SQLiteAsyncConnection UpdateWithChildren 不可用

我正在尝试使用 SQLite.net 在我的 PCL 内实现 OneToMany 关系。我有异步扩展包（SQLiteNetExtensions.Async），并且我的代码基于中找到的示例https://bitbucket.org/twincoders/sqlite-net-extensions https://bitbucket.org/twincoders/sqlite-net-extensions。我正在使用 SQLiteAsyncConnection，但 UpdateWithChildren 方法似乎不可用，只能使用 SQLiteConnection。

using SQLite.Net;
using SQLite.Net.Async;
using SQLite.Net.Interop;
using SQLiteNetExtensions.Extensions;

private readonly SQLiteAsyncConnection conn;
public ActivityRepository(ISQLitePlatform platform, string dbPath)
{
    var connectionFactory = new Func<SQLiteConnectionWithLock>(() => new SQLiteConnectionWithLock(platform, new SQLiteConnectionString(dbPath, storeDateTimeAsTicks: true)));
    conn = new SQLiteAsyncConnection(connectionFactory);
}
public void method(object object) {
    conn.UpdateWithChildren(object); --function not available
}

使用时SQLiteAsyncConnection，你必须使用异步 Nuget 包 https://www.nuget.org/packages/SQLiteNetExtensions.Async/, SQLiteNetExtensionsAsync.Extensions所有方法的命名空间和异步版本：

using SQLite.Net;
using SQLite.Net.Async;
using SQLite.Net.Interop;
using SQLiteNetExtensionsAsync.Extensions;

private readonly SQLiteAsyncConnection conn;
public ActivityRepository(ISQLitePlatform platform, string dbPath)
{
    var connectionFactory = new Func<SQLiteConnectionWithLock>(() => new SQLiteConnectionWithLock(platform, new SQLiteConnectionString(dbPath, storeDateTimeAsTicks: true)));
    conn = new SQLiteAsyncConnection(connectionFactory);
}
public Task method(object object) {
    return conn.UpdateWithChildrenAsync(object);
}

请注意，所有异步方法都会返回一个Task必须等待或返回。
