SpecFlow build error "Could not load file or assembly 'TechTalk.SpecFlow'" in VS 2015

Question

I am getting below error when try to compile SpecFlow project in VS 2015.

error Generation error: Could not load file or assembly 'TechTalk.SpecFlow, Version=1.9.0.77, Culture=neutral, PublicKeyToken=0778194805d6db41' or one of its dependencies. The system cannot find the file specified.

Following are the references I added.

Answer 1

Could be your temp extensions cache path files are corrupted or missing C:\Users\<user>\AppData\Local\Temp\VisualStudioTestExplorerExtensions\

Close visual studio and delete all content from C:\Users\<user>\AppData\Local\Temp\VisualStudioTestExplorerExtensions Open visual studio and try running the test.

Answer 2

This is most likely caused by one of the extensions still depending on specflow 1.9. You should be able to install that specific version to resolve your issues.
