无法部署RazorPages网站

我建立了一个简单的Razor Pages网站，以显示几个数据库表的一些视图。

在index.cshtml.cs我只是有：

public class IndexModel : PageModel
{
    public IActionResult OnGet()
    {
        return RedirectToPage("./Registrations/Index");
    }
}

在Registrations/index.cshtml.cs我有：

public class IndexModel : PageModel
{
    int pageSize = 30;

    private readonly RegistrationAdmin.PostgresDbContext _context;

    public IndexModel(RegistrationAdmin.PostgresDbContext context)
    {
        _cOntext= context;
    }

    public PaginatedList Registration { get; set; }

    public async Task OnGetAsync(int pageIndex = 1)
    {
        IQueryable registratiOns= _context.Registrations
            .Include(r => r.ContactPerson)
            .Include(r => r.Badge)
            .OrderByDescending(r => r.RegistrationId);

        this.Registration = await PaginatedList.
                            CreateAsync(registrations.AsNoTracking(), pageIndex, pageSize);
    }
}

从Visual Studio测试网站很好，从项目目录运行dotnet run也可以。

因此，我通过以下方式部署了该网站：

dotnet publish -o ../Published/ -c release

然后dotnet MyWebsite.dll从发布目录运行它。

当我连接到http：// localhost：5000时，出现一般错误。

查看控制台，这是抛出的异常：

Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]

我无法理解已部署的版本出了什么问题。
