💥Table Already Exists

Error: Table 'tablename' already exists

Description: This error may occur when the Migrations folder is deleted and recreated, leading to conflicts in the database schema.

Exception Message:

MySqlConnector.MySqlException: Table 'aspnetroles' already exists

Solution: To resolve this issue, you can drop the foodservice schema and then try running the application again. Follow these steps:

1. Connect to your SQLServer database using a tool like SSMS or via command line.

2. Execute the following command to drop the foodservice schema:

   DROP SCHEMA foodservice;

3. Run the application again to allow Entity Framework to recreate the schema and apply migrations.

Example Code: If you encounter this error while running the following code snippet, the above steps should resolve it:

/// <summary>
/// Updates the database migration if there are pending migrations.
/// </summary>
/// <param name="services">The service collection.</param>
public static void UpdateMigrationDatabase(this IServiceCollection services)
{
    // Configure database migration
    using (var scope = services.BuildServiceProvider().CreateScope())
    {
        using (var dbContext = scope.ServiceProvider.GetRequiredService<AppDbContext>())
        {
            if (dbContext.Database.GetPendingMigrations().Any())
            {
                dbContext.Database.Migrate();
            }
        }
    }
}

By dropping the schema and retrying, you should be able to avoid conflicts caused by existing tables and ensure a clean migration.
