类型'System.Collections.Generic.ISet [Model.InputFieldVisibility]没有默认的构造函数。参数名称：type

Question

我正在使用Asp.net core 2.1，在我的本地主机上一切正常，但是在部署后出现此错误： 类型'System.Collections.Generic.ISet'1 [Model.InputFieldVisibility]'没有默认的构造函数。参数名称：type。这是我的控制器：

public class InputFieldVisibilityController : ControllerBase
{
    private readonly UserManagementProvider _userManagementProvider;
    private readonly Log _log;
    private readonly SharedLocalizer _sharedLocalizer;
    public InputFieldVisibilityController(UserManagementProvider userManagementProvider, 
                                Log log, SharedLocalizer sharedLocalizer)
    {
        this._userManagementProvider = userManagementProvider;
        this._sharedLocalizer = sharedLocalizer;
        this._log = log;
    }
    [HttpGet("getAll/{idUser}/{entity}")]
    public ISet<InputFieldVisibility> getAll(string idUser, string entity)

        criteria.CreateAlias("user", "user", NHibernate.SqlCommand.JoinType.LeftOuterJoin);
        criteria.Add(Restrictions.Eq("user.id", int.Parse(idUser)));


        criteria.Add(Restrictions.Eq("entity",

有人对此问题背后的原因有任何想法吗？ 谢谢。
