ASP.NET MVC3-使用MvcScaffolding模板添加新控制器时出错

Question

我正在尝试添加一个指定了以下模板的新控制器：

MvcScaffolding:具有读/写操作和视图的控制器，使用存储库

这在以前的项目中是有效的，但我现在从包管理器中获得了以下输出：

Scaffolding SubjectsController...
LibraryContext already has a member called 'Subjects'. Skipping...

知道发生了什么事吗？

Answer 1

当您安装T4Scaffolding包时，它会在powershell主机中注册它的程序集和包含的cmdlet。由于某些原因，它可能会从两个不同的位置加载T4Scaffolding包，并且您会得到“解析为不明确的cmdlet名称”错误，因为powershell无法决定执行哪个包cmdlet。正如我所看到的，你从"C:\Development\packages\MvcScaffolding.1.0.0\tools\RazorView\MvcScaffolding.RazorView.ps1“执行模板，它看起来像一个全局包，如果你在你的解决方案中本地安装了MvcsScaffolding - (SolutionFolder)\packages\MvcScaffolding.1.0.0 powershell可能会加载这两个包。

如果您从Visual Studio项目->右键->生成控制器生成控制器，它将作为Visual Studio插件来生成控制器，而不使用T4Scaffolding ->命令。
