c# - Visual Studio 2012 发布 Web 项目与 MSBuild

Question

我向我的 MVC 应用程序添加了一个新配置。Visual Studio 2012 将配置块添加到 .csproj 的顶部。然后，当我尝试通过 msbuild 构建项目时：

msbuild WebApp.csproj /t:Clean;Build;_WPPCopyWebApplication /p:Configuration=QA;WebProjectOutputDir=c:\builds\webapp\qa

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(609,5): error : The OutputPath property is not set for project 'WebApp.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='QA' 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. [c:\code\WebApp.csproj]

有谁知道我如何在默认配置块之后添加新配置？一旦我将配置块与其他配置一起向下移动，MSBuild 就可以正常工作。

编辑以显示 Visual Studio 2012 如何添加配置：
