C# 无法加载文件或程序集System.Web.WebPages.Deployment

我正在开发系统网页，突然出现以下错误：

Could not load file or assembly 'System.Web.WebPages.Deployment, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

我已经验证了我的xml文件配置，一切看起来都很好。 这是堆栈跟踪：

我解决了这个问题，在项目的

web.config

中添加了下面的行…

在我在MANAGE NUGET中标记“Microsoft.AspNet.Mvc/5.1.2”、“Microsoft ASP.NET网页/3.1.2”之前，我尝试了任何方法，但没有任何效果（真的！！卸载VS并阅读了很多文章）

祝你好运

请尝试以下步骤

在参考资料中检查System.Web.Webpages的版本。假设您的版本为=X.X.X.X

2.在网络配置中

a、 首先添加程序集

<assemblies>        
    <add assembly="System.Web.WebPages, Version=X.X.X.X, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
  </assemblies>

b、 为运行时绑定程序集

<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
    <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31BF3856AD364E35" culture="neutral"/>
    <bindingRedirect oldVersion="0.0.0.0-X.X.X.X" newVersion="X.X.X.X"/>
  </dependentAssembly>        
</assemblyBinding>

3.确保添加了正确的密钥

<appSettings>
    <add key="webpages:Version" value="X.X.X.X"/>
</appSettings>

这对我有用。希望它也能对您有所帮助。

在我的情况下，这是由于我的笔记本电脑重新启动时崩溃，导致引用的程序集损坏

要解决此问题，请执行以下步骤

清理项目下列文件夹中的所有文件，或者只需单击“清理项目”和“清理解决方案”

• \垃圾箱
• \obj

清理Appdata临时文件夹 对于我的Win 7计算机，其位于windows 7中的C:\Users\your\u username\AppData\Local\Temp\Temp临时ASP.NET文件中

---

希望这有帮助

我通常会去编译代码的机器，在dos提示符下键入

C:> dir System.Web.WebPages.Depl* /s 

通常情况下，可能会有几个

c:/windows/Microsoft.Net/assembly/GAG_MSIL/System.web.WebPage/v....../

检查日期并确保与

System.Web.WebPages.dll相同
将其复制到目标机器所在的箱子中。这应该可以解决问题。
将此代码复制到Web.config的“配置”中，即可完成此操作。

  <runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
    <assemblyIdentity name="System.Web.WebPages.Deployment" publicKeyToken="31BF3856AD364E35" culture="neutral"/>
    <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/>
  </dependentAssembly>
</assemblyBinding></runtime>


我写了一篇长篇文章来记录这个问题，以备将来使用，但我将把解决方案放在这里供其他人使用：

您需要安装WebMatrix
长话短说GAC MSIL缺少所需的DLL，需要安装它们。您可以安装WebMatrix 1.0.0.0和2.0.0.0两个版本，因为它们可以很好地共存；或者只安装您需要的一个：

尝试在Web bin目录中复制粘贴或包安装System.Web.WebPages.dll

你可以从NuGet画廊拿到它


确保版本匹配。
您是从项目中引用的吗？我有这个条目，但仍然存在问题。就像User37…写的一样，还需要System.Web.WebPages.Deployment的条目，这很奇怪-publicKeyToken也是一样的。对我来说，这个问题是在清除了全局程序集缓存后出现的，它严重破坏了我的.net framework安装。“旧版本”是一个很大的范围，“新版本”是你的[System.Web.WebPages.Deployment.dll]版本；您可以在“C:\Program Files（x86）\Microsoft ASP.NET\ASP.NET Web Pages\v2.0\Assemblys”中获得[dll]版本。这对我来说很有效，但这确实让我很生气，因为这个问题不知从哪里冒出来。我在工作时从一台旧的笔记本电脑迁移到一台新的笔记本电脑，我的网站拒绝加载。我尝试过做各种各样的事情，这就是成功的原因。谢谢你弄明白了。
