如何在VS2010中指定使用C#4.0的T4(文本模板)？

Question

我需要指定我的T4使用C#4.0来渲染我的tt文件？我试过用

<#@ template language="C#v4.0" debug="true" #>

但是当我使用动态变量时,就像这样

dynamic x=10;
Write(x.ToString());

我收到这些错误

Error   2   Compiling transformation: Predefined type 'Microsoft.CSharp.RuntimeBinder.CSharpSetMemberBinder' is not defined or imported e:\projects\DynamicModel\DynamicModel\ModelGenerator.tt 1   1   
Error   3   Compiling transformation: Missing compiler required member 'Microsoft.CSharp.RuntimeBinder.CSharpInvokeMemberBinder..ctor'  e:\projects\DynamicModel\DynamicModel\ModelGenerator.tt 1   1   
Error   4   Compiling transformation: Missing compiler required member 'System.Runtime.CompilerServices.CallSite.Create'    e:\projects\DynamicModel\DynamicModel\ModelGenerator.tt 1   1   
Error   5   Compiling transformation: One or more types required to compile a dynamic expression cannot be found. Are you missing references to Microsoft.CSharp.dll and System.Core.dll?   e:\Projects\DynamicModel\DynamicModel\ModelGenerator.tt 7   8   
Error   6   A namespace cannot directly contain members such as fields or methods   e:\projects\DynamicModel\DynamicModel\ModelGenerator.cs 1   1   DynamicModel

另外,请注意,我用TextTemplatingFileGenerator和不预处理器模板

发现您还应该指定正确的程序集.

添加此项将确保您使用的是c#4.0.

<#@ template language="C#" debug="true" #>
<#@ output extension=".txt" #>
<#@ Assembly Name="System.Core, Version=4.0.0.0, Culture=neutral" #>
<#@ Assembly Name="Microsoft.CSharp, Version=4.0.0.0, Culture=neutral" #>

但是,出于某种原因,在t4转换期间,动态调度仍然无法从T4开始工作,不知道为什么.从T4开始会抛出运行时错误,相同的代码直接从cs文件中获得好处.
