Note:published project on IIS works well in win7 and win8. My project isn't based on ASP.NET MVC. Please help me.

注意：在 IIS 上发布的项目在 win7 和 win8 下运行良好。我的项目不是基于 ASP.NET MVC。请帮我。

We're using Azure cloud to run a deployment and I got the same error. Since you can't really install packages onto the server instances, the way to solve this is to go into References for your project, find the reference to the library that it's complaining is missing, go into properties, then set Copy Local to True. Redeploy and you're all set.

我们正在使用 Azure 云来运行部署，但我遇到了同样的错误。由于您无法真正将软件包安装到服务器实例上，因此解决此问题的方法是进入您的项目的 References，找到它抱怨缺少的库的引用，进入属性，然后将 Copy Local 设置为 True。重新部署，一切就绪。

I'm assuming this is a new machine, seeing as you have the new OS and different version of Visual Studio. I think you need to install MVC Framework version 2, as that's what your Umbraco install is expecting. You can either install the Framework, and get the DLLs into your GAC, or copy the DLLs from your good system to the bin folder of your web application.

我假设这是一台新机器，因为您拥有新的操作系统和不同版本的 Visual Studio。我认为您需要安装 MVC 框架版本 2，因为这是您的 Umbraco 安装所期望的。您可以安装框架，然后将 DLL 放入您的 GAC，或者将 DLL 从您的良好系统复制到您的 Web 应用程序的 bin 文件夹中。

Note, you're saying your project "doesn't use" MVC, but I think you'll find Umbraco does. The error, at any rate, is telling you that the system expects to find it.

请注意，您是说您的项目“不使用”MVC，但我认为您会发现 Umbraco 使用了。无论如何，该错误告诉您系统希望找到它。

Umbraco 4.11.3 doesn't use MVC2, it uses MVC3 so I would guess that you have a reference in your web.config to the MVC2 library, possibly in the compilation > assembliessection. It should look something like this:

Umbraco 4.11.3 不使用 MVC2，它使用 MVC3，所以我猜你在 web.config 中有一个对 MVC2 库的引用，可能在compilation > assemblies部分。它应该是这样的：

<compilation defaultLanguage="c#" batch="false" targetFramework="4.0" debug="true">
  <assemblies>
    <!-- ASP.NET 4.0 Assemblies -->

The correct fix for this issue is to:

此问题的正确解决方法是：

1. Right-click on Referencesin your Solution Explorerand choose Manage NuGet Packages
2. On the left side select Updates
3. In the middle section select Microsoft ASP.NET MVC
4. You should see an Updatebutton appear in your selection, click on it

1. 右键单击References您的Solution Explorer并选择Manage NuGet Packages
2. 在左侧选择 Updates
3. 在中间部分选择 Microsoft ASP.NET MVC
4. 您应该会看到一个Update按钮出现在您的选择中，点击它

That's it...accept any T&Cs that might pop-up and either publish or run your project locally. If you're still having problems running your project locally, try closing Visual Studio deleting the .SUO file for the project and try opening the solution again...try running again.

就是这样......接受任何可能弹出的条款和条件，并在本地发布或运行您的项目。如果在本地运行项目时仍有问题，请尝试关闭 Visual Studio，删除项目的 .SUO 文件，然后再次尝试打开解决方案...尝试再次运行。
