Error: could not find dependent assembly ‘System.Runtime, Version=4.1.1’

This error can occur when you have conflicting versions of a system (or any) assembly. The following is a .Net Framework feature that will redirect the assemblies to be the same, and thereby resolve the conflict:

      <dependentAssembly>
        <assemblyIdentity name="System.Reflection" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.1.1.0" newVersion="4.3.0" />
      </dependentAssembly>
