我有一个.NET MAUI移动的应用程序，我试图实现一个SearchHandler与数据绑定从ViewModel。
我有下面的代码，但我得到了“没有属性，BindableProperty，或事件发现“客户端”，或不匹配的类型之间的值和属性”错误。
单位：ClientPage.xaml

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

             xmlns:sh="clr-namespace:Realizer.Resources.SearchHandlers"
             xmlns:models="clr-namespace:Realizer.Models"
             x:DataType="vm:ClientsViewModel"
             x:Class="Realizer.Pages.ClientsPage"
             Title="Clients">
    
    <Shell.SearchHandler>
        <sh:ClientSearchHander ShowsResults="True"
                               Clients="{Binding Clients}"
                               DisplayMemberName="Name">
            
        </sh:ClientSearchHander>
    </Shell.SearchHandler>

namespace Realizer.Resources.SearchHandlers

    {
        //public static readonly BindableProperty Clients;
        public ObservableCollection<Client> Clients { get; set; }

        {
            base.OnQueryChanged(oldValue, newValue);
            if(string.IsNullOrWhiteSpace(newValue))
            {
                ItemsSource = null;
            }
            else
            {
                ItemsSource = Clients.Where(x => x.Name.Contains(newValue)).ToList();

public partial class ClientsViewModel : ObservableObject

        [ObservableProperty]
        private ObservableCollection<Client> _clients = new();
       
        public async Task LoadClientsAsync()

           if (clients is not null && clients.Any())//if we have at least one client
           {
               Clients ??= new ObservableCollection<Client>(); //if null, initialize

               foreach (var client in clients)
               {
                   Clients.Add(client);

我看到有人问同样的问题here，并试图使Clients在ClientSearchHandler.csBindableProperty正如我所评论的。但它发生冲突时，我设置Client.Where(...)说“'BindableProperty' does not contain a definition for 'Where'”。
