Error with specflow in visual studio 2012 with <unitTestProvider>

unit-testing selenium visual-studio-2012 specflow build-error

I am using selenium, Specflow and nUnit to run automated tests with visual studio. The code was working with visual studio 2010. After I installed visual studio 2012, selenium and Specflow again (I think I did it right), it stopped working. First, the steps didn't recognize their definitions and I think I fix it writing [Binding] in all the c# files that contains their definitions. Now when I try to build the project it shows an error that I can't solve to all feature files.

It shows 50 errors (the same number of Specflow feature files I have), they are all the same, and it says this:

Error: Generation error: SpecFlow configuration error -> The element <unitTestProvider> may only appear once in this section.

I don't know how to fix this. I hope somebody can help me, I am really worry because of this.

Keep only one attribute as unitTestProvider name="SpecRun" or unitTestProvider name="NUnit" in app.config

This error is caused by two 'unitTestProviders' in app.config.
