Add custom action in Wix with multiple dependencies

I have a problem when trying to add a custom action in Wix with C# DLL. I have a custom action for checking the Postgresql server connection and in the C# project, I use Npgsql for checking it. Everything is ok with Npgsql ver 3.1.0. But when I upgrade Npgsql to ver 5.0.3 (the lastest ver), build the MSI installer again, hit the button to run the custom-action, an error occurred

Could not load file or assembly 'System.Threading.Tasks.Extensions'

I know that with the new version it required System.Threading.Tasks.Extensions. But I don't know how to embedded into my custom-action DLL.

These are the dependencies of ver 5.0.3: enter image description here

Updated, this is the full logs when error happened

Apparently, it's maybe a bug of Npgsql: https://github.com/npgsql/npgsql/issues/2677

But I finally found a solution to this. Just create a config file app.config or modify your existing .config file like this

For the version of the packages, check it in your project's reference enter image description here

Had a similar problem. And details appeared to be important. In addition to the answer above:

Somehow Nuget created App.config file and added binding redirects to App.config with Build Action set to None, but there is a CustomAction.config which contains different binding redirects. After deleting App.Config and moving binding redirects from it to CustomAction.config it worked. It's also important to mention that Build action for the *.config file should be set to Content. Copy to output Directory - Do not Copy.
