Exception When Trying To Add SevenSpikes.Nop.Plugins

Hi,

I'm getting the following Exception when clicking 'Reload list of plugins' after copying all the Plugins provided with the Fashion theme to the Plugins folder on my server.

Exception information:
    Exception type: InvalidOperationException
    Exception message: The pre-application start initialization method Initialize on type Nop.Core.Plugins.PluginManager threw an exception with the following error message: Method 'get_Order' in type 'SevenSpikes.Nop.Plugins.Core.DependencyRegistrar' from assembly 'SevenSpikes.Nop.Plugins.Core, Version=2.5.375.4097, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Any thoughts?

Thanks, Kent.

Hi Kent,

Would it be able to tell us the assembly version of the SevenSpikes.Nop.Framework as well. Also you can try installing the SevenSpikes.Core plugin only.

We will investigate further what might be going wrong.

Thanks!

Hi,

I have tried installing just SevenSpikes.Core and I receive the same error.

The File version of SevenSpikeds.Nop.Framework.dll is 2.5.375.4097

Thanks,

Kent.

Hi Kent,

We just sent you an email as we need to further investigate this with your help.

I am getting the same exception but after I deployed the site the first time.

Hi,

We have already answered you in your ticket. Please do not duplicate forum posts and tickets!

I received the same error as "richhoude".  Could you post what the solution is.

I figured out this problem was caused by multiple issues.  

1) I did not have full trust configured on web server (GoDaddy, Arvixe, RackSpace)
2) I didn't have trust="full" in web.config in the root of the project.
3) Being that I didn't have at least medium trust I should have deleted the Plugins\Bin folder when upgrading from nopCommerce 3.60 to 3.70.  Now since I have full trust I do not need to delete these files manually.

Thanks yes i found that this line in the config made all the issues go away. <trust level="Full" />
