当我尝试查看任何 *.xaml 页面时,我看到的是错误消息,“ System.UnauthorizedAccessException 错误 5:访问被拒绝:'C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETCore\v4 .5\Microsoft.CSharp.dll' "
只是将“ C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETCore\v4.5\Microsoft.CSharp.dll ”添加到我的路径中,还是...?
