我的 Portable-Class-Library 项目一切正常，直到 我更新了所有已安装的可移植库。 它已停止编译。为安装的 nuget 库抛出以下错误。

如何指向 System.Runtime 版本 2.6.3.0？
最佳答案
解决了问题。
PCL 项目的 app.config 指向 2.6.3.0 版本的 System.Runtime。我将其更改为指向 1.5.11.0，即之前的版本，并且编译正常。
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
// <!-- <bindingRedirect oldVersion="0.0.0.0-2.6.3.0" newVersion="2.6.3.0" /> -->
<bindingRedirect oldVersion="0.0.0.0-1.5.11.0" newVersion="1.5.11.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
关于c# - 更新所有已安装的 NuGet 可移植库后，PCL 项目未编译，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20196552/
