使用UnitOfWorkOptions选项中的IsTransactional属性来禁用事务性UoW。具体的代码示例如下所示：

public class MyService : IMyService { private readonly IRepository _entityRepository; private readonly IUnitOfWorkManager _unitOfWorkManager;

public MyService(IRepository entityRepository, IUnitOfWorkManager unitOfWorkManager)
{
    _entityRepository = entityRepository;
    _unitOfWorkManager = unitOfWorkManager;
}

public async Task DoSomethingAsync()
{
    using (var uow = _unitOfWorkManager.Begin(new UnitOfWorkOptions { IsTransactional = false }))
    {
        // Do some work with _entityRepository
        await _entityRepository.InsertAsync(new MyEntity { Name = "Test" });
        await _unitOfWorkManager.Current.SaveChangesAsync();

        // Commit the unit of work
        await uow.CompleteAsync();
    }
}

}

通过将IsTransactional属性设置为false来禁用事务性UoW，我们可以在处理高负载时避免出现问题。
