WPF .net 4 应用程序无法在 Windows 7 上正常运行
WPF .net 4 application does not work properly on Windows 7
我在 Visual Studio 2012 Express for Desktop on Windows 8 上创建了一个 WPF 应用程序，C# 目标框架 = .Net Framework 4。
当我 运行 Windows 7 中的程序时，它 运行s 但工作不正确。例如：当您单击按钮时，不会调用单击事件。在 Windows 7 上安装了 .Net Framework 4。
也不会发生任何错误。根本不起作用任何按钮。如果你 运行 变成 Windows 8，那么一切正常。
用 FUSLOGVW.exe 测试。
