Entity framework 4 EF.Utility.CS.t包含和MSBuild

我在获取引用EF.Utility.CS.ttinclude的.tt文件的MSBuild脚本转换时遇到问题

如果我在VS2010中运行生成，它可以正常工作，但是当我通过命令行运行自定义构建脚本时，我会得到

 TextTransform "C:\SourceControl\SVN\PathToFile\myttFile.tt"
C:\SourceControl\SVN\PathToFile\myttFile.tt(9,4): error : There was an error loading the include file 'EF.Utility.CS.ttinclude'. The transformation will not be run. The following Exception was thrown: [C:\SourceControl\SVN\PathToBuildScript\build.xml]
  System.IO.FileNotFoundException: Could not find file 'C:\SourceControl\SVN\PathToFile\EF.Utility.CS.ttinclude'.

C:\SourceControl\SVN\PathToBuildScript\build.xml(30,5): error MSB3073: The command "TextTransform "C:\SourceControl\SVN\PathToFile\myttFile.tt"" exited with code 1.

如果我引用EF.Utility.CS.t包含的绝对路径，我会得到：

  TextTransform "C:\SourceControl\SVN\PathToFile\myttFile.tt"
EXEC : error : An expression block evaluated as Null [C:\SourceControl\SVN\PathToBuildFile\build.xml]

任何帮助都很好：）

显示您正在运行的模板myttFile.tt由于执行模板TransformText（）而输出任何内容失败

如果看不到myttFile.tt中的逻辑，就很难说出什么

VisualStudio11如果您

设置

加 System.Diagnostics.Debugger.Launch（）； 在模板的代码部分，VS11将启动调试器，您可以调试t4

对不起，我刚明白过来。您的模板很可能依赖visual studio作为其宿主。在模板中的某个地方，您有hostspecific=true

简而言之：在TextTransform.exe中添加-I标志以解决此问题，如下所示：

第1步： 创建一个映射到TextTransform的EF6的环境变量，如下所示：

这将创建一个Windows能够理解的变量VS140COMNTXTTRANSFORM

第二步： 在textcransform.exe命令中包括-I标志，如下所示：

TextTransform.exe -I "%VS140COMNTXTTRANSFORM%" -out filename.tt

您是否尝试过使用-I开关调用texttransform.exe以及EF.Utility.CS.ttinclude的路径？路径可能是：c:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\Entity Framework Tools\Templates\Includes\或c:\Program Files（x86）\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\Entity Framework Tools\Templates\Includes\很好，其他解决方案都不起作用
