Can any one tell me if I can use .net 3.5 in T4 inside my guidance???

I'm trying to just call a partial method. Here is a sample:

<#@ template language="C#v3.5" debug="True" #>
<#@ property processor="PropertyProcessor" name="ClassName" #>
<#@ property processor="PropertyProcessor" name="TargetNamespace" #>
<#@ property processor="PropertyProcessor" name="Hello" #>
<#@ assembly name="F:\DotNet\Factory\GuidancePackage1\PartialMethods\bin\Debug\PartialMethods.dll" #>
<#@ Assembly Name="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" #>
<#@ import namespace="PartialMethods" #>
<#@ assembly name="System.dll" #>

using System;
using System.Text;

namespace <#= TargetNamespace #>
{
class <#= ClassName #>
{
static void Main(string[] args)
{
Console.WriteLine("<#= Hello #>");
Console.WriteLine("<#= "Write Day".ConcatenaDiaHora() #>");
Console.ReadLine();
}
}
}


here is the error

Microsoft.Practices.RecipeFramework.ActionExecutionException: An exception occurred during the binding of reference or execution of recipe AddMainClass. Error was: Action GenerateMainClass failed to execute:
Exception of type 'Microsoft.Practices.RecipeFramework.VisualStudio.Library.Templates.TemplateException' was thrown..
You can remove the reference to this recipe through the Guidance Package Manager. ---> An invalid language 'C#v3.5' was specified in the 'template' directive. The language must be either "C#" or "VB". The default value of "C#" will be used.

why can't I use C#v3.5 in T4 in my guidance???
Can any one tell how can i do it and a sample please....

Hi Pedro,

this is a known issue of GAX and most probably will be fixed in a hotfix that should be available soon (we're working on it right now)
in the meantime what you can do is add the following redirects in you devenv.exe.config

<dependentAssembly>
<assemblyIdentity name="Microsoft.VisualStudio.TextTemplating" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Microsoft.VisualStudio.TextTemplating.VSHost" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
</dependentAssembly>

(it just applies for Vs2008)
those redirects fix the issue.

Regarding the template that you've posted remember that you should use just the assembly name or a path so when you put
<#@ Assembly Name="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" #>
should be
<#@ Assembly Name="System.Core.dll" #>

hope it helps
jose.

Jose,
Is there there any information you can give us on the status of the hotfix you mentioned in the above post? I tried adding he redirects to my devenv.exe.config file, but it didn't help any. Could that be because I was using the guidance package in a VS instance that was running in the experimental hive?
