问题描述
我正在使用PostSharp，并且刚刚将我的解决方案升级到.NET 4.6.2
I am using PostSharp and have just upgraded my solution to .NET 4.6.2
在安装软件包 System.ValueTuple 后，尝试构建启用了PostSharp的主项目时，输出中出现 BindingException:程序集绑定策略不明确异常.
After installing the package System.ValueTuple I get a BindingException: Ambiguous assembly binding policies exception in the output when trying to build the main project with PostSharp enabled.
Unhandled exception (4.3.30.0, postsharp-net40-x86-srv.exe, CLR 4.0.30319.394802, Release): PostSharp.Sdk.CodeModel.BindingException: Ambiguous assembly binding policies: Assembly 'system.runtime, version=4.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a' redirects both to 'system.runtime, version=4.1.1.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a' and 'system.runtime, version=4.0.20.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a'.

这是我的 Web.config
<dependentAssembly>
<assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.1.1.0" newVersion="4.1.1.0" />
</dependentAssembly>
