Put All methods in one .tt file and use it in another t4 files in CodeTemplates of MVC

问题

I use ASP.NET MVC 3 Custom CodeTemplates I need to put some methods in one t4 file and then use it in all my t4 templates.

So this is my general.tt file:

<#@ template language="C#" #>
<#@ assembly name="System" #>
<#@ assembly name="System.Core" #>
<#@ assembly name="System.ComponentModel.DataAnnotations" #>
<#@ assembly name="System.Data" #>
<#@ assembly name="System.Data.Entity" #>
<#@ assembly name="System.Data.Linq" #>
<#@ assembly name="System.Xml.Linq" #>
<#@ import namespace="System" #>
<#@ import namespace="System.Linq" #>
<#@ import namespace="System.Text" #>
<#@ import namespace="System.Collections.Generic" #>
<#@ import namespace="System.ComponentModel.DataAnnotations" #>
<#@ import namespace="System.ComponentModel" #>
<#@ import namespace="System.Data.Linq.Mapping" #>
<#@ import namespace="System.Data.Objects.DataClasses" #>
<#@ import namespace="System.Reflection" #>
<#@ import namespace="Microsoft.VisualStudio.Web.Mvc.Scaffolding.BuiltIn" #>

<#+ 
public class XXD {
    public string getitNow(){
        return "Yup thats it!";
    }
}
 #>

Then I use it in create.tt file like this:

<#@ include file="general.tt" #>

...

<#+

private string GetitNow(){
   XXD xx = new XXD();
   return xx.getitNow();
}

but there is an error when I want to Add View Use create template:

error: Loading the included file 'general.tt' returned a null or empty string. The transformation will not be run.

So where is the problem? what is your suggestion to do this?

回答1:

Last time I checked, the MVC scaffolding still used a custom implementation of the ITextTemplatingEngineHost, which implements the include directive differently than the ITextTemplating service in Visual Studio. I suggest for you to submit a Connect bug, describe the problem you are experiencing and ask to change the T4 implementation in MVC to the built-in ITextTemplating service, which does not have this and other limitations.

回答2:

That normally means that the file isn't found. Is general.tt in a different path to create.tt?
