问题现象
一个以前使用.NET Framwork 3.0框架开发的项目，在框架升级到.NET Framwork 4.7.2后，
如下代码：
#pragma checksum "..\..\XpsViewer.xaml" "{8829d00f-11b8-4213-878b-770e8597ac16}" "4141923E04B8F37EBAC5AA6FD24010A2242046815AD9C4F159F31F5E02A435EE"
//------------------------------------------------------------------------------

// 此代码由工具生成。
// 运行时版本:4.0.30319.42000
//
// 对此文件的更改可能会导致不正确的行为，并且如果
// 重新生成代码，这些更改将会丢失。

报如下错误：

解决方案
根据错误提示，其实就是需要添加System.Xaml的引用。
添加方法如下：
在项目引用处右键——添加引用——程序集——勾选上“System.Xaml”
如图：
