Upgrade my plugins from 3.50 to 3.60 Version

I tried to integrate my plugins that i developped under 3.5 nopcommerce version, i modify the file Description.txt by modifying the line of version.

But this error happens when i reload the list of plugins under /Admin/Plugin/List.

This is the message of error :

Erreur source:

Ligne 149 :                            foreach (var t in pluginDescriptor.ReferencedAssembly.GetTypes())

There's a little more to it than simply changing the version number in the description.txt.  You'll usually, at a minimum, need to recompile against the new binaries, you'll often find new methods on interfaces and classes the plugin is using or inheriting from.

If you don't have the plugin source, you'll need to wait or ask for the plugin developer to upgrade the plugin to 3.6.

To add on to what was already said you might also need to update your nuget packages.  Usually from one nopCommerce version to the next the packages get updated and if your plugin is still referencing a different version that can cause issues.

Great point about the nuget packages

part for the nuget
check the following changesets when upgrading plugins to 3.6
