My hoster upgraded from .NET 4.0 to 4.5 which has caused issues with NopCommerce 2.6.
I could not edit pages under the Admin panel and going into settings in your plugins would cause page errors.
After searching at NopCommerce I found out that the dll files "FluentValidation.dll" and "FluentValidation.Mvc.dll" that NopCommerce uses, need to be updated to 3.4.0 in order for NopCommerce to work on .NET 4.5.
I followed Andrei's suggestion here on how to do it:
After I've replaced the dll files, build the solution and ran the project again, it came up with this error (some of it is in Danish but I hope you can understand the error anyway)
This is caused by the plugins I have in my folder and I found out this error only occurs when the nop-templates plugins are in the plugin directory.
If I remove them, the webshop loads succesfully.
As you can see from the error message above, it seems the nop-templates plugins are referencing to an old version of "FluentValidation, Version=18.104.22.168".
I suspect that is the reason why the plugins fail to load is because my webshop now is using FluentValidation, Version=22.214.171.124
So can you make a new version of the nop-templates that uses FluentValidation, Version=126.96.36.199 or how can I solve the problem so your plugins will work with .NET 4.5?
Thanks in advance
