不包含 ListItemAllFields 的定义

Question

我有以下代码：

public void ChangeFolderPermission()
{
    SP.ClientContext ctx = new SP.ClientContext("https://sharepoint.oshirowanen.com/sites/oshirodev/");
    ctx.Credentials = new NetworkCredential("user", "pass", "domain");

    SP.Principal user = ctx.Web.EnsureUser("accountName");
    var folder = ctx.Web.GetFolderByServerRelativeUrl("folderUrl");
    var roleDefinition = ctx.Site.RootWeb.RoleDefinitions.GetByType(SP.RoleType.Reader);  //get Reader role
    var roleBindings = new SP.RoleDefinitionBindingCollection(ctx) { roleDefinition };
    folder.ListItemAllFields.BreakRoleInheritance(true, false);  //set folder unique permissions
    folder.ListItemAllFields.RoleAssignments.Add(user, roleBindings);
    ctx.ExecuteQuery();  
}

但以下几行：

folder.ListItemAllFields.BreakRoleInheritance(true, false);  //set folder unique permissions
folder.ListItemAllFields.RoleAssignments.Add(user, roleBindings);

给出此错误消息：

'Microsoft.SharePoint.Client.Folder' does not contain a definition for 'ListItemAllFields' and no extension method 'ListItemAllFields' accepting a first argument of type 'Microsoft.SharePoint.Client.Folder' could be found (are you missing a using directive or an assembly reference?)

我有以下项目参考资料

Microsoft.SharePoint.Client
microsoft.SharePoint.Client.Runtime

我有以下使用指令

using SP = Microsoft.SharePoint.Client;

知道我为什么会收到此错误吗？

该应用程序是从桌面环境运行的 winform。

这是因为 SharePoint 2010 文件夹 API 没有 "ListItemAllFields" 属性 - 它是在 2013 年添加的。
