System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.SqlClient, Version=4.6.1.3

Hey
I have a some problem with this library when try to deploy to remote hosting.
On local it's working perfectly locally with Debug/Release modes.

My publish profile:

<?xml version="1.0" encoding="utf-8"?>
<!--
https://go.microsoft.com/fwlink/?LinkID=208121.
-->
<Project>
  <PropertyGroup>
    <DeleteExistingFiles>false</DeleteExistingFiles>
    <ExcludeApp_Data>false</ExcludeApp_Data>
    <LaunchSiteAfterPublish>true</LaunchSiteAfterPublish>
    <LastUsedBuildConfiguration>Release</LastUsedBuildConfiguration>
    <LastUsedPlatform>Any CPU</LastUsedPlatform>
    <PublishProvider>FileSystem</PublishProvider>
    <PublishUrl>bin\Release\net7.0\publish\</PublishUrl>
    <WebPublishMethod>FileSystem</WebPublishMethod>

    <SelfContained>false</SelfContained>
  </PropertyGroup>
</Project>

Then I'm copying all files by FTP to my server.
My application is starting without any issue, then in background process running some synchronization which using this library.
And I see in logs next:

System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.SqlClient, Version=4.6.1.3, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

I've analyzed NuGet references, but I didn't see that System.Data.SqlClient, Version=4.6.1.3 necessary somewhere.
And I couldn't install it, because VS is saying this:

NU1605: Warning As Error: Detected package downgrade: System.Data.SqlClient from 4.8.3 to 4.6.1. Reference the package directly from the project to select a different version. 
 AutoTools.Repository -> EFCore.BulkExtensions.SqlServer 7.0.0 -> EntityFrameworkCore.SqlServer.HierarchyId 4.0.0 -> EntityFrameworkCore.SqlServer.HierarchyId.Abstractions 4.0.0 -> dotMorten.Microsoft.SqlServer.Types 1.5.0 -> System.Data.SqlClient (>= 4.8.3)

Sorry, my bad
Don't sync runtimes and refs folders to my hosting.

Glad you solved it.
