EF.Utility.CS.ttinclude and MSBuild

I am having troubles getting my MSBuild script transform a .tt file that references EF.Utility.CS.ttinclude.

If i run the generation from withi开发者_JAVA百科n VS2010 it works fine, but when I run my custom build script via the command line I get.

 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'.

If I reference the absolute path for the EF.Utility.CS.ttinclude, I get:

  TextTransform "C:\SourceControl\SVN\PathToFile\myttFile.tt"

Any help would be great :)

In short: Add the -I flag in TextTransform.exe to solve this problem like so:

Step 1: Create an environment variable mapping to your TextTransform's EF6 Include like so:

which will create a variable VS140COMNTXTTRANSFORM that Windows understands

Step 2: Include -I flag in the TextTransform.exe command like so:

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

Appears that the template you were running myttFile.tt failed out output anything as a result of the template being executed TransformText();

Can't really tell much without seeing what the logic is inside of myttFile.tt.

Visual Studio 11 if you

set <# template debug = true#>

and add System.Diagnostics.Debugger.Launch(); to the code section of your template, VS 11 will launch the debugger and you can debug your t4.

sorry, just dawned on me. Chances are your template has a dependency on visual studio as its host. somewhere in your templates you have hostspecific = true.

<#@ template hostspecific="true" language="C#" #>
