Strongly named assembly required on our Trados Studio plugin.

Hi guys we have this issue on a Verication plugin that we are developing. The thing is that from our Verifier Plugin code we are referencing to an assembly for another project by NuGet (It is a custom library developed by us too) 
We could compile and implemented it but when we try to run it from Trados Studio it is throwing an exception with the following message:
Could not load file or assembly 'Our.Referenced.Assembly, Version=1.0.1.11, Culture=neutral, PublicKeyToken=null' or one of its dependencies. A strongly-named assembly is required. (Exception from HRESULT: 0x80131044)

We was trying to sign our refereced assembly with this guide: http://www.geekzilla.co.uk/ViewCE64BEF3-51A6-4F1C-90C9-6A76B015C9FB.htm
But it is still failing..

Can you please let us know how to sign our assembly to be referenced from our Verification Plugin. 

Thanks in advance!
