C# Petapoco tt文件错误

尝试在petapoco中保存tt文件时出现此错误。我已经从nuget package manager在类库上安装了petapoco，但它没有按预期创建自动生成的模型文件夹。因此，对于play around，我从旧项目复制了models文件夹，并将其放在类库中，并在App.config文件中指定了连接字符串配置。并提供了正确的连接字符串名称和命名空间值。但我仍然面临着这个错误

我在Dapper.SimpleCrud的文本模板中遇到了同样的问题，并且正在寻找VS 2017版本15.5的解决方案，尽管VS 2017预览版15.5没有问题（参考Microsoft.CodeDom.Providers.DotNetCompilerPlatform）

同时，希望下面的解决方法能让您继续前进：

右键单击.tt文件，然后单击“调试T4模板”

我发现我无法在类库中生成模型文件夹，甚至在asp.net mvc core 1.1项目中也无法生成模型文件夹。试图探索原因，有解决方案吗？这里也有同样的问题。我以为在做了一些更改，关闭VS并重新打开后它被修复了，但它又回来了。这仍然是一个问题。
