c# - Petapoco tt文件错误

Question

尝试在 petapoco 中保存 tt 文件时出现此错误。我已经从类库上的 nuget 包管理器安装了 petapoco，但它没有按预期创建自动生成的模型文件夹。所以为了玩玩，我从我的旧项目中复制了模型文件夹并将其放在类库中，并在 App.config 文件中指定了我的连接字符串配置。并提供了正确的连接字符串名称和命名空间值。但我仍然面临这个错误。

Answer 1

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

同时，希望下面的解决方法可以让您继续前进:

Right click .tt file and then "Debug T4 Template"
