没有为Silverlight输出指定Silverlight项目

Question

我有一个非常标准的Silverlight应用程序在ASP.NET主机下运行.在所有开发机器上,它编译得很好,但在我们的CI服务上,我们收到此错误:

没有为Silverlight输出指定Silverlight项目

但是,如果我登录CI并使用VS2010手动编译,它工作正常!这是Silverlight 4,.NET 4.0

Answer 1

因为我花了两天时间试图弄清楚为什么在我工作的Silverlight项目中发生这种情况,我想我会在这里发布它.

在我的情况下,问题是由于网站的.csproj中的一个<ProjectReference>有一个项目GUID与项目的实际GUID不匹配(由于之前发生的代码重组).

这与silverlight应用程序或其任何设置无关.我不知道为什么,但不知何故,这个错误的引用导致"CopyFilesToFolders"MSBuild任务在"SourceFiles"列表中多次列出相同的文件.这会导致第一组copys成功,然后是一组"No Silverlight project specified"错误.

只需删除错误的项目引用并重新添加它就修复了GUID并解决了构建问题.

确实是一个非常糟糕的错误消息.

Answer 2

感谢MerickOWA在这里发布,我相信它可以节省我同样的问题.

我创建了一个PowerShell脚本来查找解决方案中所有项目的不匹配GUID.它可以为其他人节省更多时间.

要运行它,下面的代码复制到一个文本文件在同一文件夹作为您的解决方案,重命名为.PS1,启动PowerShell控制台,导航到该文件夹​​包含您的解决方案,然后运行该脚本.它将列出错误匹配的项目引用(如果有).

要解决此问题,请在Visual Studio中打开解决方案,然后删除并重新添加不匹配的Project Reference(s).

    "Validating solution: " + $slnFileName

    # Extract all the c# projects from the solution file
    $solutionProjects =
