1.WebGrease
未能加载文件或程序集“WebGrease, Version=1.5.1.25624, Culture=neutral, PublicKeyToken=31bf3856ad364e35”或它的某一个依赖项。找到的程序集清单定义与程序集引用不匹配。 (异常来自 HRESULT:0x80131040) 

解决方法

通过"uninstall-package -f WebGrease"先卸载，然后通过"install-package WebGrease"再下载最新版本，问题解决。

关于使用NuGet程序包卸载和安装：
● 查看版本：到https://www.nuget.org
● 删除程序包：uninstall-package -f WebGrease
● 安装某个版本的程序包：install-package WebGrease -Version 1.3.0

This issue was resolved by upgrading from WebGrease 1.5.2 to 1.6.0 as well as updating Microsoft.AspNet.Web.Optimization

Install-Package Microsoft.AspNet.Web.Optimization
Update-Package WebGrease
Uninstall-Package Microsoft.AspNet.Web.Optimization
Uninstall-Package WebGrease
Install-Package Microsoft.AspNet.Web.Optimization
Update-Package WebGrease
