I know this is a really old thread, but it's the first response on google so I thought I'd add this bit of information: This behavior only occurs when the warning level is set to 4 under "Project Properties" -> "Build". Unless you really need that much information you can set it to 3 and you'll get rid of these warnings. Of course, changing the warning level affects more than just comments, so please refer to the documentation if you're unsure what you'll be missing: https://msdn.microsoft.com/en-us/library/thxezb7y.aspx

来自@JonSkeet的答案几乎完成了。如果您想为解决方案中的每个项目禁用它，可以将下面的行添加到.editorconfig文件中。

dotnet_diagnostic.CS1591.severity = none

查看文件层次结构和优先级添加文件的位置:

https://learn.microsoft.com/en-us/visualstudio/ide/create-portable-custom-editor-options?view=vs-2019#file-hierarchy-and-precedence

还有另一种方法可以抑制这些消息，而不需要任何代码更改或pragma块。使用Visual Studio -转到项目属性>构建>错误和警告>抑制警告-将1591附加到警告代码列表。

In your solution, once you check the option to generate XML Document file, it start checking your public members, for having the XMLDoc, if they don't, you'll receive a warning per each element. if you don't really want to release your DLL, and also you don't need documentations then, go to your solution, build section, and turn it off, else if you need it, so fill them, and if there are unimportant properties and fields, just surpass them with pre-compiler instruction #pragma warning disable 1591 you can also restore the warning : #pragma warning restore 1591

Pragma用法:在代码中任何你得到编译器警告的地方之前…(对于文件，把它放在头文件中，你不需要再次启用它，对于单个类环绕一个类，或方法环绕一个方法，或…你也不需要把它包装起来，你可以随意地调用它并恢复它(在文件的开始处开始，并在方法中结束))，编写以下代码:

#pragma警告禁用1591 如果你需要恢复它，使用: #pragma警告恢复1591

这里有一个例子:

using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using MongoDB.Bson;
using MongoDB.Bson.Serialization.Attributes;
using RealEstate.Entity.Models.Base;

namespace RealEstate.Models.Base
{
    public class CityVM
    {

#pragma warning disable 1591

        [Required]
        public string Id { get; set; }

        [Required]
        public string Name { get; set; }

        public List<LanguageBasedName> LanguageBasedNames { get; set; }

        [Required]
        public string CountryId { get; set; }

#pragma warning restore 1591

        /// <summary>
        /// Some countries do not have neither a State, nor a Province
        /// </summary>
        public string StateOrProvinceId { get; set; }
    }
}

注意，pragma指令从行首开始

我想对这里列出的答案补充一些东西:

正如Isak所指出的，XML文档对于类库非常有用，因为它为Visual Studio中的任何消费者提供了智能感知。因此，一个简单而正确的解决方案是关闭任何顶级项目(如UI等)的文档，因为它不会在自己的项目之外实现。

此外，我想指出的是，警告只表示在公开可见的成员。因此，如果将类库设置为只公开它需要公开的内容，则无需记录私有成员和内部成员。
