Question

在vs2012中，我曾经使用过史蒂夫·桑德森的mvcScaffolding Package这个包，我可以使用单元测试和带有存储库和依赖注入的控制器来构建Action Methods。我的问题很简单。在vs2013中有没有办法这样做？当我在vs2013中安装软件包时，出现以下错误：

Answer 1

我们正在转向新的Scaffolding系统，但是现在，以管理员身份运行VS并使用我们已更新的-pre版本：

Install-Package MvcScaffolding -Version 1.0.8-vs2013 -Pre

我会写博客。

Answer 2

您得到的错误是它无法创建VS IDE（EnvDTE.DTE）的实例。该脚手架包引用了旧版本的VS IDE，因此在VS2013中无法使用。该项目必须更新才能正确支持VS2013。

Codeplex项目看起来好像很久没有更新了，所以我的猜测是，除非项目移动到不同的开源存储库，否则它已经死了。

由于ASP.NET现在内置了自己的脚手架，我建议现在是时候转换了。

Answer 3

在命令行中尝试： cd C：\ Program Files（x86）\ Microsoft Visual Studio 12.0 \ Common7 \ IDE \ devenv.exe / setup＆＃34; Extensions \ Microsoft \ Web \ Mvc \ Scaffolding \ Microsoft.AspNet.Scaffolding.Mvc.5.0.dll＆＃34;

Answer 4

为了解决VS2013 Update 4上的这个问题，我将不得不从所有模块上卸载。\ packages directorie删除所有T4 *，从VS退出。

再次输入，并使用来自witttness的解决方案，在包管理器控制台上执行：安装包MvcMailer-vs2013 -pre和voilá，从那时起它的工作......

感谢您的一切

Answer 5

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。

干杯。
