wrong version of dependencies in "<plugin>.deps.json"

Hello @all,
I got an urgent problem that leads to an error "HTTP Error 500.30 - ASP.NET Core app failed to start " when visiting our webshop.
The stdout-log tells me

Unhandled exception. System.Exception: Unable to load one or more of the requested types.

and it's partly correct. the "Microsoft.Extensions.DependencyInjection.Abstractions.dll" DOES exists in the IIS websites root BUT in the version 7.2.0.0.

In my "<plugin>.deps.json" it has a reference to "Microsoft.Extensions.DependencyInjection.Abstractions 8.0.0"

I compared it with another plugins (misc.zettle) "deps.json" file and it contains a reference to
"Microsoft.Extensions.DependencyInjection.Abstractions 7.0.0".

so of coure the misc.zettle plugin works since it asks for version 7 which is in the websites root.
my plugin asks for version 8 but I don't know why.
The "deps.json" is autogenerated, so how do I change the reference to version 7?


my plugins "deps.json" contains references like this:

"Autofac.Extensions.DependencyInjection/8.0.0": {
        "dependencies": {
          "Autofac": "6.4.0",
          "Microsoft.Extensions.DependencyInjection.Abstractions": "8.0.0"}

whereas "misc.zettle.deps.json" contains

"Autofac.Extensions.DependencyInjection/8.0.0": {
        "dependencies": {
          "Autofac": "6.4.0",
          "Microsoft.Extensions.DependencyInjection.Abstractions": "7.0.0"}

So both depend on "Autofac 6.4.0" but on different versions of "dependencyinjection.abstractions"

Ideally, my plugin should NOT ask for a specific version of any reference orelse it can only be used in an environment with all the same dependency versions that my development environment uses.

Also, i compiled the "misc.zettle" plugin myself and... the generated "deps.json" now asks for the references in version 8.0.0

In my production system I installed "nopcommerce 4.60.5 nosource version".
in my dev environment I got the "source code version", of course.
So why does the "source code" generates "deps.json" files that differ from the ones the "nosource version" contains?

strange, i got an email saying there was a new post created to my topic, but I don't see it... so nobody has a solution for me?

Hi, are you sure, you have created a release build in the same nop commerce source version? i.e 4.60.5 ?

I mean this can happen if your production system is running on miner older version (i.e 4.60.3) & Your dev environment version is the newer one (i.e: 4.60.5) plz verify the same. or use this https://github.com/nopSolutions/nopCommerce/releases/download/release-4.60.5/nopCommerce_4.60.5_Source.zip  source to create a release build of your plugin.

I encountered a similar issue with stripe NugetPakcage but was able to fix it after I created a plugin release build from exact same version of nopcommerce which was running on my production.
