asp.net-mvc - "The OutputPath property is not set for project"设置 OutputPath 时

Question

在 MVC4 中，如果我为解决方案中的所有项目创建一个新的构建配置，则在单独构建 web .csproj 时会得到以下信息:

msbuild Company.Directory.Web.csproj /p:Configuration=Dev

[Error] C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(483, 9): The OutputPath property is not set for project 'Company.Directory.Web.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Dev' Platform='AnyCPU'. You may be seeing this message because you are trying to build a project without a solution file, and have specified a non-default Configuration or Platform that doesn't exist for this project.

然而， OutputPath属性设置!

这是一个错误吗？我该如何解决？

原来，第一个PropertyGroup很重要。 Visual Studio 插入了新配置 (Dev) PropertyGroup由于某种原因在它之前。我猜它是一个错误。我通过在其他配置之后移动新配置来修复它。
