Question

我在我的项目中安装了MvcMailer包。所以我试图做脚手架，但它没有用。我用Google搜索了这个。我得到了应该安装的建议 T4Scaffolding 和MvcScaffolding

我做了哪些并重新启动了我的视觉工作室。但不幸的是从vs开始我的项目一些包不能很好地加载。脚手架包。似乎存在冲突。

错误消息如下：

Answer 1

我遇到了同样的问题，我可以按照以下步骤开展工作：

卸载 MvcMailer 。
卸载 MvcScaffolding 和 T4Scaffolding 。
在程序包管理器控制台中设置正确的默认项目。
从Scott自己here提到的命令 Install-Package MvcScaffolding -Version 1.0.8-vs2013 -Pre 运行此命令。
通过Nuget安装 MvcMailer 。
运行此命令 Scaffold Mailer.Razor UserMailer Welcome，PasswordReset

Answer 2

我知道这是在不久前发布的，但是，我在使用MvcScaffolding时在VS2015中遇到了同样的错误。实际的错误在于T4Scaffolding.Core包。我删除了源代码，修复了错误，并上传了带有链接依赖项的新NuGet包。 3个新包装是：

首先卸载MvcScaffolding及其依赖项，T4Scaffolding，＆amp; T4Scaffolding.Core。如果您只是安装MvcScaffolding包，其他包将被拉过来。希望这有助于其他人。如果这可以解决您的问题，请标记为已回答。

干杯。

Answer 3

首先运行

Uninstall-Package MvcScaffolding -RemoveDependencies
关闭VSTD并删除packages文件夹（如果还原了丢失的包裹）
重新打开项目
安装包MvcScaffolding -Version 1.0.8-vs2013 -Pre（如果您有VSTD 2013）

然后让我们的脚手架控制器MyModel -Repository（天啊，它正在工作）

包装不好装
