1. 会话状态管理

在应用开发中，会话状态的保存和恢复至关重要。以下是使用 C# 和 VB 实现会话状态保存和恢复的代码示例：

catch (Exception e)
{
    throw new SuspensionManagerException(e);
}

Public Shared Async Function SaveAsync() As Task
    Try
        ' Save the navigation state for all registered frames
        For Each weakFrameReference As WeakReference(Of Frame) In _registeredFrames

                SaveFrameNavigationState(frame)
            End If

        ' Serialize the session state synchronously to avoid asynchronous access to shared
        ' state
        Dim sessionData As New MemoryStream(
