Techtalk.Specflow error: Could not load assembly file or assembly

I have seen this question before but I believe it was not resolved. Basically my set up is this:
VS 2015
Specflow ver 1.9.0 (I downgraded to this from 2.1.0 based on other question which didn't help)

When I try to build my project, it comes with the follwoing error:

error Generation error: Could not load file or assembly 'TechTalk.SpecFlow, Version=, Culture=neutral, PublicKeyToken=0778194805d6db41' or one of its dependencies. The system cannot find the file specified.

I haven't asked a question in some time now so if I'm missing vital information regarding this, please let me know and I'll update.

Thanks in advance

Check your package.config and see if it has an entry for TechTalk.SpecFlow. If yes, then delete the entry from package config file ... as well delete all the assembly related to that dll. Re-install the specific version from NuGet and re-compile your project.

Per your comment it still targeting the new version newVersion="" and not the new version Version= Change your app.config like to be

<assemblyIdentity name="TechTalk.SpecFlow" publicKeyToken="0778194805d6db41" culture="neutral" /> 
<bindingRedirect oldVersion="" newVersion="" />
