WPF窗口类需要vb.net导入吗？

Imports System.Windows
Imports System.Windows.Controls

Public Class MainWindow
    Inherits Window

    Public Sub New()
        ' 设置窗口标题和大小
        Me.Title = "WPF窗口示例"
        Me.Width = 400
        Me.Height = 300

        ' 创建一个按钮控件
        Dim button As New Button()
        button.Content = "点击我"
        button.Width = 100
        button.Height = 30

        ' 将按钮添加到窗口中
        Me.Content = button
    End Sub

End Class

Public Class App
    Inherits Application

    Protected Overrides Sub OnStartup(ByVal e As StartupEventArgs)
        MyBase.OnStartup(e)

        ' 创建并显示主窗口
        Dim mainWindow As New MainWindow()
        mainWindow.Show()
    End Sub

End Class

Module Module1

    Sub Main()
        ' 启动应用程序
        Dim app As New App()
        app.Run()
    End Sub

End Module
