Error while adding class reference HtmlAgilityPack to class

I am getting an error adding this to my class, does anyone know a solution for this? Using the framework 4.5.

Could not load file or assembly 'HtmlAgilityPack, Version=1.4.9.0, Culture=neutral,   PublicKeyToken=bd319b19eaf3b43a' or one of its dependencies. The located assembly manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

      

        
        
        
      

    

I have this in my .config package

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="HtmlAgilityPack" version="1.4.9.0" targetFramework="net45" />
</packages>

      

        
        
        
      

    

packages give an error that it is not declared

I tried to add it for debugging, enable it locally, but nothing seems to work to make it work.

Update:

still the same error corrected it like this, but not sure if it is correct:

<configuration>
<packages>
    <package id="HtmlAgilityPack" version="1.4.9.0" targetFramework="net45" />
</packages>
<dependentAssembly>
    <assemblyIdentity name="HtmlAgilityPack" publicKeyToken="bd319b19eaf3b43a" culture="neutral" />
    <bindingRedirect oldVersion="1.4.5.0-1.4.7.0" newVersion="1.4.9.0" />
</dependentAssembly>
</configuration>
