安装CORS后无法加载文件 [英] Cannot load file after installing CORS
问题描述
我已经使用所有默认设置在VS Express 2013中创建了一个基本的ASP.NET Web Api应用程序.我添加了一个控制器，它可以根据需要返回XML.
I have created a basic ASP.NET Web Api Application inside VS Express 2013 using all of the defaults. I added a controller and it returns XML just as I want.
一旦我安装了CORS软件包:
As soon as I install the CORS package:
Install-Package Microsoft.AspNet.WebApi.Cors -Pre
我什至无法运行该应用程序:
I can't even run the application anymore:
An exception of type 'System.IO.FileLoadException' occurred in mscorlib.dll and wasn't handled before a managed/native boundary
Additional information: Could not load file or assembly 'System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
我遵循了此博客文章中的所有说明: http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api 中对此问题一无所知.
I followed all of the instructions on this blog post: http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api which says nothing about this issue.
我尝试使用以下方法更新Web API:
I tried updating Web API with:
Install-Package Microsoft.AspNet.WebApi -Pre
但不幸的是，问题仍然存在
But still the problem persists unfortunately
在项目中，我使用的是WebApi.Hal，它依赖于Web.Api 5.0及更高版本.也许有重大变化吗?
In the project I am using WebApi.Hal which depends on Web.Api 5.0 and greater. Are there any breaking changes perhaps?
重现问题的绝对最小值
- 为Web 2013创建新的，完全为空的Web API项目VS Express
- 添加控制器并对其进行测试
- 安装CORS
- 文件加载错误-控制器不再起作用
-
升级Web Api-修复问题
- Create new, completely empty, Web API project n VS Express for Web 2013
- Add a controller and test it works
- Install CORS
- File load error - controller doesn't work anymore
Upgrade Web Api - fixes problem
安装软件包Microsoft.AspNet.WebApi -Pre
Install-Package Microsoft.AspNet.WebApi -Pre
我可以使用不能杀死其他所有功能的旧版CORS库吗?
Can I use an old version of the CORS library that doesn't kill everything else?

推荐答案
两步来解决问题
-
添加
dependentAssemblyassemblyIdentity name ="System.Web.Http" publicKeyToken ="31bf3856ad364e35"bindingRedirect oldVersion ="0.0.0.0-5.0.0.0" newVersion ="5.0.0.0"dependentAssembly
dependentAssembly assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" dependentAssembly
到web.config
to web.config
- 转到工具/库打包的管理器/管理Nuget包"以获取解决方案，然后单击"Microsoft ASP.Net MVC"，然后单击更新".
