Erro on Ninject: Sequence contains no elements

Question

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.

What's the code performing the `Enumerable.Single` call? What's it performing `Single` on? — BatteryBackupUnit, Sep 09 '15 at 13:43
I do not know where he's going to throw the error. I can not debug because this cloud. — Marcus Braga, Sep 09 '15 at 13:49
Yes but at least you can have a look into the source code of `Ninject.Web.Mvc.NinjectMvcHttpApplicationPlugin.Start()` and see where it's calling `Single`! — BatteryBackupUnit, Sep 09 '15 at 13:59

What *exactly* have you already tried in order to fix the issue? Have you had a look at [these](http://stackoverflow.com/questions/24776799/sequence-contains-no-elements-exception-when-initializing-ninject?rq=1)? — BatteryBackupUnit, Sep 09 '15 at 14:02
Yes I try it, but it's not the case! I don't know how reproduce the erro becouse I don't know where is the problem. Sorry I'm new here and I don't know well how to ask for help. — Marcus Braga, Sep 09 '15 at 14:09
did you have a look at [this](https://github.com/ninject/ninject.web.mvc/issues/24)? — BatteryBackupUnit, Sep 09 '15 at 15:16
Yes man! But I don't have duplicate ninject in my projects. In local machine work fine the problem is when I publish the project on Azure. If whas the problem it's not work on in local machine. — Marcus Braga, Sep 09 '15 at 16:55

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.

Thanks Marcus. That helped me. I (foolishly) tried the continuous integration option from Bitbucket to Azure, and that royally messed things up for me. I got the same error as you when I went back to publishing manually. – oflahero Sep 21 '15 at 14:04

In my case this issue was happening in UAT but not on my machine.

The reason for that is I changed namespace and as result in release folder there were two libraries with the same class.

I had to clean up release folder and publish it again. All good now
