compilation error

My website has this error:
Compiler Error Message: CS0234: The type or namespace name 'BusinessLogic' does not exist in the namespace 'NopSolutions.NopCommerce' (are you missing an assembly reference?)

Source Error:



Line 138:        <add namespace="NopSolutions.NopCommerce.BusinessLogic.Products.Specs"/>
Line 139:        <add namespace="NopSolutions.NopCommerce.BusinessLogic.Products"/>
Line 140:        <add namespace="NopSolutions.NopCommerce.BusinessLogic.Profile"/>
Line 141:        <add namespace="NopSolutions.NopCommerce.BusinessLogic.Promo.Affiliates"/>
Line 142:        <add namespace="NopSolutions.NopCommerce.BusinessLogic.Promo.Campaigns"/>

When I try to add an assembly reference to Nop.BusinessLogic it says that it's missing an assembly manifest.  NopCommerce works fine on my computer but everytime I try to upload it to my web server it won't run.  I watched the installation video and all they did was upload it and didn't have any of the problems that I'm experiencing.  Is there some incompatibilities with my web server and nopCommerce?

Thank you.

Hi Deccks

I would be interested to know what happened for you.. got the same problem

My problem was that I had a .dll file in the Bin directory that did not get uploaded completely.  I had to go examine each file by its file size side-by-side in my FTP client to see which one did not get uploaded completely.  I found the file and re-uploaded it.  After that, everything worked fine.
