無法加載類型'System.IdentityModel.Tokens.JwtSecurityToken'

Question

我有兩個庫。一個消耗另一個，消費庫本身被Web應用使用。 Web應用程序返回下面的錯誤，而實例化類型的代碼（摻雜JWT簽名驗證）在兩個庫的單元測試中都成功執行。庫，應用程序是目標框架.NET 4.5.2我驗證了的Web應用程序的.csproj的文件中有一個有效的參考

<Reference Include="System.IdentityModel.Tokens.Jwt, Version=5.1.4.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">  <HintPath>..\packages\System.IdentityModel.Tokens.Jwt.5.1.4\lib\net451\System.IdentityModel.Tokens.Jwt.dll</HintPath> 
</Reference> 

我不覺得在GAC大會除去

C:\Program Files (x86)\Microsoft Visual Studio 11.0>gacutil /u System.IdentityMo 
del.Tokens.Jwt 
Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.17929 
Copyright (c) Microsoft Corporation. All rights reserved. 

No assemblies found matching: System.IdentityModel.Tokens.Jwt 
Number of assemblies uninstalled = 0 
Number of failures = 0 

我已經嘗試清理，重建，重新啓動，刪除/ bin和/ lib並重建，並且無所適從。就個人而言，這本身可能不是System.IdentityModel.Tokens.Jwt，但是我需要關於類型加載錯誤等疑難解答的指導。我已明確resintalled的.Tokens包以及所有套餐：

nuget install packages.config 

我仍然得到錯誤，而不是身材，而是隻執行：

Server Error in '/' Application.

我已經降級解決這個問題包System.IdentityModel.Tokens.Jwt 4.0

而且還有GitHub上的問題 https://github.com/aspnet/AspNetKatana/issues/76
