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:

5个选项:

Fill in the documentation comments (great, but time-consuming) Turn off the comment generation (in project properties) Disable the warning in project properties (in 'Project properties' go to Project properties -> Build > "Errors and warnings" (section), Suppress Warnings (textbox), add 1591 (comma separated list)). By default it will change Active Configuration, consider to change configuration to All. Use #pragma warning disable 1591 to disable the warning just for some bits of code (and #pragma warning restore 1591 afterwards) Ignore the warnings (bad idea - you'll miss new "real" warnings)

当然要向公开可见的类型和成员添加XML注释:)

///<Summary>
/// Gets the answer
///</Summary>
public int MyMethod()
{
   return 42;
}

所有成员都需要这些<summary>类型的注释——这些注释也会显示在智能感知弹出菜单中。

得到此警告的原因是因为您已经将项目设置为输出文档xml文件(在项目设置中)。这对于类库(.dll程序集)很有用，这意味着.dll的用户可以在visual studio中获得API的智能感知文档。

我建议你买一份GhostDoc Visual Studio插件。使记录变得更容易。

一个非常简单的方法是在.csproj文件中添加一个属性:

<Project>
    <PropertyGroup>
        ...     
        <!--disable missing comment warning-->
        <NoWarn>$(NoWarn);1591</NoWarn>
    </PropertyGroup>
...

在这里的后面，但是这个线程中的许多解决方案都专注于在项目或类中完全删除警告。

如果你想保留合法的警告，但删除一些-例如，当你使用swagger公开API时，WebApi控制器上的cancellationToken (API用户不需要这个-它是由DI提供的)。

很难看，但至少在这种情况下，取消令牌是最后一个参数。

    /// <summary>
    /// Creates a Service
    /// </summary>
    /// <param name="service">The Service Definition</param> (**note no cancellation token param**)
    /// <returns>A newly created item</returns>
    /// <response code="201">Returns the newly created service</response>
    /// <response code="400">If there are validation errors with the submitted json body</response>
    /// <response code="409">Conflict. The service already exists</response>
    /// <response code="500">Because life is never perfect</response>
    [ProducesResponseType(typeof(Service), 201)]
    [ProducesResponseType(400)]
    [ProducesResponseType(409)]
    [ProducesResponseType(500)]
    [HttpPost]
    public async Task<ActionResult> ServiceCreate([FromBody] ServicePostRequest service,
#pragma warning disable 1573  
        CancellationToken cancellationToken = default) //**note: no warning**
#pragma warning restore 1573
    {

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
