PCL project not compiling after updating all the installed NuGet portable libraries

Question

Everything was working fine in my Portable-Class-Library project until I updated all the installed portable libraries. It has stopped compiling. Throws the following errors for the nuget libraries installed.

How to point it to System.Runtime version 2.6.3.0?

Answer 1

Fixed the problem.

The PCL project's app.config was pointing to 2.6.3.0 version of System.Runtime. I changed it to point to 1.5.11.0, the previous one, and it compiled fine.

<?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>

Make sure your PCL version supports the dependencies you need. Here is a spreadsheet regarding the current support courtesy of CheeseBaron.

Note - Because this is still in it's infancy of supporting certain libraries, you'll have to find the right one that works for your project.
