Mark,

It sounds like you are using T4 Toolbox and trying to create partial .tt files with Template and Generator classes. These files are not meant to be transformed by T4. Click here for details.

Hope this helps,
Oleg

We have provided a standard (DSL Tools) Text tempalte that is able to call a GAX Template and pass in the parameters very nicely.
Please take a look here:

ok…
i figured it out.
my property was:

and should be:

<#@ property name=”Tables” type=”System.Collections.Generic.List, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089″ processor=”PropertyProcessor” #>

Thanks, Ali. Yes, it is possible to use T4 templates hosted in a standalone application. TextTransform.exe is an example of such an application. Unfortunately, it doesn’t provide a built-in mechanism for passing parameter values. You could pass parameters via an external (XML?) file referenced in the template itself. Otherwise, you could build a custom T4 Host which could provide this capability similar to how GAT host does it with the arguments dictionary.

hi oleg,
thanks for the articles and posts, think that they are useful and clear.
i wonder if it is possible to use t4 templates hosted in a standalone application and provide on the fly parameter passing mechanism (by engine or host)

I was getting an EntryPointNotFoundException on the line:

string output = engine.ProcessTemplate(template, host);

I had to dig out Microsoft.VisualStudio.TextTemplating.dll version 8.1.0.0 to get that line to work.
