未能加载文件或程序集“System.Threading.Tasks.Extensions, Version=4.2.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51”或它的某一个依赖项
Web.config 有问题:
</configuration> 下 </runtime> 下<assemblyBinding>里添加: 来指定你当前使用的版本,记得把对应的dll拷贝到bin下
<dependentAssembly>
<assemblyIdentity name="System.Threading.Tasks.Extensions" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.2.0.1" newVersion="4.2.0.1" />
</dependentAssembly>
