Erro on Ninject: Sequence contains no elements

This error appear just when I publish on Azure server:
Sequence contains no elements

I'm not sure this error is because of Ninject. I've tried all the tips with similar errors, but it seems that is a generic error.
I tried to run the same code on several machines and this error does not happen only when the public Azure.
If you have gone through something and can help, thank you very much.

I found the problem, on Azure when I published I didn't select the option "Remove additional files at destination" on publish screen's Settings tab.

Consequently the publish didn't remove old DLLs that I didn't use anymore. I cleared all files on Azure and published again and it worked.

After that, I selected the option "Remove additional files at destination" when publishing and it didn't happen again.
