這發生在TDMS.WebServices項目中，該項目是.net 4.5 Web API 2.0。我們也有一個MVC5項目。無法加載文件或程序集'System.Web.Helpers'

從bin文件夾中刪除.dll並再次編譯修復它。重建會將DLL帶回並刪除它。

有些東西是注入system.web.helpers.dll到bin文件夾，我不知道是什麼造成它，但我懷疑它可能與MVC項目有關的System.Web.Helpers

更新：

這是新的錯誤我重做引用後得到：

如果它，如果你從文件夾中刪除該DLL再次工作，這很可能是因爲它是從GAC加載的。你的一個項目是引用這個DLL，並且它在編譯時會將一個本地副本放入bin文件夾中，這會導致它中斷（bin文件夾具有更高的優先級）。檢查GAC以查看存儲的版本，然後再次編譯並檢查放入文件夾的版本。他們不一樣。 – JuanR

這似乎是問題的發生，我該如何解決它？我不相信我可以將該副本更改爲本地MVC項目 – CuriousDeveloper

您需要做的是參考正確的版本。哪一個更高？ GAC還是本地參考？ – JuanR

你說得對，它正在從MVC簡稱。 System.Web.Helpers通常是您在NuGet上可以找到的包Microsoft.AspNet.WebPages的一部分。在某些運行時環境中，它安裝在GAC中並因此公開可用。

從控制檯的NuGet，運行

Update-Package Microsoft.AspNet.WebPages

請確保您有在web.config中重定向：

<dependentAssembly> 
    <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" /> 
    <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" /> 
</dependentAssembly>

它沒有發現任何Microsoft.AspNet.WebPages的更新，我確認web.config條目是確切的 – CuriousDeveloper

Add the reference of System.Web.Helpers.dll file to your project, 

and add below setting in web.config file 

<dependentAssembly> 
    <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" /> 
    <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" /> 
</dependentAssembly>
