系统崩溃后，我重新安装了VS并提出了解决方案。现在，它在Microsoft代码中得到一个重新定义错误。下面的示例输出：
2>Compressor.xaml.cpp
....
2>c:\program files (x86)\windows kits\10\include\10.0.17763.0\winrt\windows.foundation.numerics.h(349): warning C4099: 'Windows::Foundation::Numerics::Rational': type name first seen using 'class' now seen using 'struct' (compiling source file Compressor.xaml.cpp)
2>c:\program files (x86)\windows kits\10\include\10.0.17763.0\winrt\windows.foundation.numerics.h(567): error C2371: 'ABI::Windows::Foundation::Numerics::Rational': redefinition; different basic types (compiling source file Compressor.xaml.cpp)
2>c:\program files (x86)\windows kits\10\include\10.0.17763.0\winrt\windows.foundation.numerics.h(349): note: see declaration of 'ABI::Windows::Foundation::Numerics::Rational' (compiling source file Compressor.xaml.cpp)

仅供参考：我在代码中没有使用理性。
在解决此问题之前，该项目已无效。有想法吗？
