【问题描述】:
我正在开发一个 ASP.NET Web 窗体网站,并且经常遇到如下运行时异常:
Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
=== Pre-bind state information ===

它们总是因为“错误”版本的程序集(它似乎总是 Newtonsoft.Json)被复制到 Bin 目录,尽管站点根目录中的 packages.config 具有:
<package id="Newtonsoft.Json" version="11.0.2" targetFramework="net45" />
并且 web.config 包含:
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-11.0.0.0" newVersion="11.0.0.0" />
</dependentAssembly>
谁能解释一下是什么决定了哪个程序集被复制到Bin 目录,为什么这种情况不断发生以及如何防止它在未来发生?
