T4模板错误

Question

错误是：

Error   48  A processor named 'PropertyProcessor' could not be found for the directive named 'property'. The transformation will not be run.  The following Exception was thrown:
System.IO.FileNotFoundException: Failed to resolve type for directive processor PropertyProcessor.
   at Microsoft.VisualStudio.TextTemplating.VSHost.TextTemplatingService.ResolveDirectiveProcessor(String processorName)
   at Microsoft.VisualStudio.TextTemplating.Engine.ProcessCustomDirectives(ITextTemplatingEngineHost host, TemplateProcessingSession session, List`1 directivesToBeProcessed)   Config.tt   2   4   

T4模板是：

<#@ template language="C#" #>
<#@ property name="serverName" processor="PropertyProcessor" type="System.String" #>

using System;   

如何修复此错误？什么意思？

Answer 1

<#@属性#>是一个自定义指令。Visual Studio中的T4主机不支持它。您可以使用GAX主机，也可以提供PropertyProcessor的替代实现，例如Clarius Consulting的T4编辑器中包含的实现。更多here。
