解决方案的
DLL在公布（部署环境）缺失。这就是为什么它是工作在当地即Visual Studio中而不是在Azure的网站环境的原因。只是做
复制本地=真正在装配的属性（ System.Web.Http.WebHost ），然后做了重新部署，它应该工作的罚款。如果您收到类似的错误，即一些其他装配丢失，然后进行组装copylocal = TRUE并重新部署，反复重复这一点 - 如果你不能确定它的依赖
I created a web project and it runs well in Visual studio. However, I got the following error after published it to azurewebsites. What can cause the issue?

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

解决方案The
dllis missing in the published (deployed environment). That is the reason why it is working in the local i.e. Visual Studio but not in the Azure Website Environment.Just do
Copy Local = truein the properties for the assembly(System.Web.Http.WebHost) and then do a redeploy, it should work fine.If you get the similar error i.e. some other assembly missing, then make that assembly to copylocal=true and redeploy, repeat this iteratively - if you are unsure of its dependencies.
