我们正在考虑各种框架和语言选项来为我们的目标市场开发我们的数据库驱动的桌面应用程序，不幸的是，在他们的系统中大量使用 Windows XP。任何人都可以确认，如果我们在 C#/.NET 框架 4.0 中开发桌面应用程序，该应用程序是否能够在 Windows XP 上运行？我知道要运行 .net 开发的应用程序，我们需要在最终用户的系统中安装 .net 框架，所以我的第二个问题是：我们可以在 Windows XP 上安装 .net 框架（没有安装服务包）吗？等待您的专家解答启发。

It's not clear why you think you've got two questions here - they're both basically "does .NET 4 run on Windows XP" which is easily answered by the system requirements page.
That shows that .NET 4 works on XP Professional, XP Home Edition and XP Professional x64 edition. It does not work (or at least isn't supported) on Media Center, Tablet PC or Starter editions.
I would expect it to be an optional install via Windows Update, so you may find that some of your customers already have it installed, but plenty of others don't.
