c# - T4模板错误

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模板为：

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

using System;

我该如何解决此错误？这是什么意思？

最佳答案

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 Editor中包含的一种。更多here。
