我已经把头撞在墙上了几天.似乎没有任何Google搜索或弄乱的答案.

我想在构建时运行T4模板.在其中,我需要访问在该项目之前构建的程序集中的类型.我需要msbuild才能构建它,并且msbuild与VS变量配合不好,因此我需要使用另一种方式来加载程序集.

我读过很多地方,T4ReferencePath是设置从中加载自定义程序集的地方的答案.但是,我无法使其正常工作.

当我指定时：

<T4ReferencePath Include="$(TargetDir)" />

当我尝试在VS中加载项目或使用msbuild运行它时,我得到了这个：

d:\Users\250894\Documents\Visual Studio 2013\Projects\TestT4\TestT4.csproj(90,22): error MSB4066: The attribute "Include" in element <T4ReferencePath> is unrecognized.

我确实安装了“ Visual Studio可视化和建模SDK”.

我为简短起见而道歉,但是我将包含测试项目的整个.csproj文件,以防万一我明显错过了一些明显的内容.我没有包含.tt文件,因为即使我无法加载cproj也不相关.如果我排除T4ReferencePath,则说明一切正常.

解决方法:

我终于迷失了答案.我无法想象以前没有人遇到过这种情况,但是我们来了.希望我已经开辟了一条道路,将对那些追随者提供帮助.

尽管常识告诉我,T4ReferencePath不是“属性”.这是一个“项目”.当我从“ PropertyGroup”中删除它并将其添加到“ ItemGroup”中时,它很高兴.

通常,软件开发和计算机使用的弊端之一是无益的错误消息.我不能说这是我遇到过的最糟糕的例子,但是它就在那里.
