无法加载文件或程序集'WebMatrix.Data`

Question

我将MVC4更新为MVC5。 当您运行应用程序时，我收到一个错误，我没有WebMatrix.Data 。 我安装了PM> Install-Package WebMatrix.Data 。 现在，当您开始进入浏览器时：

无法加载文件或程序集'WebMatrix.Data，Version = 3.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35'或其依赖项之一。 位于程序集的清单定义与程序集引用不匹配。 （HRESULT异常：0x80131040）

有人知道怎么修这个东西吗？

Answer 1

进入： Tools > NuGet Package Manager > Package Manager Console

并运行以下命令：

PM> Install-Package Microsoft.AspNet.WebPages.Data

Answer 2

这对我有用。 花了好几个星期才搞清楚。

确保您的目标框架符合您的要求（我有4.6.1 ）。

进入： Tools > NuGet Package Manager > Package Manager Console并执行以下命令。

Uninstall-Package Microsoft.AspNet.WebHelpers
Uninstall-Package Microsoft.AspNet.WebPages.OAuth
Uninstall-Package Microsoft.AspNet.WebPages.WebData
Uninstall-Package Microsoft.AspNet.WebPages.Data

Install-Package Microsoft.AspNet.WebPages.Data
Install-Package Microsoft.AspNet.WebPages.WebData
Install-Package Microsoft.AspNet.WebPages.OAuth
Install-Package Microsoft.AspNet.WebHelpers

希望这有助于任何尝试其他解决方案而没有运气的人。

Answer 3

这实际上是一个遗留库。 如果要从MVC 4升级到5，则应该安装Microsoft.AspNet.WebPages.Data。

PM> Install-Package Microsoft.AspNet.WebPages.Data

Answer 4

这也有效

Update-Package Microsoft.AspNet.WebPages.Data

Answer 5

从您的包管理器控制台我可以看到您的项目已成功将“WebMatrix.Data 2.0.30506.0”添加到xxx。

因此，请将您的web.config与WebMatrix.Data 2.0.30506.0同步

Answer 6

安装MVC 4（不是运行时但是完整版）为我修复了它。
