scope = serviceProvider.CreateScope();

            var configuration = scope.ServiceProvider.GetRequiredService<IConfiguration>();
            var environment = scope.ServiceProvider.GetRequiredService<IHostEnvironment>();

            var mainDbContext = new SomeDbContext(
                new DbContextOptionsBuilder<SomeDbContext>()
                    .UseNpgsql(configuration.GetConnectionString("db"), contextOptionsBuilder =>
                        contextOptionsBuilder.ConfigureDataSource(dataSourceBuilder =>
                            dataSourceBuilder.EnableDynamicJson()
                                .EnableAzureActiveDirectoryAuthentication()))
                    .UseAsyncSeeding(async (context, _, cancellationToken) =>
                    {
                        if (environment.IsDevelopment())
                        {
                            await SeedDataAsync(context, cancellationToken);
                        }
                    })
                    .Options);

            await EnsureDatabaseCreatedAsync(mainDbContext, stoppingToken);
            await RunMigrationAsync(mainDbContext, stoppingToken);
        }
        catch (Exception ex)
        {
            activity?.AddException(ex);
            throw;
        }

        hostApplicationLifetime.StopApplication();
    }

    private static async Task EnsureDatabaseCreatedAsync(DbContext dbContext, CancellationToken cancellationToken)
    {
        var dbCreator = dbContext.GetService<IRelationalDatabaseCreator>();

        var strategy = dbContext.Database.CreateExecutionStrategy();
        await strategy.ExecuteAsync(async () =>
        {
            if (!await dbCreator.ExistsAsync(cancellationToken))
            {
                await dbCreator.CreateAsync(cancellationToken);
            }
        });
    }

    private static async Task RunMigrationAsync(DbContext dbContext, CancellationToken cancellationToken)
    {
        var strategy = dbContext.Database.CreateExecutionStrategy();
        await strategy.ExecuteAsync(async () =>
        {
            await dbContext.Database.MigrateAsync(cancellationToken);
        });
    }

    private static async Task SeedDataAsync(SitesDbContext context, CancellationToken cancellationToken)
    {
// obscured
    }
}

Anything else?

No response

Looks like this issue should be transferred to dotnet/efcore as it doesn't appear to be specific to ASP.NET Core.
