我在我的应用程序中使用MVC 5，WCF和Unity框架。

当我运行WCF服务时，我得到以下错误：

Server Error in '/' Application.

我在WCF项目中添加了System.Web.WebPages.Razor，Version = 3.0.0.0，仍然存在相同的错误。

有人知道如何解决这个错误？

确保您的项目定位为.net 4.5，所有引用都是有效的，并且Web AspNet.WebPages。*位于bin(Release / Debug)文件夹中。

您还可以尝试在包管理器控制台中使用此命令重新安装Microsoft.AspNet.WebPages nuget软件包

> Update-Package –reinstall Microsoft.AspNet.WebPages

我找到了一个类似的问题,但没有解决我的问题.

Could not load file or assembly ‘Antlr3.Runtime’ or one of its
dependencies. This assembly is built by a runtime newer than the
currently loaded runtime and cannot be loaded

我只在IIS中收到此错误.我正在尝试部署到IIS 7.5.我将应用程序池设置为4.0,Integrated.

早些时候一切都很好.安装框架4.5 VS 2012 Express后,我使用MachineKeyCryptography获得了异常.所以我卸载了4.5框架和VS 2012,因为这个混乱正在发生.

我得到的例外情况如下.

你需要在IIS中更改它的运行时版本.
右键单击虚拟目录
并单击高级设置
将其更改为正确的池设置.我可以说重新安装后你的游泳池设置不正确.

您可以找到该过程

In Application Pools-> Select your site ->Set Application Pool
Defaults -> Select your correct version

如果这不起作用,此时您可以做的首选是从系统中引用框架4卸载所有.Net安装.清理系统,然后重新安装所有内容.

但我发现你使用的是IIS 7.5.因此,您可以发现许多功能变化,需要谨慎处理.您可以尝试在尝试重新安装之前设置应用程序池和其他设置.

我刚刚将一个Asp.Net Web Api 2.2项目上传到生产服务器,并得到标题中的错误.在我的Web.config我已经有：

<dependentAssembly>
    <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.2.0" newVersion="5.2.2.0" />
  </dependentAssembly>

文件确实存在于bin中.会造成什么？所有我的Asp.Net Web API文件都是最新的,并显示5.2.2的版本.它在我的开发机器上工作正常.

在System.Web.Http和System.Web.Http.WebHost程序集的属性中将copy Local设置为true,并重新部署程序包.

如果这不能解决您的问题,请尝试重新安装NuGet软件包.这将有助于纠正破坏的依赖关系.从包管理控制台,运行以下命令：

Update-Package Microsoft.AspNet.WebApi -reinstall

确保安装System.Web.Http.WebHost以及.

我正在尝试创建一个水晶报告,我是该领域的新手.我从 this tutorial post创建了一个水晶报告,但它似乎不起作用.

BadFormatimageException是您为32位体系结构编译程序时收到的错误,并将尝试加载64位库或反之亦然.从错误中,您可以参考log4net(一个众所周知的日志库). 首先,检查您正在创建应用程序的cpu类型(x86,x64,Anycpu) 其次,检查log4net的位数(你应该引用你的应用程序的相同位数) 第三,检查运行的操作系统IIS. (如果是x64和您的应用程序32,请在应用程序池的高级设置部分中将“启用32位应用程序”设置为true)
