【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

安装包System.ValueTuple 后，当我尝试在启用 PostSharp 的情况下构建主项目时，输出中出现 BindingException: Ambiguous assembly binding policies 异常。

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Web.config中的相关绑定重定向

  <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>

【解决方案1】：

这可以通过升级到 PostSharp 5.0 预览版来解决

https://www.nuget.org/packages/PostSharp/5.0.21-preview https://www.postsharp.net/downloads/postsharp-5.0

【讨论】：

这不是解决方案。 PostSharp 5+ 许可与 PostSharp 4 不兼容。
